Users questions: Recently the computer starts is always an unknown error. Or start half-way crash appeared. Prompted: stop: c000021aunknownharderrorunknownharderror take measures beyond ineffective. Measures taken include: checking the motherboard Plug-ins, including memory; replacement hard drive, optical drive, battery; re-install the system files XP; virus; download and install a system update patches; and so on. Is to do nothing. Who can help me? Another phenomenon: When the stop: c000021aunknownharderr orunknownharderror prompted, restart does not work.

Experts answer: on the lead to stop: c0000 21aunknownharderror part of the problem and solution. 1. Installed when the stop: c000021aunknownharderror few days ago I formatted assembly is not on the plane, I first of all pure DOS format exclude viruses and software conflicts, hard drive Track inspections are nothing still not installed, and later found to cause some damage to installed capacity of installed CD-ROM file does not complete due to re-new system for Zhang disk problem has been solved. 2. Unknown track error or unknown hardware error occurred before this problem we first confirmed that the first track check hard disk bad sectors is a logical bad sectors or goods Management bad sectors, is simple. Just start the computer, press the "F8" key, select "CommandPromptonly" into the DOS mode (OS must be Win95 * 98, if the Win2000 * XP, use the DOS boot disk), the implementation of "sca ndiskx: "(X is the drive letter), Scandisk program will check the hard disk, and on the logical bad sectors on their own pop-up dialog box, select the" Fixit "for primary repair logical bad sectors. such as the scanning process at a stagnation in progress the former, then there will be a physical bad sectors hard disk. for already Initial repair the hard disk is still the logical bad sectors, after the return to normal Windows, boot into "My Computer" select the logical bad sectors in hard disk, click the right mouse button, select "Properties" "Tools" " Start Check "on the pop-up" ScanDisk ", select the" full "and" self- Activity fix error "check mark click" Start "and started to scan and repair the partition. As for a physical bad sectors of hard disk, the method can not do anything, but not without means. Face I used to introduce a kind of "PartitionMagic" (partition magic, hereinafter referred to as PM ) Method of repairing the hard disk. Through the re-partition the hard drive, hidden physical bad sectors of hard disk space, its segregation. Specific approach is: first of all start the PM, select the "Operations" menu under the "Check" command, a direct scan on the hard drive, bad clusters marked, the selected "Operations" menu under "Advanced" "badsectorretset end to the bad cluster into a separate partition, and then through the" Hidepartiton "command will be hidden partition, thus you're done. Track damage occurs stop : C000021aunknownharderror zero track the problem more generally this happens, most people put hard disk to discarded. But not absolutely can not be repaired, the principle is very simple, as long as the sector with a sector instead of 0 on the line this time, please "DiskMan" to help Help us, it is a tool commonly used hard drive, we can Free Software *** (bj.onlinedown.net). *** After the run in pure DOS, in the "hard" menu, select the disk you want to modify (usually C drive), and then turn into the "Tools" "parameter Modify " to" start cylinders "value from" 0 "to" 1 "to determine the exit after the save. You can re-partition the hard disk. If a problem arises after the above method not work, it had to use the ultimate Dafa - low-level format check all hardware installed no problem, have not changed the parameters: 2 . Computer Off When STOP; c000021aunknownharderror (software conflict) can not find your windowsXP closed, it can not reboot, because my XP to disable the "serious mistake if the automatic restart", so every time
