Protect Your Computer—Facts about Hard Disk Problems
Dec 3rd
Although low hard disk quality can lead to bad tracks, you should be aware that the most problems are produced by being used improperly. So in order to protect your hard disk as well as computer, I would like to tell you the facts about hard disk problems and bad tracks in particular.
It can categorize into two kinds: logical and physical bad tracks. Put in simple way, logical one is produced by using certain software or disk improperly while physical bad track is due to problem of magnetic media of hard disk itself. As a matter of fact, to fix the former is much easier to fix than the latter one.
If you find your hard disk is troubled with following problems, it is necessity for you to check whether there is bad track in the disks.
As a matter of fact, your system is not affected by any virus but cannot startup normally and come up with some prompts like “Sector not found” or “General error in reading drive C”. Every time you start up system, it will run Scan disk program to scan disk errors. The normal running sound has changed into weird creaking. Or when formatting hard disk, it stops at certain schedule and then report errors that it cannot finish the whole task. If you perform “FDISK” to hard disk, it repeats at certain schedule. What is worse, the computer might fall into blue screen without any wrong operation.
How to fix bad tracks?
As it is extremely rigorous requirement for interior working environment in the hard disk, any tiny dust can result in irreversible damages. Therefore, if there is any bad track in the disk, you cannot fix the problems by taking apart the disks but can turn to other specific tools to help you so as to minimize the loss. After confirming the bad tracks in the disks, you are not still sure whether they belong to logical or physical. So, you have to fix disk errors from simple to complex means. The common logical problems can be solved by using Windows program or others. But as for physical ones, you need further repair to guarantee the safety of hard disk data and normal usage.
Shield physical bad tracks
If bad track still exits after low-level formatting, it is no doubt that there are physical bad tracks on it. Such problem is produced usually by furious impinge or abrupt power-off during using hard disk and disk head may likely collide with disk when it is tail-wagging. Even though you use disk checking program to mark those bad tracks so as to forbid operating system visiting this sector, the physical ones can extend after a period of time. That is to say, although you have marked bad ones, hard disk is likely to visit the sectors closed to bad tracks which can deteriorate the situation. In order to avoid such problem, you had better shield bad tracks into an unused partition.
By doing the above steps, you can fix logical bad tracks or shield bad tracks into hidden partition so as to ensure the stability of system running and safety of data files. In this way, you can refresh hard disks.
Hard Disk—Useful Methods to Fix Hard Disk Problems
Nov 27th
It is known to all that hard disk is storage of the computer. If there is any problem in it, it can not only harm hard disk but also slow down your computer. Therefore, you should need to know how to protect hard disk, even fix the problems. This is what I want to tell you in this article.
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.
