Hard Disk Maintenance—How to Fix Disk Errors
Dec 2nd
When talking about computer maintenance, it is probably to neglect hard disk. As a matter of fact, the disks are quite fragile. Any dust or improper temperature can cause unexpected damage to them. But, in this article, you can learn some disk errors brought by operation mistakes or system problem.
Hard disk works normally and running speed is improved greatly after being scanned thoroughly. But such situation can not last for a long time since the disks are troubled with errors again. Besides scanning disk, what can you do to solve this problem? There is not any bad track in the hard disks, why it always pops up disk errors?
Do not worry. In this article, I would like to tell you how to fix disk errors correctly–the common disk errors and solutions.
First, computer reminds you that “c：drive failure run setup utility，press F1 to resume”.
Such problem is caused by incorrect disk parameter settings. So you can use floppy disk to lead into hard disk and reset disk parameter to get rid of this error.
Second, computer is display “no rom basic，system halted”.
The problem should be blamed for broken leading programs or system affected by viruses. Or some marks in the partitions have been juggled. In order to handle this disk error, you can start up floppy disk and perform the order of “f disk/mbr”. And everything will go back to normal track again. The working theory is that “f disk” contains the main code of leading program. By using such order, the correct program and code can cover those in the hard disk. This is the quick and clever step to fix this problem.
Third, it reminds that “error loading operating system” or “missing operating system”.
It should be blamed for dos boot record error. The record is situated in the logical 0 sector and produced by high-level formatting order of “format”. After checking partition table correctly, the program reads dos boot record according to the original address of dos partition. If it fails to do that five times continuously, the system reminds you that “error loading operating system”.
And if it succeeds, the booting program will send the record to 0:7c00h of memory and check the last two bytes of boot record are 55aah or not. If not, you can see the prompt of “missing operation system”.
Well, under such circumstance, you have to turn to certain specific software to help you fix the errors. Or, you can try to format disks but have to shoulder the risk of losing data.
Fourth, it displays “invalid drive specification”.
You can format partitions again. If there is any malfunction in the disk partition, formatting disk is the basic measure to solve such problem. But at the same time, all the information in the partition is deleted completely without question. In order to fix disk errors and protect your computer as well, you should follow the principle that high-level formatting should be the priority, then partition formatting and low-level formatting comes last.
To be frankly, the number of hard disk errors is far from the ones mentioned above. If you really want to protect hard disk, you cannot be too careful to use computer correctly.
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.
