SATA hard drive application Raiders
(I published on the network equipment sector before, but it seems that there are very few people there, it is not popular, huh, huh, put it here)
Look at the content of the extracted post, I feel that the knowledge about SATA is still relatively small. More and more people with SATA hard drives. Just this two days, I will find a detailed article, I hope to help my friends. . . The entire article is divided into five parts: Graphic Tutorial: SATA hardware hardware installation is clear, white, use SATA hard drive

Photo tutorial: SATA hardware hardware installation knows SATA hard drive
Compared with traditional parallel ATA hard drives: first is the speed of SATA, in addition to this, SATA hard drive also has easy installation, easy heat, support hot plug, etc., these are Parallel ATA hard drives cannot be compared to it. Because of this, the SATA hard drive has been sought after by the hardware players through the market, and has become the focus of market attention. But not all the motherboards support SATA hard drives, some old boards do not directly support SATA hard drives, if you just bought a SATA hard drive, you must also purchase a SATA interface card. After installing the above conditions, you will teach you to install the SATA hard drive. However, we must prepare some tools before installation: first is a screwdriver; secondly, the data power cord used to secure the hard disk and the hard disk is ready. Since the current hard drive is very hot in the work, a harsh heat dissipation environment will seriously affect the service life of the hard disk. So now we choose an easy-to-heat-dissipating position in the chassis. 1. Fixed the SATA hard drive, which is different from the traditional parallel hard drive. 2. Connect the data cable and power cord for your hard drive. The SATA hard drive is very different from the traditional hard drive, and the SATA hard drive uses a 7-pin thin cable rather than a common 40/80 pin flat hard drive line as a channel of transmission data (Figure 1). The advantage of thin cable is that it is very thin, so it is very easy to bend. The traditional hard drive wire is very difficult, due to wide, often cause a partial heat dissipation. There is no shortcomings in thin cables, which do not hinder the flow of air inside the chassis, which avoids the production of the heat zone, thereby improving the stability of the entire system. Next, connect the SATA hard drive to the SATA interface on the interface card or motherboard with a thin cable. Since SATA uses a point-to-point connection, each SATA interface can only connect to a hard disk, so it is not necessary to set jumpers as parallel hard drives, and the system automatically sets the SATA hard drive as a primary disk.

3. Connect the power cord for the hard disk. Like the data line, the SATA hard disk also does not use the traditional 4-pin "D-type" power interface, and the 15-pin flat interface (Fig. 2) is used, and the voltage used is 12V, 5V and 3.3V, if your power does not provide this interface, you need to purchase a power supply or converter connector that supports SATA hard drive (Figure 3). Some SATA hard drives provide 4-pin "D-type" and 15-pin flat interface (Figure 4), which can directly use the original power supply. After all of these are complete, you need to check again. Confidence, you can cover the chassis after accurate.

4. Install the driver. The SATA hard drive is fully compatible with traditional parallel hard drives, so there is generally no problem in the installation of the driver. If the operating system you use is Windows 9x / ME, just enter the BIOS, you can set it simply under the SATA option inside. However, SATA hard drives may have some problems when installing Windows XP. Since Windows XP cannot identify the SATA hard drive connected to the interface card, the user must manually install the SATA hard drive driver. During the installation process, press the F6 key when Windows XP is looking for SCSI devices, then insert the drive floppy disk attached to the SATA interface card, so you can install Windows XP normally (detailed operation See when the Serial ATA hard drive encounters Windowsxp clear white Use the SATA hard drive from the setting partition to the installation
As I865, I875, KT600, etc., the motherboard, which supports SATA serial port hard drive, has chosen the SATA hard drive when more and more manual machines. However, since the SATA hard drive is different from the parallel PATA hard drive, its installation setting portion will be different. If the settings are not clear, there is a problem in the future use, so this article will explain the use of the SATA hard drive from the BIOS settings (key part, the basis of the following items), partition, installation system, and the system, which is also Will explain the considerations of the SATA hard drive coexist with the old parallel hard drive. First, the BIOS setting part is substantially consistent due to the BIOS of each motherboard, but the principle of setting is basically consistent. Here is a few typical BIOS settings. I believe that readers can resolve this article according to the actual situation of their motherboard BIOS. problem. 