Hard Disk detection tool mhdd repair hard disk failure identification

Many times, due to misoperations, the hard disk may suffer from various faults. For example, if a machine crashes during the process of backing up zone C with ghost, the hard disk will not be detected after restart, at this time, you need to use the hard disk detection and Repair Tool mhdd. It is a free hard disk entity scanning maintenance program that directly reads all the physical sectors of the hard disk. Use mhdd to repair faults that cannot be identified by hard disks or hard disks. The procedure is as follows:

① Restart the system to enter the pure DoS Status and run the mhdd program. Mhdd first detects all hard disks in the system and provides the code and connection status of each hard disk. Enter the hard disk code to be detected, and then use the Command provided by mhdd to repair the hard disk.

② Execute the wait command of mhdd. If the command succeeds, the first hard disk head is good. Next, press F3 and F2. If any parameter is displayed, first enter the makebad command, and then use aerase to perform sector-by-sector clearing. The produced sector does not need to be too large.

③ If no parameters are displayed for F3 and F2, run the hddl20 program to read the firmware of the same hard disk model and then write it into the faulty disk. To ensure security, LDR files cannot be written to power-off. After the write is completed, the hard disk can be repaired.

④ Run mhdd, run smart on first, and then run smart AAS to enable the implicit switch.

⑤ Use scan to open remap (bad track re ing) for scanning, and the normal bad track can be fixed.

⑥ After the hard disk is repaired successfully, if a ghost error occurs again, it enters the pure DOS state, enter the fdisk/MBR command, and then enter the ghost-fdsz command (fdsz should be capitalized ), the fault will be ruled out.
