Hard disk bad tracks, especially physical ones must be the most headachy problems in the disk errors. Such problem can cause your computer from frequent blue screen to data loss. In order to fix disk error, I will tell you some methods including using Windows scanning tool, low-level formatting and hiding those errors.

In the first place, you can restore logical bad tracks by using Windows disk scanning tool.
Right-click the drive letter you want to scan, click orderly in the windows “Properties”—“Tools”—“Check Now” and set the type as scanning thoroughly and restore errors automatically. Then click “Start”. How long it will take to scan the disk is mainly dependent on disk capacity and scanning options.

If the logical bad tracks in the system section lead to the incapable computer startup, you can use the startup disk of Windows98/Me. Following DOS prompts, you can type “Scandisk *(the drive letter)” and press “Enter”. Once finding bad track, the program will remind you whether you want to fix it and then start to repair since you choose “Yes”. In this way, you can solve many problems caused by logical bad tracks in the system section which may result in the computer is unable to start up normally.

However, since the methods mentioned above is mainly relied on repairing logical bad tracks by itself and cannot repair those physical ones. In this regard, if you encounter physical bad tracks, what will you do?

You can use Scandisk order to check physical bad tracks.
It can mark the bad ones in order that computer does not perform read-write operations to this region any more. However, since physical ones have “infectivity” that can extend widely, all the data restored close-by this region is in danger as well.

Scandisk stops every time when it has found a problem. At that moment, you should take stock of the value when it stops. For example, supposed the value is 22% and the total number of disk capacity is 2GB, then 2GB×22%=0.44GB. This result means that bad tracks in the hard disk may start from 440MB. Considering its extension, you should set enough buffers.

Or, you can use software to hide those physical problems. Some can reset, alter dynamically, hide or display disk partition under the situation that they do not destroy any data. And as for fixing hard disk 0 sector damage problems, you also can turn to certain tools, because it is too professional for you to repair it.

Use low-level formatting to fix errors.
Finally, you can consider using this method to handle this problem if all of the mentioned ones can not work and you do not reconcile to desert the hard disk. However, low-level formatting will rearrange tracks and sectors, label address information and set cross gene, so it may take a long time to read and write the disks. The more you use it, the more damages have been done to hard disk. What is worse, such formatting can destroy all the data downrightly and it is irreversible. Therefore, you should perform high-level formatting operation ahead of doing that.
