The hard disk cannot start a fault

I am adjusting the partition with the PQMAGIC 3.04, because PQMAGIC 3.04 cannot adjust the size of the FAT32 partition greater than 2G, the middle is failed, and then uses the backup partition table to recover the system, but the system restarts StartingWindows 95 ... After it is now, No other display; change the machine start order to A, and then start with emergency rescue floppy disk, showing Starting Windows 95 ... After the hard disk indicator is on, it is the same. After turning off the hard disk in the CMOS setting, use the floppy disk normally, so the floppy disk is impossible to damage; the hard disk just used less than a month, it has been normal, it will not be damaged. After a day, I held the lucky psychology, put the low version of the DOS 3.3 boot disk into the A driver, the miracle happened, the machine was mysteriously started, and showed the proven prompt c. : /.

After careful analysis, it finally found the reason. It turned out to be a disk compression profile in the monster. When the configuration file DBLSPACE.INI in the C: /, the floppy disk and the hard disk can be started normally when setting the DBLSPACE in the msdos.sys file, and these two The profile is not used by DOS 3.3, so DOS 3.3 can start normally. The deep reason is that the partition adjustment of the failure disrupts the information of the D partition, and when the hard disk has a compressed disk, the DOS is started to scan all hard disk root directories according to the compression disk profile, find the compressed disk volume file, and install these compressed Disc, when searching D partition, due to the damage of the boot sector, the machine enters the dead cycle and crashes. The reason is identified, and the D partition is advanced with Format and then restores the compression disk configuration, everything OK.
