The track is in a very significant position, of hard disk advocate lead record division (MBR) be in this locally. The 0 tracks that MBR is located in hard disk 0 cylinder an area, depositing hard disk among them advocate bootstrap and watch of hard disk partition. Be in gross the hard disk of 512 byte advocate in leading record fan area, 446 byte belong to hard disk advocate bootstrap, 64 byte belong to hard disk partition to express (DPT) , two byte (55 AA) belong to partition to end a sign. This shows, once 0 tracks are damaged, will make of hard disk advocate bootstrap and divisional watch information are played havoc with, bring about hard disk to cannot be lifted oneself thereby.

0 tracks attaint attributes one of hard disk bad talks, just the position as a result of it is too significant, once suffer,destroy consequently, can produce serious consequence.

Normally maintenance method is the DE that passes Pctools9.0 (disk editor) come repair (similar perhaps it is OK also to can have editorial tool to disk fan area) , its method is as follows:

Start Pan Qi to move with Windows 9x, insert the CD that contains Pctools9.0. The De.exe below moving PCT90 catalog, enter first " Options " menu, choose " Configuration " (configuration) command, press " blank space " Read Only of key take out (read-only) in front tick off (by Tab key switch) , later, save exit.

Choose then and carry out entree sheet " Select " (choice) medium Drive (driver) , after going in, be in " Drive Type " (driver type) in, choose Physical (of physics) , press blank space make choice of, press again " Tab " key switch arrives " Drives " , pitch on " Hard Disk " (hard disk) , finally, choose " OK " and carriage return.

Later, in returning entree sheet, open " Select " menu, can appear at this moment Partition Table (divisional watch) , pitch on keeps abreast of, hard disk partition appears to express information later. If hard disk has two partition, l partition is C dish, this partition begins from the 0 cylinder of hard disk, so, the Beginning Cylinder 1 partition (initiative cylinder) 0 change 1 OK. After saving, exit.

Those who want an attention is, the important data backup that gets on hard disk first before revise comes out. Start afresh, by Delete key enters a CMOS setting, choose " IDE AUTO DETECT " , can see CYLS number decreased than before 1, later, save a setting and exit. New partition, format is changed, can hard disk of bring back to life.

Those who need an attention is: Because DE tool is opposite only the hard disk of FAT16 partition is effective, accordingly, for divisional to FAT32 hard disk, can pass divisional Great Master (PQ) wait for disk tool, FAR32 changeover is FAT16, undertake handling to its again next.

Additional, somebody returned exploration to go out to locate through revising hard disk electric machinery the system will change 0 tracks the position and adjust those who will change magnetic head to allocate logic through circuit, in order to obtain new fixed position the purpose of 0 tracks. Of course the hardware level with this deeper need, implementation rises more complex also.
