Careful what you use on that one!
I'd give good odds that the drive itself is ok, the controller's
cmos registers have been altered so it thinks it's got a different
number of heads. Check this BEFORE you run any kind of recovery
programme on the drive!
You'll need to have the drive type number or it's specs handy
to re-set them.

Hope you saw this in time!
