fzabkar, I just found out what actually happend to my laptop. It was dropped, after that Windows would run very slowly, would take 5 minutes or so just to open a window... a few days later the hard drive is making the stuck spindle sound and is no longer detected in the BIOS settings. Could this be fluid problems in the bearings or a stiction? I'm guessing fluid problems don't result from a knock but a stiction would likely be caused from that?
Is there a post explaining what a stiction looks like and how to fix it? I will be able to see immediately if it's that if I know what a stiction looks like, haha. Thankss xxx
Edit: CK, I do know what to wear.. I think. I have anti-static finger cots but I still wouldn't touch the platter freely etc. Anyway I'm interested in this stiction problem, it may be exactly that. Any idea how I would tell if it's a stiction? x
I'm not a data recovery professional, so I can't talk from experience (the last time I worked on the mechanicals of a hard drive was 20 years ago). However, since you have access to a cleanroom, you should be able to see whether the heads are on the platter or on the loading ramp. If they're on the platter, then that's a stiction fault. Otherwise, if they're on the ramp, then the motor is probably seized, in which case you won't be able to turn it by hand.
Here is a post that you may want to read:

That is, Windows may have been having difficulty reading bad sectors. If you were perhaps thinking that Windows was running slowly because the motor was spinning slowly, then that's not possible. The motor either spins up to speed or it doesn't.
