External harddrive overvoltage Seagate Barracuda 7200.10

[Zephyrlius]

Help!

Did connect my computer charger to the external harddrive.

Now it wont work at all, the computer cant sense the usb and the led is just flashing.

Have opened the external case and removed the harddrive.

Do i need to send it somewhere to recover the data or is there an easy fix?

Did add some pics, marked with red where it smells burned but dont know if it should or not.

It doesnt spin at all, I cant hear it...

Check the two large black TVS diodes, bottom right in your first pic.

Search this forum for more details.

Almost certainly the issue, fixable DIY. Good luck!

Sir ,
you did not respond to seans comment .Would you be interested in a do it yourself solution or like it to be outsourced ?

I would try to connect the drive to the PC directly by SATA (without USB box) and check if the drive spins. If it doesn't spin chck if the power supply from the computer shuts down. If so then it's a TVS issue, you can even start by measuring the TVS diodes to avoid damage to the computer/psu/other drives.

If the drive still doesn't spin when you swap/remove the damaged diodes or if the computer powers up with the drive connected to it and the problem is not the TVS you can try to find on ebay another PCB/drive exactly from the same model as your drive and with THE SAME FIRMWARE VERSION. Of 7200.10 as long as you match the Firmware version and the model a direct PCB swap will work, as long as the pre-amp is not damaged as well.

DO NOT OPEN THE DRIVE.

Regards.

Spildit ,
If he buys a new donor pcb he does not need rom transfer to it ? . Also i never suggest anyone to just yank the hdd to pc powersupply without checking the TVS diodes .

I felt the eadiest way for me was to buy a new PCB. Will uppdate you when it has arrived. Thank you all for the help.

I will try to restore the drive when my data is hopefully restored. I decided my data on the drive to be too much valuable for me to try myself without it being backuped.

Seagate 7200.10 - prior to F3 arch.

F3 ARCH have adaptives on ROM. You loose ROM you are in trouble.

7200.10 have only ROM code. As long as you match ROM code you don't have to swap ROM chip. Version of firmware have to be the same on the donor drive. This will work on all Seagate prior to F3 arch.

My Bad ,
Did not see it was not F3 .Sure Older Segates Were a joy to play with .I hate F3 architecture .The more i am reading the more i hate these drives .

Ps : Have changed to hate typo please
