"Another one bit the dust", by Queen... time to check if a fall from any
height on a concrete surface would have exploded the drive. We want photo.

"It's a hard life" : after having been the cherished drive on which
everyone relied, it is now persecuted.

"Hammer to fall": at least, do you have some hammer ?

If all else fail, you might get some expanding-foam (in can, urethane)
injected inside the drive: this would preclude any easy restoration.