1. South Bridge is the motherboard of ICH5 / ICH5R, with ASUS P4C800 as an example, this motherboard chipset is I865PE, the South Bridge is ICH5 / ICH5R. After entering the BIOS, select the IDE Configuration Menu under Main, you can select two IDE operation modes: Compatible mode and Enhanced Mode below onboard IDE Operate Mode: compatible mode and enhanced mode. Among them, compatible mode Compatible Mode, you can understand the corresponding port of the SATA hard drive to the parallel ID channel, there will be three options in the IDE port settings below when you choose this mode: Primary P-ATA S-ATA: Parallel IDE hard drive occupy the primary IDE channel of IDE0 1, serial SATA hard drive occupies the slang channel (Secondary IDE CHANNEL). That is to say, the port corresponding to the second parallel IDE interface on the motherboard is not available. Secondary P-ATA S-ATA: In contrast to the above, the corresponding port corresponding to the first parallel IDE interface (PRIMARY P-ATA) is not available because the SATA hard drive is occupied. P-ATA Ports Only: Blocks the serial SATA hard disk interface, only parallel interface devices can be used. Note: In the first two modes, the SATA1 interface on the motherboard automatically corresponds to the primary disk location in the IDE channel, and the SATA2 interface automatically corresponds to the slave position in the IDE channel. When the selection mode is enhanced, the word setting under the port set is encen, and there are three options: P-ATA S-ATA: parallel and serial hard disk coexistence mode, at this time SATA and PATA channels are uninterrupted independently, theoretically, 4 P-ATAs and 2 S-ATAs can pick up 6 devices at the same time, in fact, according to different motherboards, some South Bridge chips only support 4 ATA devices . At this time, the SATA1 hard disk corresponds to the Third IDE MASTER (the third IDE channel primary disk), and the SATA2 hard disk corresponds to the FOURTH IDE MASTER (the fourth IDE channel primary disk). S-ATA: Serial hard disk enhancement mode, at this time, four serial hard drives are supported, but also to look at the motherboard (if it is the ICH5R chipset such as P4P800, if you want to group RAID mode, you must choose this. And set the Configure S-ATA As RAID item to Yes, the S-ATA BootROM item is set to Enable, and the "Ctrl I" is pressed when the BIOS automatically detects.
P-ATA: It is still a mapping mode. The SATA hard disk occupies the first IDE channel. SATA1 corresponds to the first channel of the primary disc, and SATA2 corresponds to the slave plate of the first channel. When you use traditional operating systems such as WIN98 / WIN NT / WIN2000 / MS-DOS, since they only support 4 IDE devices, choose Compatible Mode, and select IDE according to your actual hard drive The corresponding option in Port Settings; When you use a new operating system such as WinXP / Win2003, you can select Enhanced Mode Enhanced Mode to support more devices. Of course, if you install the Win98 Win XP dual system, you have to choose CompAtible Mode. In addition, some motherboard BIOS has bugs, causing the SATA hard drive correctly when installing a Windows 98SE system on a single SATA hard drive (such as ASRock P4VT8), just upgrading the BIOS version to the latest version can be solved. Note: Although the SATA hard drive itself does not have a master from the master, if you use a port mapping mode, when you want parallel your hard drive and serial hard drive, you still pay attention to the location of the hard disk or not conflict, and start the order It also needs to be adjusted according to the actual situation in the BIOS. The following is a GA-8KNXP Ultra as an example, briefly says that the Gigabyte motherboard is set in the BIOS setting: this motherboard chipset is I875P, the South Bridge is ICH5R, and its SATA section is set in the Main main menu, Integrated Peripherals under the main menu. Inside the peripheral device, the setting function is shown in the table below (only the part of the SATA hard disk settings): The options for the startup device are in the Advanced Bios Features, see the following table:
By two examples, you can see the motherboard of the ICH5 / ICH5R Bridge, which is set to identify the SATA hard drive through both port mapping and independent SATA channels. As for which mode and set value should be selected, refer to the above and according to the number of S-ATA hard drives and P-ATA hard drives, the installed operating system and which one as the system boot disk, and the like are set up. 2. The South Bridge is VIA's VT8237 motherboard relative to the ICH5 / ICH5R chipset, and the VT8237's SATA setting part is much simpler. The following is a STA-KT600 series as an example. The setting options in the SATA section are also in the main owner's Integrated Peripherals (integrated peripheral): Onboard Pata IDE (Motherboard Built-in Parallel IDE Set) This setting Allow users to configure the motherboard to build a parallel IDE function. Disabled: Turn off the parallel ID of the motherboard. Enabled: Allows the use of parallel IDE port functions (preset values). Onboard IDES OPERATE MODE (Motherboard Built-in IDE Priority Setting) PATA IS PRI IDE: Device priority (default) on the PATA port. SATA IS PRI IDE: The device on the SATA port is preferred. Onboard SATA- Ide (Motherboard Built-in SATA Function Setting) Disabled: Turn off the SATA port on the motherboard. SATA: SATA port on the motherboard is used as a general SATA port. RAID: The hard disk on the SATA port on the motherboard can establish a disk array (preset value). Here you only need to adjust a string according to the actual situation, and the priority of the parallel port can use