Methods to fix hdd bad sectors

April - 28 - 2011

When the HDD of your computer has an increased number of bad sectors this could be a sign to replace it. There are physical bad sectors and logical bad sectors. If you want to fix the logical bad sectors it could be a hope but for fixing the physical bad sectors there are no chances. An advice for this problem would be to use the “kill disk” software. This software will isolate the bad sectors and rearrange the files and folders which are not affected. You will lose the space the bad sectors used to fill (for example if the bad sectors occupied 3 GB, your HDD will lose 3 GB of its memory).

You have to know that when using this software to fix the bad sectors on your HDD you will have to format the disk and thus you will lose any data on it. Taking into consideration this, you should save any data you’ll need later and after that you will try to backup the critical files on the HDD (this could be links, documents, pictures or anything you’ve downloaded from the internet). The next step would be to repair bad sectors by running Check Desk). Go to My Computer, click on your HDD (C Drive), choose Properties and select the “Error Checking” (from Tools). Here you’ll find an option for scanning and attempting to recover the bad sectors. This action will take a while to complete. If the checking reports a lot of bad sectors, you could find in you computer (at Disk Drives in the Device Manager of your HDD the producer’s site). Download from this site a drive integrity tool for making a test of the HDD.

If there are reported a lot of errors on the drive you should ask the producer to replace your HDD. You should be very careful when noticing a bad sector because even if you manage to isolate it afterwards it could spread in many other sectors across the HDD.
