Definitely check for stiction, it's a very common problem on RD53s. If
the data on them is worth saving, you can probably make a clean enough
environment in your home or office to open up the drive assembly and
nudge the head loose from the sticky rubber that it's parked against.
You can probably get at least one good read out of it without it
crashing (I know folks who've opened up their RD53s, reassembled them,
and run them successfully for months afterward. YMMV!)
