Seagate st3750330as 750gb not working after flash

[funkyblue]

Hello,

I have a ST3750220AU Seagate 750gb Drive.
It had firmware: SD81 on it.
It was making clicking noises, so I did a full test with Seatools. It found no errors.
Many forums suggested updating the firmware.
i Found the latest version SD14 on the internet and flashed the drive. Flashing seemed to have gone fine and I reset computer when I saw "Cycle power
to continue..."

Now I only get drive error when booting. Vista does not see the drive at all. Seatools, finds the drive, but every test fails.

If there anyway I can repair the firmware or restore it back to the original firmware?

Seagate is refusing to help, as the drive is an OEM version, from an External Maxtor Basics unit. (I decided to make it an internal drive three months ago, and it has been working fine.)

I cannot return the drive, so am thinking I am out of luck.

Thanks in advance.

your drive is gone baby gone, buy a new one.

So no chance of repairing the firmware? Is there a way I can extract the firmware SD81 from an identical drive and reflash?

Thanks

It's not a cell phone. Blame internet for the idea of fw update. The fw is not only in a rom but also recorded. Only a pro - and at high cost - can maybe fix it again with special equipment. Ask seagate for their recovery fees if you need the data... Good luck.

Ok thanks. It's just weird the FW update did not work, when it seem to. I have a backup of all the data. Just annoying I cannot RMA!
Thanks
