About two weeks ago I had my D drive just not respond anymore..  It showed in the BIOS but not in the window's browser.. also some sectors in the physical drive seem to not work properly showing errors...  Dell sent me a brand new drive...  The tech guy was real nice and attentative..
OH NO! The "new" one did not "respond" either...    It shows up in the BIOS but not in the windows browser..  Dell said it might be a windows problem as well...   I could not stay with the tech guy too long but will be calling them back..     no conclusions yet...

The tech said it could have been (maybe) something I downloded...  worm?

I bring this to your attention in case someone might be having the same symtom problems with their hard drive...
