I should mention that an external case-free USB adapter is the best way
to attempt recovery of failed drives.  You can even run the IDE/SATA/Power
cable to a box in the freezer (and the USB adapter can sit on top of the
freezer and a long USB cable go to your computer) - which often helps recover
data from failing drives.