the SATA hard drive. (From the above option, it can be understood here that the S-ATA hard drive can be understood as being mapped to the P-ATA port.) Note: The establishment of RAID needs to press "Tab" to enter VIA Technology RAID control while powering. For additional settings for the BIOS setting screen, see the relevant instruction manual. Second, the partition of the SATA hard drive is now generally used with FDISK, DM, PQ and other tools to partition with FDISK, DM, PQ after starting the program. Then just set it correctly in the BIOS and you can identify the SATA hard drive after startup, the partition of the SATA hard drive is exactly the same as the partitioning method of the traditional parallel hard disk. If you use the Win2000 / XP / 2003 launching CD to start and partition, if your SATA hard drive cannot be identified, then you need to prompt "Press F6 if you need to install a third party scsi or raid driver ... "Press F6 when you press F6, load the driver with a floppy drive, which is exactly the same as the traditional parallel hard disk partition method after the hard disk is correctly identified. Note: Some motherboards are not included with the drive floppy disk (such as the South China K7S8XE , using the SiS748 SIS964 chipset), and its driver does not copy directly from the disc directory to the floppy drive, but use the motherboard disc to be installed, please carefully Read the motherboard instruction manual. Third, the installation of the operating system 1.Win98 / Me No matter what chipset you are using, as long as you set it correctly in the BIOS and let the motherboard identify the S-ATA hard drive, then it can be installed normally. (Note: Of course, it has to be noted that Win98 / ME and other systems can only support 4 devices.) 2.WIN2000 / XP / 2003 and other NT core systems Here, because ICH5 does not need to load the RAID module, it can be installed directly (in fact That is to map S-ATA to the P-ATA port, naturally, it is the same as parallel hard drives). The ICH5R Nanqiao controller is divided into two situations. One is to completely block the RAID module in the BIOS, then the case is the same as ICH5, directly installed; the second is to open the RAID (Bios is open in the Bios At this time, you need to press F6 to load the drive when starting.
For the VT8237 theory, it should be similar to ICH5R, and most of the motherboard instructions also indicate that only as a normal SATA hard disk is used, it is not necessary to load the drive (such as Shuke's SL-KT600-R), but in fact regardless of the RAID function Need to load the drive. Because the author is limited, I don't know if it is, I also ask the reader to try it. Note: Other S-ATA controllers are currently except for the S-ATA controller that comes with the South Bridge, and some motherboards support the S-ATA from the South Bridge to support third parties such as Promise. -Ta and RAID controllers, please pay attention to distinguish. Fourth, the installation of the operating system is installed when the operating system is installed, and the corresponding driver needs to be further installed. 1. iCH5 only needs to load the INF drive provided by Intel. 2. ICH5R In addition to the INF drive, load IAA3.0 or above drivers. 3.vt8237 The VIA Hyperion 4-In-1 patch is required to install. If you also use parallel hard drives, it is best to use VIA IDE MiniPort Driver drivers that use VIA independently, which is likely to decline the burst transmissive rate of parallel hard drives, but has no effect on serial hard disk performance. Note: If you are using a third-party SATA control chip and RAID module, you also need to add the corresponding driver. Summary Through the above, the key to the S-ATA hard drive is to properly set the identification method in the BIOS, and because the BIOS menus of the motherboard manufacturers are different and the language manual is unknown, they have caused the S-ATA hard drive. Various problems in use. Due to the difference in R & D capabilities, you must want the motherboard manufacturer to make this part of the part. This is unrealistic, so the author only hopes that the reader can solve the problem according to his own actual situation. I wish all friends who use the SATA hard drive to use their SATA hard drive clearly. Easily teach you SATA hard drives greater than 137G
The previous 28 ATA specification limits the hard drive to 65536 × 16 × 255 × 512 = 131GB, according to the algorithm of the hard disk manufacturer is 137GB, which obviously affects the use of greater than 137GB hard disk users. However, if the motherboard supports 48-bit LBA addressing to support 137GB of hard drive, most new motherboards support new specifications. The following is a South Bridge chip that supports this specification: Intel ICH / ICH2 / ICH4 / ICH5, VIA VT8233A / 8235 and later, SIS 961 and later. With these Nanqiao chips, you can support large-capacity hard drives as long as you refresh the BIOS. If you can't determine if your primary version supports 48-bit addressing, the easiest way is to use "Intel 48-Bit LBA Test Program" (INTEL's test program detection 48-bit LBA test program), it can detect whether the motherboard BIOS support 48-bit LBA addressing method, determine if your motherboard BIOS supports 137GB of hard drives. Here download. The 48-bit ATA new specification, supports hard drives up to 144155188GB, but is only supported by the current 32bit operating system, which can only support 2200GB.
