Hard drive Bad track repair simple two method

Hard drive working sounds weird

When we were on duty, a netizen asked us when you open, run, or copy a file or program, your computer becomes slower than it used to be, and reads the disk over and over for a long time, then makes an error, or Windows prompts "unreadable or unable to write to the file," and a blue screen occurs when you have a serious problem. When you open the chassis, you can hear the hard drive read and write sound from the original "Cha Cha" friction into an abnormal sound.

Use the system under the hard disk scan when the red "B" mark, format the hard drive, to a certain progress stalled, the last error exit. On the hard disk with "Fdisk" command to partition, to a certain progress will be repeated into retreat, can not be completed, ask a friend to know that may be hard drive appeared bad, but do not know can be repaired.

In view of the above situation, small series think, first of all, this netizen should first confirm hard drive bad way is logical bad way or physical bad way, the method is very simple, use boot disk boot to DOS, execute "ScanDisk x:" (X for the letter), ScanDisk program will check hard disk, The resulting logical bad way will pop up a dialog box and choose Fix it to perform a primary fix on the logical bad path. If the scanner is stalled at a certain pace, then the hard drive has a physical bad way.

Logical bad way, small problem

For the physical bad way, we should adopt the method of isolation, to minimize the loss, to prevent the further spread of bad road, for the logical bad way, we can try to repair, see if we can solve the problem, the logical bad way of repair relatively simple, we can do it ourselves.

After normal startup, go back to windows and go to "My Computer" and choose a hard drive with logical bad path. Right-click, select "Properties" → "tools" → "Start checking" pop-up "ScanDisk", select "Full" and "Automatic Fix Error" Tick, click "Start", The partition is scanned and repaired.

If the system does not scan at startup or is unable to enter the Windows system, we can also use the floppy disk or CD-ROM boot disk to start the computer, under the appropriate letter, such as "A:" Under the Run ScanDisk *: (Note: * For the hard drive to scan the letter), Carriage return later on the corresponding need to scan the repair of hard disk partitions to repair, for the general logic bad way, the above methods are basically can be repaired.

Loss of space, stability

If it is a physical bad way may be a bit of trouble, but if the hard drive is still in the warranty, I can go directly to find the seller to solve, if there is no warranty, then we need to do their own, the most common to the number of partition magician software repair. By repartition the hard disk, hide the hard disk space with the physical bad path, and isolate it.

Specific practice: Start PM, check the "check" command under the "Operations" menu, direct scan the hard disk, mark the bad cluster, select the "Operations" menu "Advanced" → "Bad sector retset", Finally, divide the bad cluster into a separate partition, and then hide the partition by using the "Hide Partiton" command.

Another way is to use the Fdisk and Formatting command format, first, if possible, you can first test the useful information, and then the hard disk with Fdisk into a disk, and then formatted with format, when encountered can not repair the bad block face format always try to repair, The percentage that is recorded below. Then press Ctrl+break to force the task to terminate, using the total disk capacity x percentage, to derive this portion of the normal disk capacity.
