I appreciate if you can please answer. I have a Western digital 500gb internal harddrive, which stopped working and not booting. its giving a siren sound (4 times near start) and then computer display updates as not bootable.
Model number: WD5000AAKS
Sound as .wav file: http://www.4shared.com/audio/G0xM0qrf/ext_-1.html
This is the drive I have: http://www.newegg.com/Product/Product.a … 6822136073
the link has images of the drive.
From the siren sound, after researching it appeared like spindle stopped for some reason,…not sure if it is due to firmware or pcb part. The drive was working perfectly in desktop and nothing changed. It just died after a shutdown and then restart. I do not poweroff my computer and do a shutdown once every 2 months or so.
My question is ,… for WD50000AAKS does the head alignment change after opening the lid? Does the head alignment depend on the screw of the lid?
Appreciate any input on siren sound and if the lid opening changes head alignment.
