This item is NOT compatible with your hard drive right now. The reason is every single board of this model has a unique firmware, despite what it may say on the drive label.

This item will be compatible after a chip transplant involving difficult SOLDERING, do not purchase this item unless you can solder, and more importantly, de-solder.

We can make the boards compatible for you and take care of the soldering, but we need you to ship the dead board to us. If you would like us to do the soldering, do not purchase this item, but purchase the item in this link.

When to buy this item:

A common problem with Seagate Barracuda 7200.11 drives is that it would suddenly stop being recognized by the computer, or be recognized as 0MBs. Normally, there is a decent chance that it could be the PCB at fault, but with 7200.11 drives, it usually is NOT the PCB, but a firmware problem instead. A data recovery professional is a better choice.

We recommend buying this item when you are sure it is the PCB. For example, if there was a power surge, or some components are obviously burnt, or the wrong power adapter was used to power up the drive. If the drive will not spin up at all, and wasn't dropped, chances of success with replacing the PCB are quite good.

There are no refunds with this purchase, so if you would like to describe the specific symptoms to us, please Contact us through our online form or at, we will try our best to reply within 12 hours.

Item Includes: circuit board, firmware transfer and installation instruction sheet
