I have a laptop that has been blue screening. I did a chkdsk /r and then a chkdsk /r. There are quite a few problems being reported in chkdsk, and it appears to fix the issues that it finds. There were errors like "Windows replaced bad clusters in file 43732" and "File Record Segment XXXX is unreadable". The computer seems to be running fine now...but I need to give it back to the end user and let them use it for awhile to see if the blue screening continues. In this case, is there a high likely hood that the physical hard disk is damaged, or is it more likely that there was just corruption on the disk, in which case hopefully chkdsk fixed everything? I know that question is difficult to answer due to the limited amount of information, but I just need to know if I should advise the end user to replace the hard drive or not.
