OTOH that the drive was opened one time, does not make it
insignificantly risky to open it a second time.

Opening the hard disk much likely was a big mistake. [1]
I only would risk it a second time, if anything else doesn't help.

2 Cents,

I had success with brute force.

Opening the hard disk much likely was a big mistake.

However, if my drives fail with this click-click noise and something
should be missing by the backups, I demount the drives, but let them
connected to the PSU and mobo, then I hit the drives from all
directions with increasing force, from soft with the hand to not that
soft with a stick, not necessarily while lying flat on a
table.
