Sometimes, logical bad track can result from using formal vision of software. Is it weird? Actually, when some software reads data into certain sectors, others are excluded to visit these sectors. In such condition, the scanning program may consider mistakenly there are bad tracks in the sectors and you do not need to fix those tracks at all. But, do not worry about that, such software uses those ways decreasingly.

Normally, logical bad track is caused by improper using hard disk. For example, if the computer has to restart unexpectedly when hard disk is reading data, logical bad tracks are created probably at this moment. What is worse, it may even lead to physical bad tracks. In fact, you can use Windows disk tools to scan the whole disk and to fix errors automatically. The specific procedure is as follows:
In “My Computer”, you can right-click the drive letter, click “Properties”—“Tools”—“Check Now” and tick “Automatically fix file system errors” and “Scan for and attempt recovery of bad sectors”. At last, click “Start” and then everything is OK.

The scanning time is dependent on disk capability and scanning options. But you should be clear about that all the operating systems except Windows 98 do not display details of every sector. Therefore, it is wise for you to choose disk detecting tool of DOS—Scandisk. Such program can check every sector and mark the bad track to prevent operating system to visit this region any more. By doing this, it can guarantee to run system stably and restore data safely.

If you follow the steps mentioned above, the restored bad tracks still exit in the hard disk but just have been marked, so the system will not continue to visit it. However, since you keep on using hard disk, it is likely such bad tracks can expand. In this regard, to scan and mark the bad tracks can not eradicate this trouble. So, it is appropriate for you to back up disk data and rearrange partitions to format disk. commonly, if the problem of hard disk is just involved in logical bad track, to back up data is qualified enough to handle this problem completely. Of course, it is best that you apply Scandisk to detect hard disk again in DOS environment to make sure logical bad tracks are restored thoroughly after rearranging partitions and formatting disk.

In conclusion, to be honestly, the problem of hard disk is rather professional. You can have a try to fix them or let hard disk programs help you.
