[…] As a result, while two control boards may appear to be completely identical, merely taking a PCB from a functional hard drive and using it to replace the failed hard drive PCB will give you… a failed hard drive. You may even cause further mechanical damage to the hard drive by saddling it with an incompatible board. If the hard drive gets confused about how it should be calibrated, it could tell its read/write heads to do something they shouldn’t and cause damage to the drive’s heads, firmware, or platters. […]
