Listing is for a hard drive circuit board (PCB, Logic board) ONLY. No hard drive is included! Due to large PCB quantity available, actual PCB received may slightly vary from the one pictured. This hard drive circuit board is inteded to be used for data recovery or hard drive repair purposes. To be sure that a replacement PCB will fix your hard drive, follow our hard drive diagnostics guide. Be sure that this part is compatible, by going over the Donor Matching Guide.

Most of the hard drive circuit boards contain unique information in ROM "memory" chip. That information is mandatory for proper hard drive operation. ROM chip, or it's data, must be transferred onto new circuit board. If it is possible to move the chip over onto new circuit board, a local computer professional should be able to handle such a task. For our clients, with a purchase of $60 or more, we offer complimentary adaptation service, which includes either moving ROM chip onto new PCB, or reprogramming new circuit board with correct ROM data.. If you intend to perform such a task yourself, get familiar with our PCB Replacement Guide.

In cases where a simple circuit board replacement does not solve your hard drive issue, we offer a special PCB Replacement Service that should take care of all your needs. Simply visit the Adaptation Service page for additional details.
