This hard drive was originally in a seagate freeagent external enclosure.
One morning when i went to turn it on - it would spin up, turn off (spin down) and then try spinning back up (in a continuous loop). The hard drive does not click at all - but is not recognized in windows or the bios.
I searched the web and found out that this is caused by a firmware bug/issue - and ive downloaded the new firmware - but I cant flash it as it is not detected by my computer.
So I looked on the web and found this guide on youtube http://www.youtube.com/watch?v=29FztWJVxbM
And tried doing the same thing for my hard drive.
When I connect it to my pc (in hyperterminal with apiece of card under the pcb) and try to do any commands such as
I get the following error that keeps repeating:
And when I remove the card from under the pcb If just gets stuck in a loop again (spin up,down etc)
(P) SATA Reset
Does anyone know how to fix this? - or what im doing thats wrong?
Thanks in advance for any help,
I have over 900gb of data on the drive I want to get back

Hi thanks for the reply
Im using a usb to serial ttl lead and connecting it to the pins on the back of the hard drive (where the jumpers go).
The piece of paper/card is under the pcb preventing contact as in the youtube vid i posted earlier.
The pins are round the right way (ive tried the send/recieve the other way round - but all i get is a blank screen in hyperterminal - cant send any commands).
Im not sure what else to try?

Hi thanks again for the reply,
ive now tried blanking the middle one (that goes to the motor) and both with no luck. I tried sending the commands and just get this error back that repeats:
I will now try putty
Any other ideas?

Hello thanks for the reply -
I just tried it again (being case sensitive),
And it got it to do the first command
Spin Down Complete
Elapsed Time 0.132 msecs
But trying to do the S.M.A.R.T. erase (create S.M.A.R.T. sector) or any other commands:
F3 1>N1 (enter)
I take it you cant do it with the card/paper under the pcb blocking the head contacts - but as soon as I remove the piece of card it gets stuck in a continuous loop powering on and off, preventing me from entering any commands:
(P) SATA Reset
Any ideas how to get round this?
Thanks again for the help

I just managed to do it
Whilst it got stuck in the loop of powering up/down I managed to send a command quickly and do the smart erase and it seems to be working correctly now - I I just have to flash the firmware now.
Can this be done over a usb to sata bridge?
Thanks again for your help
