The zero track is hard on a very important position, the hard disk master boot record area (MBR) in this position. MBR in the hard disk cylinder 0 track 0 sector 1, which holds the hard disk master boot program and hard disk partition table. In a total of 512 bytes of hard disk master boot record sector, the 446-byte belongs to the hard disk master boot program, 64 bytes belong to the hard disk partition table (DPT), 2 bytes (55AA) belongs to partition end marker. Thus, the zero track, once damaged, will the hard disk master boot program and partition table information has been severely damaged, leading to the hard disk can not be bootstrapped. All the best.

Zero track damage to belong to one of the hard disk bad sectors, but because of its location is too important, so once they are damaged, it will have serious consequences. The usual method is through the maintenance Pctools9.0 of DE (disk editor) to fix its methods are as follows: With Windows9x boot disk, insert the CD-ROM containing the Pctools9.0. Run PCT90 directory de.exe, entered the "Options" menu, select "Configuration" command, press the "space" key to remove ReadOnly in front of the hook (press Tab key to switch), followed by , Save and Exit. Then choose and implement the main menu "Select" in the Drive , go after the "Drivetype", in select Physical, and then select a space and then "Tab "key to switch to the" Drives "item, select" Harddisk ", and finally, select" OK "and press ENTER. All the best.

If the hard disk has two partitions, 1 is the C drive partition, the partition is started from the hard disk 0 cylinder, then it will be a partition Beginning Cylinder (starting cylinder) and 0 into 1 on it. Save, then exit. It should be noted that, before amendment, first backup important data on the hard drive out. Restart, press Delete key to enter the CMOS settings back to the election "IDEAUTODETECT", you can see the number of CYLS reduction than the original one, after which save your settings and exit. To re-partition, reformat the hard disk can be saved. All the best.

The hard disk master boot record virus, where the sector is also the focus of attack place, by destroying the main boot sector of the DPT (partition table), you can easily damage the hard disk partition information. In general, damage to the partition table is not a physical damage, but partition the data is destroyed. Thus, normally, you can use the software to repair. Under normal circumstances, after the hard disk partitions, backup a partition table to floppy disk, CD-ROM or USB drive is very wise. This respect, the domestic well-known anti-virus software, Rising provides a complete solution. In addition, there is no backup for hard disk partition table also provides the corresponding repair method, but the success rate is relatively low. Check and reply.

For the hard disk partition table has been adjusted partition software severely damaged, causing the hard drive and system failures, DiskMan through unspoiled partition boot record of information re-create the partition table. A tool in the menu bar, select "rebuild the partition table", DiskMan began to search for and reconstruction of partitions. DiskMan will first search cylinder 0 head 0 sector starting from the two hidden sectors to find the virus moving off the partition table. Next, search the first sector of each head. The search process can be used "automatic" or "interactive" two ways. Automatic discovery of each partition to retain suitable for most situations. Way interaction was found for each partition is given a prompt by the user to choose whether to retain. When the automatic renewal of the partition table is incorrect, you can use interactively to re-search. All the best.
