Seems to be fps (might have been a freak correlation but cleaning my base up and removing excess light sources helped cull the issue down) tied and easily triggered on reloads and by leaving a bunch of drives cluttered near the slots in general.
If you loaded the game with the drive in, you have to restart it again to reset the slot.
It can also randomly trigger when removing/plugging in drives, but you can correct it by plugging the bugged drive back in UNLESS YOU STORE IT- I keep a dummy drive on my desk to test slots before loading my drive box up to send off as prevention, as if you load the bugged drive into the box, you cannot fix it without reloading the game, even if you take all the drives back out of the box and try to plug them back into the offending slot.