Common operating systems, such as Windows 98, Windows Me, Windows 2000, Windows XP, etc. By default, 48-bit LBA support is not enabled, no 37G hard drives are supported. According to Microsoft: At the same time, the following requirements can be met to use 137GB of hard drives correctly: must have 48-bit LBA compatible BIOS, must have a hard disk having a capacity of more than 137GB, and Windows XP or Windows 2000 must be installed. However, in actual use, there is a lot of trouble. If you use the operating system, you may cause the data loss, I am because I don't pay attention to the installation of the patch, resulting in all the amount of data over 137GB, Below is my hard experience. It takes 3 steps to use 137GB of hard drives: upgrade BIOS or set CMOS to enable SATA channel; clever partition avoid unnecessary trouble; install system patches to ensure data security. The following is a hard drive in Seagate's SATA160GB, 865PE motherboard as an example. The 865PE motherboard is equipped with Intel's own ICH chip to integrate support for Serial ATA, which should be stable. Open the motherboard to discover the first question: There is no SATA hard drive power supply line! The SATA hard disk interface is different from the IDE hard drive. Motherboard vendors may only provide SATA hard drive data cable without providing SATA hard drive power cords. First meet them: ordinary P4 power does not have a SATA hard disk power supply joint, users only find ways. Method One is to purchase power supplies for SATA power supply connectors, such as rock 355 power supplies, provide 5 IDE power connections, 1 SATA power supply joint, compatible with ordinary IDE hard drives and SATA hard drives. I use a variable method to purchase a pitch, one head is connected to the ordinary P4 power supply, and insert the hard disk interface. Remind DIY Don't forget the root power transfer line when you buy a hard drive. The SATA hard drive is strictly powered by the power supply. It is best to purchase a SATA hard drive. It is best to match a powerful power supply, and the interface of the hard disk is preferably connected separately, do not follow other devices. Avoiding a hard disk reading data is slow, and even if you don't recognize your hard drive.
Step 1: Set the CMOS to enable SATA channel 865's primary version to support 137GB of hard drives, do not need to be upgraded, but not you can use the SATA hard drive, BIOS only has 2 channels of IDE, you need to enable SATA channels in CMOS. Enter On Chip Device, the bottom is about SATA settings, ON-CHIP Serial ATA supports 4 settings: Disabled) ENHANCED MODE can only use traditional first channels on Windows2000 / XP system (For primary) When using the first passage, the first channel cannot use the Ide hard disk device for Secondary. When using the second channel, the second channel cannot be used to secure the AGP / PCI frequency when using the IDE hard disk device. Standard 66 / 33MHz. The SATA hard drive is very sensitive to the AGP / PCI frequency. If the AGP / PCI frequency is too high, it is very likely that the hard disk will appear. Save the settings, you can see that the home version correctly shows the SATA hard disk parameters, indicating that the BIOS supports a large-capacity hard disk over 137GB.
