Stuck disks may get free if the drive is twisted with rapid acceleration
aroud the spindle axis. If this doesn't help, you can try to slap the edge
of the drive against something rigid, in a direction you suspect the heads
to go outward.

Uhh, don't try this at home with a drive you want to carry on using. What
you call dust-free is orders of magnitude away from a real cleanroom, and
the omnipresent dust through the hairdryer must feel like a hailstorm to the
poor disk.

I'm glad you recovered your data, this is what the exercise is good for, but
don't expect reliability or lifetime from that disk.

The headcrash has certainly damaged the surface, with micro-debries now
flying around, causing more damage over time. There is a filter in
rotational direction, meant to capture the worst.
