You can get most desktop drives to reinitialize themselves with a mild
tap.
I don't suggest trying that on a drive you depend upon. And while it
generally does no harm to move a running hard drive, you should be careful
not to drop, jar, shake or abuse it while it is running. If any one of
those
things were to happen while the drive was running, a head crash or other
drive failure is possible.

One notorious 10 Mb hard drive Radio Shack sold would only start after a
weekend if you first dropped it about a foot onto a desk!