Step 2: Smart partitions to avoid unnecessary trouble I once picked this question in a famous IT Forum, it is recommended to have a lot: DM, PQ has FDISK. Try: Use the Windows 98 boot disk to start the machine, enter DOS, first fdisk, the problem has occurred, the capacity is less than 55g, you have to exit. With Windows Me's boot disk (version 4.9.3000), FDISK can display capacity correctly, it seems to be partitioned. But don't want to use fdisk because it is too slow. In addition, I have found an interesting phenomenon: the format command cannot correctly display the size of the partition or logical drive of 64GB. When you use format.com to format a partition or logical drive greater than 64GB bytes (or 68, 719, 476,736 bytes), format.com is incorrect in the formatting process. . However, as the formatting process continues, the entire hard disk will be formatted, and when the operation is completed, the formatted size will be displayed correctly. The reason is that Format.com will use some 16-bit values internally to calculate the originally displayed drive size, and some of these variables will overflow when the drive size is equal to or greater than 64GB. For example, if the partition or logical drive is 70.3GB (75, 484, 122, 112 bytes), the Format command initially reported the drive size of 63 GB (6,764,579,840 bytes). This is just a problem of display, that is, it is a surface problem, the hard disk will be formatted to its complete size. For DM9.56, you can correctly identify the hard disk capacity, but you don't dare to use it. One netizen uses the motherboard that supports 137GB of large hard drives in itself, and the consequence is: the 160G or 250G hard drive can only be used as 137G. The lesson of blood, one 160g is therefore a disabled 137GB. However, it is recommended that someone uses DM partitions and is used normally. The current relatively practical method is to start with the Windows XP disc, and then establish the system area according to the prompt first, install the XP system, and the remaining space is temporarily regardless of. Go to Windows XP, first install service pack 1, then use Windows XP Disk Manager to partition, fast, safe and reliable. Log in as a member of the administrator or Administrators group. Click Start, click Run, type CompMgmt.msc, and then click OK, in the console tree, click Disk Management.
1. To create a new partition or logical drive on the basic disk, follow these steps: (1) In the Disk Management window, complete one of the following steps, then continue step 2: To create a new partition , Right-click the unassigned space on the basic disk you want to create, and then click New Disk Partition. To create a new logical drive in the extended disk partition, right-click the available space on the extended disk partition you want to create, and then click New Logic Drive. (2) In the New Disk Partition Wizard, click Next. (3) Click the type of partition you want to create ("Primary DV Partition", "Extended Disk Partition" or "Logic Drive"), and then click Next. (4) Specify the size of the partition in the Size (M) "box, and then click Next. (5) Decided to manually assign the driver number, so that the system automatically enumerates the driver or does not assign the drive letter for the new partition or logical drive, and then click Next. (6) Specify the formatting option to use by using one of the following steps: If you don't want to format the partition, click "Do not format this disk partition", and then click Next. If you want to format the partition, click "Format this disk partition below", then complete the following steps in the Format dialog box: a. Type a name for the volume in the "Volume" box. Please note that this is an optional step. b. Click the file system you want to use in the File System box. You can change the disk assignment unit size, then specify whether to perform fast formatting, or specify whether file and folder compression is enabled on the NTFS volume. Click Next. Confirm that the selected option is correct, then click Finish. This creates a new partition or logical drive that appears in the corresponding basic magnetic disk in the Disk Management window. If you select the formatted volume in step 6, the formatting process is now started. 2. To format the partition, logical drive, or basic volumes, follow these steps: (1) In the Disk Management window, right-click the partition or logical drive you want to format (or reformat), then Click Format. (2) In the Format dialog box, type a name for the volume in the "Volume" box. Please note that this is an optional step. (3) Click the file system you want to use in the File System box. If you prefer, you can also change the disk assignment unit size, specify whether you perform fast formatting, or specify whether file and folder compression on the NTFS volume. (4) Click OK. (5) When you are prompted to format the volume, click OK. The formatting process will be started. 3. To view the properties of the partition or logical drive, follow these steps: (1) In the Disk Management window, right-click the desired partition or logical drive, and then click Properties. (2) Click the appropriate tab to view the appropriate properties. 4. To delete a partition or logical drive, follow these steps: (1) In the Disk Management window, right-click the partition or logical drive you want to delete, and then click Remove Partition or Delete the logical drive. (2) When you are prompted to delete a partition or logical drive, click Yes. This partition or logic drive is deleted. When you delete partitions or logical drives, all data on the partition or logical drive will be deleted with partitions or logical drives themselves; you cannot delete system partitions, boot partitions, or partitions for page (exchange) files containing events; unless The extended disk partition is empty, otherwise the extended disk partition cannot be deleted. Before deleting the extended disk partition, you must delete all the logical drives in the spread disk partition. 5. If your partition is less than 2G, even if you choose a FAT format, the system automatically turns into the FAT32 format when formatted. If your partition is greater than 32G, the system will automatically format the NTFS format.
