HDD 0 Track Repair method

The "0" track is in a very important position on the hard disk, and the main boot record area (Mp) of the hard disk is in this location. The MP is located on the hard disk's 0-track 0-cylinder 1-sector, which holds the hard disk Master bootstrapper and the hard disk partition table. In a total of 512 bytes of hard disk master boot record sector, 446 bytes belong to the hard disk master boot program, 64 bytes belong to the hard disk partition table (DPT), two bytes (AA) belong to the partition end flag. This shows that the "0" track once damaged, will make the hard disk's master bootstrapper and partition table information is severely damaged, resulting in the hard drive can not lift itself. "0" track damage also belongs to the hard drive bad, but because its position is too important, so once destroyed, it will have serious consequences.

1. The symptom after the hard disk "0" track damage

When the hard disk "0" track Damage: The system self-test can pass, but the boot, the partition is missing or the C disk directory is missing, the hard disk appears regularly "Creak ..." Creak "seek sound, run ScanDisk scan C disk, in the first cluster appears a red" B "; fdisk and other partition software can not find the hard disk, the use of the lower version of DM partition, the program" Dead "on the 0 track; When you Do" Format C: ", The screen prompts 0 tracks to damage or endlessly execute read command "Track 0 bad".

2. To solve the hard disk "0" track damage thinking

The head is always the "0" track as a reference point, if the "0" track physical damage, the head positioning mechanism will be unable to find "0" track, so that the hard drive failed to lift itself. Therefore, when solving the hard disk "0" track damage problem, generally take the "1 generation 0" approach, that is, when partitioning the hard disk, redefine the "0" track, the original "1" track defined as a logical "0" track, to avoid the damaged "0" track.

3. Through the tool software to solve the hard disk "0" track damage

Through the DM million version to solve

First download the DM million version from the Internet.

And make a good DM startup floppy disk (CD), and then execute DM and enter its main interface. In the main interface, press the ALT+M key combination into the DM advanced mode, position the cursor to the (E) dit/view partitions (edit/view partition) option, and after pressing ENTER, the program requires you to select the hard disk you want to repair, select the hard drive, and press ENTER to enter the partition view interface of the hard disk. As shown in the figure.

Select the "1" section in the partitioned list box, where the partition Information bar displays the partition information, such as partition format, capacity, start cylinder, end cylinder, and so on. At this point you need to remember the "0" and end cylinder ordinal "2489" in the start cylinder. Keep the cursor positioned on the 1th partition, and then press Del to delete the partition, select "Yes" and enter in the interface that confirms the deletion of the partition, and then the 1th partition is deleted.

Keep the cursor on the 1th partition, and then press INS to add the partition. Select the "dos-fat32" option in the partition type interface that appears, press Enter and then the key step to fix at this point-"Select Entry Mode" (Set capacity pattern). In this interface must choose the "(C) ylinders" (stigma) option, enter the input after entering the capacity of the interface. In this interface, the capacity is entered according to the cylinder surface. For the first partition (that is, C-disk), are starting from the 1th cylinder, but now we have to change the front of the "0" to "1", as for the end of the partition is not necessary to modify the number of cylinders, can be based on the number of the end of the 1th partition to fill.

After dividing the partition number 1th, return to the partition interface, position the cursor to save and Continue (save and continue) options, and then press ESC to launch DM, and then restart the computer as prompted.

After restarting your computer, first reset the hard drive parameters in the BIOS through the IDE HDD auto-detection feature, and then enter the format for the C disk. At this point, the repair work is over.
