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 Protection—the methods to Fix Hard Disk Errors
Dec 2nd
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.
