Common failures and quick fixes for hard disks

As we all know, hard disk in the computer parts of the position is important, hard disk failure will certainly affect the normal use of users, some of which are more troublesome, today small set will share with you: Hard disk "hard drive logic lock" and the hard drive parameters of the solution, I hope to you useful. Camera failure

1. Hard Drive "logic lock" fault office software

The "Hard drive Logic lock" is made from a bug with some dos. It uses the "cyclic partitioning table" technology, so that some of this error dos can not be started with any device, including floppy disk and other mobile devices. When DOS starts, the system will automatically search the hard disk of the various partitions of information, such as type, size, etc., so that the system can identify the hard drive, respectively, assigned to C, D, E, F and other drives, and enable users to carry out a variety of operations. and "logical lock" is the use of this point, by modifying the partition table of the hard disk to make the partition table loop, that is, the first logical disk of the extended partition point to itself, so that some DOS system start to find the partition occurs when the cycle of death loop and can not start.

Fault performance

When your hard drive has been "logically locked" by some malicious programs, you will find that the hard drive can not boot, and try to use the CD-ROM, floppy boot system is not good, or even remove the hard drive as from the disk to other computers still can not boot the system, but in the BIOS can easily view the hard disk information.

Solutions

For the removal of the hard drive logical lock method is different, here we introduce a relatively simple and practical. First of all, a prior to do a floppy disk containing DM program inserted into the floppy disk, and then enter the BIOS, the hard drive parameter set to "None", so you can boot from the floppy disk into the DOS operating system, running the DM program on the floppy disk, where the hard disk partition and implementation operation. The operation completes again enters the BIOS to change the hard disk the setting, thus may solve the hard disk "the logic lock".

Small skills: is the so-called "art Man bold", here we introduce a more simple operation, open the chassis to remove the locked hard drive power cord, and then boot from the floppy disk, start and then "Hot plug" on the hard disk power cord, so you can enter the hard drive to operate. As the method is very dangerous, only as the conventional method is ineffective, only hold the "crash right when the live horse medical" idea and implementation.

2. Repair HDD Parameter Error setting

Fault performance

"Device error" appears on the screen while the computer is starting, then prompts "Non-system disk or disk Error,replace and strike any key when ready", after trying to start with a floppy disk, execute C:, Prompt "I Nvalid Drive Specification ".

Fault resolution

It is possible to judge from several error messages that the hard drive setting parameters are missing or the hard drive settings are incorrect in the CMOS. To solve this problem is also more convenient for the comparison of new computers, directly into the CMOS, select "HDD Auto Detection", which will automatically detect the relevant parameters of the hard disk, and for those who do not have hard disk detection in the CMOS items of friends, you need to see the relevant parameters of the hard disk , and then manually modify it.
