Doscommand-based hard drive bad track detection and repair tools

Try to fix the system first. Please refer to the following article! How can I fix bad hard drive channels? First, check whether the hard drive's bad track is a logical or physical bad track. The method is very simple. Press "F8" when the computer is started and select "command prompt only" to enter the DOS mode. The operating system of this method must be Windows 95/98. If it is Windows 2003/XP/, use the DOS boot disk to start it. Then run "Scandisk X:" (X indicates a drive letter suspected to be faulty). Scandisk checks the hard disk and automatically displays a dialog box for the generated logical Bad Sectors, select "fix it" to repair the logical bad track. If the scanning program is stuck at a certain stage, the hard disk has a physical bad track. If a hard disk with a logical bad track still exists in the initial repair process, go back to Windows after normal startup, go to "my computer", select a partition with a logical bad track, and right-click it, select "attribute", "tool", and "Start Check". The "disk scan program" is displayed, select "complete", and check "Automatic repair error, click Start to scan and repair the partition. The above method is useless for hard disks with physical bad channels. For such a fault, if the hard disk has not been warranty period, go to the seller for replacement or repair. However, if the warranty period expires, you can repair it by yourself. We recommend that you use the original DM tool to "clear" the hard disk and solve many minor problems with DM, after the above processing, the hard disk repair time can be greatly shortened by using other software. Then use hddreg, mhdd, and Fb software for processing. These software functions are similar and have different features. Hddreg can achieve the goal of Repairing Bad channels through magnetic reversal. It is said that it can repair about 60% of damaged hard disks without affecting the original data information of the hard disk, this is what low-level formatting programs cannot do. Of course, you can also use partition magic for manual processing to hide bad channels. The specific method is: first start partition magic, select the "check" command under the "operation" menu, scan the hard disk directly, mark the bad cluster, select "advanced" and "bad sector retset" under "operation", divide the bad cluster into independent partitions, and then use the "Hide partiton" command to hide the partitions. If the computer prompts "track 0 bad, disk unusable", it will be troublesome to fix it, because this information indicates that the hard disk is damaged by zero magnetic channels, most people simply decompress the hard disk. But it cannot be repaired. The principle is very simple. You only need to use one sector to replace the zero sector. Here we recommend "diskman", a commonly used hard disk tool. Run the command in pure DOS after downloading. The method is as follows: select the disk to be repaired (usually the C disk) in the "Hard Disk" menu ), go to "Tools" and "parameter modification" in sequence, change the value of "Start cylinder" from "0" to "1", and save and exit. You can partition the hard disk. At present, the professional hard disk repair software "PC-3000" and hard disk manufacturers of the repair method is very similar. PC-3000 is a commercial professional hard drive repair integrated tool developed by Ace laboratory, a famous Russian hardware laboratory. Through analysis and reverse engineering, it can crack the manufacturer's instruction code or even firmware, so that program software can be compiled to read, modify, and write the information of the hard disk system information zone freely. Like hard disk manufacturers, write programs to scan the disk surface according to the physical address, and reconstruct a new list of defective sectors to be written into the system reserved area to replace the original list. Hard Disks repaired by such software are theoretically basically the same as hard disks repaired by hard disk manufacturers.
