Hello. I have a laptop with hard disk having 32 bad sectors. I used DRevitalize to scan the drive for bad sectors and fix them (alternative for HDD Regenerator). It successfully fixed all those sectors but my SMART still says "Reallocated bad sectors" - Fail.. I rescanned disk after 3 days and it doesn't have any more bad sectors. What to do?? It's irritating because my laptop will always warn me about it every time I turn it on..

What you do is ensure you have backups and think about getting a new hard disk. Once SMART starts telling you you have bad sectors things can only get worse. There is no wqay to reset the warning.

A new hard disk has an area set aside to relocate bad sectors. This is done invisibly to the user. Once this space is full, any more bad sectors and the data on them is lost. What SMART is telling you is that this space is full and it cannot relocate any more bad sectors.

A new hard disk is the only way to resolve the problem with any degree of certainty. At best these disk regenerators and revitalisers are just a temporary fix.

I have hears that the SMART values can be reset but only with the advanced (and expensive) tools available to a data recovery professional.

A disk regenerator causes the disk to internally remap the bad sectors and that solves the immediate problem. But when a drive develops a large number of bad sectors there is usually some underlying cause and no software tool can repair that. Whatever that something is (usually unknown and uncorrectable) will in time create more bad sectors. Until one day there are thousands of them and the computer has obvious issues. That can happen in a very short period of time.

SMART has given you a valuable warning. Many people are not so lucky as many drives fail with no warning at all. I have experienced this. Don't risk your data to a drive of very questionable health. Backup your data now as tomorrow may be too late.