Step 3: Timely install the system patches to ensure that data security is commonly used, such as Windows 98, Windows Me, Windows 2000, Windows XP, etc. By default, 48-bit LBA support is not enabled. If your BIOS does not support 48-bit LAB addressing, install the operating system in the first partition, and less than 137GB. 1. For XP systems (1) First Installing Service Pack 1 Only 48-bit LBA support is only enabled after Service Pack 1 (SP1) installed in Windows XP Home Edition or Windows XP Professional. Manually enable 48-bit LBA support in Windows XP installed in SP1 may result in data loss. My hard drive is because the data is lost due to the installation of the SP1 patch. (2) Secondly modify the registry launch "Registry Editor" (regedt32.exe). Find and click the item below: HKEY_LOCAL_MACHINE / SYSTEM / CURRENTCAL_MACHINE / SYSTEM / CURRENTCAL_MACHINE / SYSTEM / CURRENTCONTROLSET / SYSTEM / CURRENTCONTROLSET / SYSTEM / CURRENTCONTROLSET / SYSTEM / CURRENTCONTROLSET / Services / Atapi / Parameters / In the Edit menu, click Add Value, then add the following registration value: Value Name: EnableBiglba Data Type: REG_DWORD Value Data: 0x1 Exit "Registry Editor". (3) About the old version of Windows, if the old version of Windows that does not support 48-bit LBA is installed in the disk partition, and the partition is previously an operating system that can identify 48-bit (eg Windows XP, which occupies more space or exceeds the current 137GB of addressable restrictions, may have destroyed data. If 48-bit ATAPI support is enabled in the registry, there is a hard disk having a capacity of more than 137GB, but there is no 48-bit LBA compatible BIOS, only the first 137GB of the hard disk is addressable. The rest of the hard disk cannot be used. (4) Checking the version of Atapi.sys has an interesting phenomenon. Even if the patch of SP1 has to check the version of Atapi.sys, because only 5.1.2600.1135 version (or 5.1.2600.1152 for Windows XP 64-bit Edition) 48-bit LBA can be fully supported. The 5.1.2600.1135 version is launched after the SP1, this file is in the patch of 331958. The operating system is updated in a timely manner for your data security.
2, for Windows 2000 system first install Service Pack 3, although Microsoft said that you can support 48 LBA addressing after installing SP3, but repeatedly emphasizes the update of your operating system to the latest patches. Secondly modify the registry, operate the same.
Don't buy a mobile hard drive, let SATA hard drives move
As we all know, the SATA hard drive is relatively simple in terms of performance, and the hardware connection does not support the hot-swap function that is not supported in parallel IDE hard drives. And the SATA interface data transmission speed is up to 150MB / s, which is more appropriate to do external mobile hard drives. Here, there are several options that allow SATA hard drives to move: 1.SATA special extension bezel actually, now there is already a motherboard manufacturer to think of this, and come with SATA extension baffles in the sold motherboard, such as: Gigabyte GA- 8PENXP provides a feature extension bezel called "GC-SATA" that extends the two SATA interfaces on the motherboard to the baffle through the transfer line to facilitate an external SATA hard drive. On the baffle, a D-type power supply port is provided, which can be matched with the dedicated power transfer line of Gigabyte. This power cable has a SATA power interface and a D-type power interface, plus a D-type SATA power cord. Can supply two SATA hard drives. This design uses the SATA hard drive to facilitate the feature of hot-swapping, allowing users to use the SATA hard drive as an external hard drive. (Figure 1) Advantages: low cost, easy connection. Disadvantages: There is no box protection in the hard disk, and the security is low. And there is only a very small number of luxury i865 or i875 motherboard distribution, such as Gigabyte, $ 2,000! If you don't plan to buy this motherboard, spend more money for a piece of baffle so much money. Of course, there will be such a single extension bezel on the market, and it is very cost-effective. 2. SATA internal connector (Figure 2) SATA external hard drive (Figure 3) (user with SATA interface on the motherboard) or SATA PCI extension card (Figure 4) SATA external hard drive Box (user without SATA interface on the motherboard)

These two baffles have 2 interfaces (of course, there are only 1-interface product), with 2 SATA external hard disk boxes, can even set up RAID, and can be hot, in RAID mode, if a hard disk occurs Damage, you can also realize the heat replacement hard drive. Advantages: high function, high stability and safety. Disadvantages: High cost, the price is nature is not low.
