Unfamiliar hard drive failure sound

[BlvckFox]

Hello all, Just registered!

Ive been toying around with hard drives lately, mainly tinkering with drives I dont need.
I found a 1tb portable Western Digital Hard drive.(WD10TMVW) It is making quite a peculiar beeping sound.
Ive uploaded the sound it makes...

I opened it up and set the head back to its parking position, as it was on the platter.
The same peculiar noise persists.

Any ideas what the noise could be trying to tell me?
Any help would be valued!

Thanks.

The noise you recorded is caused by stiction (heads stuck to platters).
If you say you parked heads back to ramp and same behavior insists, then heads were stuck to platters again (for some reason), or you didn't unstuck heads properly. There is a small chance that motor is the culprit, but it is 0,1% for this drive.

I'm sure I parked the heads. Perhaps they aren't parked precisely?
I've opened it up again and the heads are parked. Will an uploaded image help?

I think iit sounds like stiction too.

Send pic, but remember is you open the drive without clean beanch you put in risk data.

Did you park the heads off the platters and on the load/unload ramp? Can you rotate the motor afterwards by hand?
