Hi there,
I have two fried PCBs of 2x wd 6401AALS black edition that were working on a Raid1 config.
Board Number: 2060-701567-000
Main Controller IC: 88i8845E-BHY2
HDD Motor Combo IC: L7251 2.2
Western Digital PCB 2060-701567-000
I have got the replacement donor PCBs available ail but have no idea how to replace the main controller (BGA) from the original to donor PCB or swap the Motor controller which is damaged from the donor to the origianal PCB.
Any company that could provide the service to swap the ICs with a price quote?
Thanks.
Steven
Let me rephrase my question because i received a lot of ... you need a professional type of advice and no actual advice ....
The SMOOTH chip is damaged on the side that drives the spindle motor. The side that controls the board's switchmode power supplies, including the Vcore and Vio supplies for the MCU, is not damaged, so I would expect that the MCU has probably survived.
The "ROM' on my board can be reconstructed using commercial data recovery software. Software that can accesses the hidden System Area on the platters and retrieves various firmware modules which are then reassembled into a ROM image which can then be written to the MCU's flash memory. This is a simple, single-click procedure which requires no soldering.
That said, some firmware versions do not have the required ROM backup on the platters, so the procedure in those cases may require an MCU transplant, or some other software method which I don't know about...
So.. does anyone know a reliable and reasonable cost vendor for a ROM reconstruction or if that fails MCU transplant ....
