If the drive was dropped whilst it was spinning, then it may have
suffered a head crash, which means that there will most likely be
media damage, or head damage, or both. Very often the spindle motor
bearing is seized. Replacing the motor is a major job. :-(

Here are some sound samples from failed drives:

There is a slim chance that the failure to spin up is due to stiction,
if the heads have come to rest on a smooth section of the platters
rather than their normal landing area.
