Mark: Scott has the right plan for you. Buy a new drive and install
it, when you take out the defective one.
Send the defective drive in on an RMA and they will probably replace
it with a remanufactured drive and you keep
that one available as a spare or install it in another box.. If your
box is like 3 of ours, it is a PITA to R&R a 5.25" drive. We have 2
Dell Dimensions that are very easy to open (that's the idea, if it
works). Dell Latin America replaced one of them, after I got it,
because I could not open it. It took two (2) of their Tech Support
people, to get the thing open, so I asked for a new one. Plastic
cases...... Lanny
