MJM Data Recovery

Western Digital ROM Recovery A recent job received was a Western Digital 2 TB drive. It had been to another data recovery company before we saw it and they were unable to recover. We examined the drive and found that the processor on the controller card (circuit board)  had failed. Another problem was that the ROM ( this device contains information about the drive and is unique to every drive ) was embedded in the processor meaning that another technique (aka Hot Swap) has to be applied in an attempt to read the system area on the drive. This gave us access to the system area where we could access the modules used to create a ROM. So far so good. We then hit another problem, all of the ROM modules were completely empty so it was impossible to rebuild the ROM using standard techniques, this we believe is the reason the other company could not recover. This did not stop us though, at this stage our senior engineer was given the job and taking the drive we used for the hot swap