3 .. Built-in SATA hard drive extraction box (Fig. 5 and Figure 6) The rear panel of the box has a standard SATA cable plug and a 4-pin power connector, so that when using these boxes, There is no need to use a dedicated SATA power cable. Advantages: Simple installation, but also safe. Disadvantages: Specially designed for SATA hard drives, no SATA to IDE converters. If the motherboard does not have a SATA interface, you need to match the PCI extension card of Figure 4, using the built-in interface provided on its card. All of the above three programs have their own advantages and disadvantages, and everyone can choose from must choose according to their own actual situation, let your SATA hard drive move!

Storage Market Brand SATA Hard Disk Buying Products
Mainstream Serial ATA Hard Drive Comments Currently, Maxto, Western Digital, Samsung, and Hitachi and other major manufacturers have batch SATA hard drives. Here, we introduce the products of each brand, allowing you to have a reference for reference before intentionally upgrading to the Serial ATA hard drive. 1, Seagate Barracuda SATA V series, Compared to other manufacturers, Seagate's Cool fish v SATA products are the earliest desktop SATA hard drives in the market. Although their single-disc capacity, motor control, SATA support is implemented through bridge mode. Parameters, performance is not satisfactory, but as the first cannon of the desktop SATA hard drive to the market, it is obviously important for important guidance. Later, I quickly launched its native SATA hard drive-Barracuda 7200.7 Serial ATA hard drive, and quickly received the market accepted by excellent performance. Barracuda 7200.7 Serial ATA hard drive supports the so-called Serial ATA native command queue mechanism, similar to the SCSI instruction queue, the difference is that SCSI supports 256 queue classes, while the Serial ATA protocol command queue technology supports the 32-class command queue mode, allowing Serial The ATA hard drive can re-scheduled the inflow instruction, and the data is sent back to the host after accessing the data. Seagate The earliest SERIAL ATA hard drive mainly has two mains, and recently launched a model with a capacity of 160GB. Fully follow the capacity demand of the mainstream market. The product is available ... From the look, the hard disk body is complete with metal. Protect and apply the product description separately. Seagate Barracuda 7200.7 SERIAL ATA hard disk number is composed of 4 parts: ST, Seagate Technology company's English abbreviation; The unit is MB, such as 160GB type, indicates 160023; AS, represents the hard disk interface specification, AS represents Serial ATA. On the back of the hard drive, the power supply and transmission line picking method in the back of this hard disk are described in detail, plus the two wirings itself has a stretch function, so the chance to get the wrong, and the output of the main body / In the interface part, this hard disk is quite simple to provide the interface of the Serial ATA. Now there are many main boards of the Built ATA feature, providing the transfer line of the Serial ATA with the IDE 12V power supply, so don't worry that the power is not supported. 2, Maxtor Diamondmax Plus 9 Series

Since IBM sells all its hard disk departments to Hitachi, all IBM hard drives have become a Japanese logo, actually before IBM hard drives are also partially responsible for Hitachi. At present, Hitachi hard drives on the market have mainly 180GXP series and 7k250 series. Among them, the 7k250 series is the first "new" product that is officially launched after the IBM hard disk is acquired. Deskstar 7k250 series desktop hard drive single disc capacity is 80GB disc, mainly added to LOAD / UNLOAD (head load), Tag and seek, eddy current latch (eddy hexagle lock) These three technologies have helpful to the earthquake resistance, stability, and failure rate of the disk. Moreover, the disc group is also over the past glass disc, which is more cost-to-cost, and more secure aluminum disc. At present, there are 4 serial versions in the Deskstar 7k250 series, with capacity from 80-250GB.
Hitachi serial hard drives are also bridged SATA hard drives, which also uses the exact same main control chip with parallel hard drives, and also uses 88i8030 bridging chips. The Deskstar 7K250 series hard drive is controlled in noise levels and fever indicators. In terms of proxy, Hitachi's rights, new resources, and Weijian three as the agent of Hitachi hard drives, SATA hard drives are treated by 8MB cache, so warranty is 3 years. 4. Western wast wd *** JD series, the wisdom of 7200 rpm desktop serial hard disk belongs to the WD Caviar SE series, indicates the "JD" suffix (Note: Parallel version with "JB" as a suffix), a total of 5 Product: WD800JD (capacity is 80GB), WD1200JD (capacity is 120GB), WD2000JD (capacity is 200GB) and WD2500JD (capacity 250GB).
