The directory or file C: is corrupt or unreadable Please run chdsk utility

[BC_Programmer]

When chkdsk /r completes it always reports have found and repaired one or more errors. If you didn't see that message I suggest you may not have run chkdsk /r

chkdsk does not always state that it "found and repaired one or more errors" one particular case in which it might neglect to do so is if there were no errors to report, at which point it simply states that "chkdsk has checked the drive and found no errors" or a message to that effect.

I do not insist. If you're certain you did follow that procedure that's fine. I just want to make sure it's been done. Thank you.

There were errors, for sure, I saw them, but it was hard to read since the computer reboots.  What other software can I use?

[Allan]

Whoa - time warp. You're responding to a post in your thread from a year ago?

Sure I am; let me say this, I still haven't replaced the drive. 
 Interestingly, Seatools for DOS claims, the drive is fine, I did a long and short SMART test.

The drive doesn't want to quit but those error messages don't quit either.

So theres only one thing I can try, and thats reformatting and starting fresh, perhaps it'll work otherwise I'll have to give in and finally replace it.
