Conclusion On Bad sectors - If your flash drive has been started to show errors and bad sectors, you no longer should utilise that flash drive as a hard disk while taking safer side you need to replace it.
I have a flash drive which is showing some irregularities from last few days. I guess the problem is regarding the bad sectors on flash drive. I think so because I noticed some of the files are corrupted in the flash drive as I copied the files again from backup it become corrupted again. My friends are suggesting to replace this flash drive with the newer one but I am interested if the drive can be still utilised by marking up the bad sectors of the drive. How can I fix the bad sectors of my flash drive? Can I still use it even after having bad sectors in it?
You need to make it clear in your mind that a flash drive has not naturally tend to have bad sectors or errors. You don’t need to check for the errors in it if it is behaving in wrong way. Actually a flash drive itself possess a built in error correction and detection program. It does mean that if any error occurs in your flash drive it is capable to be recovered itself but if it is showing you some error means the condition of your flash drive is comparatively worse than expected.
Flash drive has a totally different rule for working unlikely to the hard disk. Any tool to recover the tool like CHKDSK, Scandisk etc. shows failure in the case when flash drive is undergoing ‘surface errors.’
In case the flash drive shows bad sectors it creates a terrible condition for you regarding data loss and serious failure of operations. Actually flash drive does not show stability for location of bad sectors, the site where you are able to see any bad sector today might be seen anywhere else tomorrow or later. Thus it really worth to change this kind of drive and buy a new one.
Still it all depends on the design of the flash drive and upto some extent the capability of flash drive depends on the manufacturer of the flash drive.
I suggest to buy a new drive instead of using the same containing errors like bad sectors. I believe that it does depends on the drive’s dsign that how efficiently it can be recovered itself and what is it’s deadline of recovery but I can’t take a risk of utilising the bad sector containing flash drive ever under the threat of data loss.
