I have to add to this: with storage as cheap as it is these days,
depending on the server, a single sign of badness often is enough
for me to just replace the disk. I might then run the old disk
through a testing machine and use it in less critical machines if it
seems fine, but in general, my motto is: suspicious stuff? replace
the drive.
