Thanks for your kind replies, Northwind!
It's just a piece of metal used to attach the disk into the notebook. It's not part of the HDD. I probably shouldn't have mentioned it, it's rather confusing. The question should be rather this: can I power up a 2.5" HDD if the PCB of the HDD faces upwards? I think it is silly to even ask this and the answer is very likely to be 'yes' but looking at the drive it just feels weird. I have never plugged in a drive that would be positioned like this so I am not comfortable with it and would be very glad for confirmation that it is ok to do so

Many thanks in advance!!

You're welcome.
Now i understand, you're probably referring to the disk tray, that metal that holds drive in it's place inside the notebook hard drive bay. OK, you can remove that, but as i said and freakzy also advised, you won't be able to see if the spindle rotates or not.

If you can still bear with me ...

Is there any other way to check the spindle moving other than listening to the sound?
Not without expensive equipment or without opening the tray, and i really don't understand why is it giving you such a hard time.
Just power up the drive, put your ear onto the drive and listen. If it spins up, you will hear platters rotating and heads moving. If not, you will hear absolutely nothing, or some silent hummmmm with disk trying to spin up but fail. [/quote]

The hissing sound that I hear - could it be something other than the spindle rotating? I have never really heard a dead drive plugged in.
Yes, could be stiction. This is the case where heads are stuck to the platters and platters can't rotate.

If there is no other way to check the spindle, basically the only thing I can do is to unscrew the PCB and check it for heat-related damage, right? If I am careful that shouldn't be too risky, should it? Just unscrew, take out, check out and possibly put back.
You can do this, but i doubt you will see anything helpful.
