I'll try this, but it might take me a while before I report back: I get
this problem only once every two weeks or so (It's hotplugged daily)

I'm assuming you mean leave the power plugged in, but yank and replug
the SATA cable? Might be a bit tricky considering I'd need to open it up
(the tray combines power and SATA), and it's in a remote location.
Thank you for your suggestions, I'll report back on the next failure.
