Hard disks are the most important storage media in your computer, regarding hard drive maintenance, I believe that each computer user knows. However, many of the previous articles are a single-machine user in the dial era. It is gradually popular in broadband. Today, the big hard disk is continuously cut. Many people will make the hard disk full load: watch high-definition DVDRIP movies, do not interrupt BT download, using Windows system restore function ... However, you may not be clear that the new application models bringing these new software will bring new damage to the hard disk!
The hidden danger brought by the new application mode
1. Code error DVDRIP
It is now quite popular with the movie of DVD transcription compressed DVDRIP format. This format of film clarity and DVD are different, but downloading a movie is only 700Mb ~ 1.3GB size, so many users like to download the movie in the DVDrip format to the hard drive. However, playing this format movie has a high requirements: in addition to the CPU, the graphics requires strong enough to ensure that the play is fluent, the hard disk load is also very large - because playback DVDRIP is a continuous decoding decompression, then transport to display The process of the system. The author found that when there is a DVDRIP file with an encoded error, Windows will have a very high disk occupancy: the system is constantly converting the encoded into a video signal, but the encoded error file index and the corresponding signal segment do not match - At this point, the hard disk light will flash continuously, and the entire system responds extremely slow to the user, and the user clicks on the menu but there is hard to react. If the code is more incorrect, the system sometimes even crashes. Many users are very impatient at this time, directly pressing the reset button on the chassis or even directly shutting down the computer power supply, this operation is quite dangerous without normal reset in the hard disk head!
Tip: User users in Windows XP need special attention, when we automatically preview some files in Windows XP, although there is no formal play, there is no formal play, but the computer speed suddenly slows, the hard disk light is constantly flashing Other phenomena, the culprit is still a video file error code!
2. BitTorrent download
BitTorrent download is a broadband era emerging P2P exchange file mode, and all users share resources, mutual seeds and relay stations, commonly known as BT download. It is almost simultaneously performed by the download and upload of each user, so the speed of download is very fast. However, it will directly write the downloaded data into the hard disk (unlike the next to the next-load tool such as flash Get, it can be used to write the hard disk after the specified amount of data), so the occupation of the hard disk is much larger than the FTP download!
In addition, BT is downloaded in advance to apply for a hard disk space. When downloading larger files, there will be a task of all system priorities for 2 to 3 minutes, and other tasks are extremely slow. In order to make full use of bandwidth, some BT download tasks will also be made at this time, it is very easy to have crash failures due to excessive disk occupancy.
Therefore, unless your computer hardware configuration is quite high (especially memory, at least 256MB or more), otherwise, before BT download, if you want to perform long, multitasking download applications, it is best to use traditional FTP software .
3. Danger of pqmagic conversion
Pqmagic is a famous partition magician that can freely adjust the partition size and format without damaging the data. However, when pqmagic has just launched, the general user's hard drive is about 2GB, and now 60 ~ 80GB hard drive is everywhere, pqmagic is not from the heart: adjustment with data, 5 GB of partitions, usually need 1 Hours or more!
In addition to the impact of capacity factors, PQMAGIC adjusts the hard disk partition, which spends a lot of time on the check data and detects the hard disk. It can be seen that in this case, "lossless partition" is difficult: due to the speed of the conversion Slow, time-consuming too long, the conversion adjustment process is easy to cause data loss due to factors such as computer power failure, crash. This loss is usually one or several partition missing, or the capacity becomes abnormal, and even when it is severely, it can cause data from the entire hard disk. 4. Abnormal caused by hard disk protection software
It is easy to cause hard disk abnormal, and there is hard drive protection software. For example, "Restore the Elf", because many people don't pay attention to the normal unloading of the system or re-partition, the system cannot be fully installed. At this time, I want to install and uninstall "Restore Elf", but the software has been installed and cannot continue, caught in a dead cycle. This failure is due to the "Restore Elf" take over the INT13 interrupt, controlled the hard disk boot before the operating system, and the FDISK / MBR instruction cannot be resolved. This is only the fault of the software, but many people have insufficient experience, and there is a problem that the "trial" of various partition tools will be "trial", and even the low level is low, under such a toss, the hard disk is likely to die in advance!
5. Frequently organized disk fragments
Disk Defragments and System Restores are the normal features provided by Windows, but if you frequently do these operations, it is harmful to the hard disk. Disk finishing should be based on the hard disk, determine which data can be moved, which data can not be moved, and then sort files. Before formally arrange the hard disk data structure, it continues to read the write data to other clusters. After the order is placed, the data will be moved back to the appropriate position, which will occupy a large number of CPUs and disk resources. In fact, for the current big hard drive, the proportion of space occupied by documents and emails is very small, and most people buy big hard drives are used to install movies and music. These partitions do not need to be tied frequently - because of the effects and disks of multimedia files The structure is nothing to do, and the playback speed is determined by the graphics card and the CPU.
6. Automatic restart of Windows XP
The automatic reboot feature of Windows XP automatically turns off the process of unresponsive procedures, which automatically exits the procedures for illegal operations, thereby reducing the user's steps. However, this feature also has a big problem: it will turn off the hard disk power before automatically restart, turn on the hard drive when restarting the machine! In this way, the hard disk is impacted twice in the time interval in less than 10 seconds, which is likely to have a sudden "death" failure. In order to save some energy settings to allow the system to shut down the hard drive, it is also harmful to the hard disk. This article is taken from: http://article.pchome.net/2004/10/15/28235.htm
