Is the activity light on the hard drive blinking? Is the drive spinning up at all?

A lot of SE's shipped with 20mb stepper motor Miniscribe drives. Stiction can cause the drive to not spin up but you can free the head if you *VERY CAREFULLY* turn the stepper arm a *VERY TINY AMOUNT*.

If it spins up it will either instantly crash or it will go ready but I don't promise any reliability unless you do a surface check with one of the many disk utilities out there.
