Maintenance and treatment of hard drive bad track

Even if the hard disk's daily use and maintenance is good, it is possible to produce bad way (many of the reasons, such as: hard disk quality problems, etc.). Once the hard drive appears bad, people do not have to panic, I have to identify and repair the hard drive bad way to tell everyone to help us tide over the difficulties.

The hard drive's bad road is divided into two kinds: logical bad way and physical bad way. The logic bad way is the soft bad road, mostly is the software operation and the improper use causes, can be repaired with software; physical bad way for real physical bad, it shows that the hard disk surface track on the physical damage, most of the software can not be repaired, only by changing the hard disk partition or sector of the use of the situation to solve.

Know the hard drive produces bad way principle, now let us look at the hard drive to produce the general phenomenon of bad.

When you open, run or copy a file, the program, the hard drive is slow, read the disk for a long time, and then error, or Windows prompts "unreadable or unable to write files," a blue screen phenomenon occurs when serious.

The hard drive reads and writes the sound from the original "Cha Cha" The Friction sound changes the strange sound.

The ScanDisk is run automatically every time you enter the system, or the red "B" Mark appears when the hard disk is scanned.

When the virus is excluded, the computer cannot boot from the hard drive when it starts. On the self-test, the screen prompts "Hard disk drive Failure" or "Hard Drive controller Failure" and similar information.

When the hard disk fails to boot, boot with a floppy disk, and information such as "sector not found" or "general error in Reading drive C" appears. There is a can go to the hard drive is the letter, but cannot enter.

When the hard drive is formatted, the progress is stalled and the last error is withdrawn.

To the hard disk with "Fdisk" command to partition, to a certain progress will be repeated into retreat, can not be completed.

If you are in the daily use of the computer in the process, the above situation or similar phenomenon, you should be careful, your hard drive may have been bad!

First of all, we first confirm that the hard drive is bad logic or physical bad way, the method is very simple. In the computer just started, press the "F8" button, select "Command Prompt only" into the DOS mode (the operating system must be win95/98, if for win2000/xp please use the DOS boot disk), the implementation of "ScanDisk x:" (X for the letter), The ScanDisk program will check the hard drive, the resulting logical bad way will pop-up dialog box, select "Fix It" to the logical bad road for primary repair. If the scanner is stalled at a certain pace, then the hard drive has a physical bad way.

For a hard drive that has been initially repaired with a logical bad path, after normal boot back to Windows, into the "My Computer" to select a logical bad hard drive, click the right mouse button, select the "properties" → tools → "Start check" pop-up "ScanDisk", select "Full" and "Automatically Fix Errors" Tick, click Start, and start scanning and repairing the partition.

And for the hard drive with the physical bad, the above method is powerless, but it is not no way.

The easiest way is, if the hard drive has not yet passed the warranty period, go to the seller, let it find a way (don't forget to bring the invoice). But if the warranty period or met the profiteers, they have to find a way, I would like to introduce a "PartitionMagic" (Division Magician, hereinafter referred to as PM) to repair the hard disk method.

The reason is very simple, through to the hard disk repartition, hides has the physical bad road the hard disk space, has carried on the quarantine to it. The concrete practice is: Start PM First, select "Check" command under "Operations" menu, direct scan to hard disk, Mark bad cluster, select "Advanced" → "Wicked sector retset" under "Operations" menu, Finally, the bad cluster into a separate partition, and then through the "Hide Partiton" command to hide the partition, this is done.

If the computer starts to appear the information "TRACK 0 bad,disk unusable", then fixes up is more troublesome, because this information explains the hard disk 0 track damage, generally appears this kind of situation, most people put the hard disk as the scrap processing. But is not absolutely cannot repair, the principle is very simple, as long as uses 1 sectors to replace 0 sectors to be OK, below lets us try!

This time please "Diskman" to help us, it is a more commonly used hard disk tools, in the Pure DOS run, in the "Hard drive" menu to modify the disk (generally for C), and then enter the "tool" → "parameter modification" → "Start cylinder" value from "0" to "1", determined to save exit. You can repartition the hard disk.

If none of the above methods worked, then the ultimate Dafa-low-level format would have to be used. This is the most not recommended by the author of a method, because the lower grid will be divided into track and sector, the standard address information, the setting of cross factors, such as information, will cause severe wear on the hard disk, the existing physical bad track hard disk is even worse, and the low grid will all the data empty, is an irreversible process. Therefore, do not lower the grid unless you have to. Commonly used low grid tools have DM million version, Lformat, etc., can be downloaded in the Chinese military software Park. Remember that the lower-lattice hard disk must be formatted with the advanced format before it can be used.
