Well, kinda.

Have two computers - my main one which has a failing internal drive (doesn’t contain crucial stuff) and an old Linux machine which…has a failing internal drive.

Took them both out of their corners and blew the dust out - so much dust! Reseated the cables, moved some things around, and plugged 'em back in.

The main computer has the same problem as before, so I’m recovering as much data as I can before swapping out the dead drive.

The Linux computer won’t even power on now. Gonna have to look at that this weekend.

EDIT: The Linux machine is back. Turns out the power plug I used for the internal drive is…questionable. Grabbed a different one and it came up fine. Well, fine to the point of recovery at least.
