Hi folks edit Sorry about the topic. Apparently when posting the limit of it is never displayed and you can't edit it once posted. =( Topic was supposed to be: Seagate ST3500320AS SD15 500GB. Suspected BSY but does not spin up when PCB is reseated. I have fixed a few of these BSY disks now but stumbled across one yesterday that behaved differently. When I put the PCB back it sounds like it tries to spin up but fails and then repeatedly tries again. So it's like a 'bzzzzz', 'silence', 'bzzzzz', 'silence', 'bzzzzz', 'silence', 'bzzzzz', 'silence', 'bzzzzz', 'silence', 'bzzzzz' and so on. Have anyone stumbled across something similar and if so, is there a fix? The sound is not a 'click' but more a 'bzzzz' or 'buzzing'. All the symptoms indicated that it was a BSY error and I can log into the disk and spin it down but when i try to spin it up the terminal just get's stuck and the drive makes the said noises and I never get a reply from the terminal.
