It's bad enough my (main) hard drive has suddenly decided to go crazy--for weeks now, it is going almost incessantly, stopping for only a few seconds every ten munites or so--but it actually is buzzing like mad. I feel like I've got a bee in the room with me. I'm afraid the damned thing is going to explode, any minute.
You can take it it is not a fan problem. I've checked.
Both my drives are fairly new. What could be the problem here, and how can I begin addressing it?
Then the simple things. Uncover the innards and apply a finger to the case of each HD in turn. It is possible that there is a stray screw rattling about or a loose bit of something which sets up a resonant chatter.
