I notice that "Spinrite"was mentioned a couple of times.
When Steve Gibson wrote that program, many years ago now, HD's were still in their infancy.
Way back then, I put out the $99 to buy the program. But I must confess that I've not used it now in many years. If I have any reason to suspect that a HD may be failing, I just replace it ASAP!
Failing or questionable Hard Drives are just NOT worth fussing around with.
When I set up a new OS on an old drive, I just instruct the Setup program to delete all the previous partitions. Then I let the new OS (Install Program) do it's own partitioning and formatting. Anything that was previously on the HD is well erased.
If a 100% clean HD is required, then just buy a NEW one, instead of re-using an old one.
Once in a while, when I get a used HD with a questionable history, I run a Low Level Format program on it, and that puts it back to Factory New! And like at the factory, the LL Format blocks out any failing or questionable sectors, so they will never be used. *
Every HD has its own Bad Sector Map, even though most folks don't know about it.

* On the large HD's today, a LL Format can take many hours (or days).
Cheers mate!
