I am a freelance computer repairman, and quite often I have customers come in with hard drives that have corrupted clusters. (Right now I have 3 computers with this issue). In the past I have been replacing the hard disks for fear of my customers coming back a month or so later with hard disk failure again.
My question is: Is it Okay to repair the hard drives, or would it be better to replace the hard disks? Someone has told me that once you start to have corrupted clusters means that the hard disk is starting to fail and more and more clusters will go bad, so even though you fix the bad ones. later you will have problems due to more bad clusters.
I am needing some good advise. I hate to make my customers spend extra money if they don't need to, but I don't want them having trouble right away again, too.
