That's mainly because there is non-volatile memory chip on the PCB that is tied to the drive, containing the "adaptive data" for the drive. So you would need to transfer that chip from the old PCB to the donor. As noted, if the data is critical and you're willing to pay for professional data recovery, that is the way to go. But if not, this is likely your only option, so even if not perfect, it's better to risk this than just toss it out. For reasons like the adaptive data and others, you should not plan to merrily continue using the repaired drive, but it may give you long enough life to recover the data. When I did this on vintage drives (where system may need the same drive type to work), I would buy 2 of the same drives, use one for the PCB donor and the other to copy data to once the original is running. I've successfully repaired about a half-dozen drives this way, it does work.

It's a strange feeling to see it come back to life. Good advice, the closer the mfg. date the more likely it is really the same. Oddly though, I've even seen some boards with visually different chip/component layouts work as replacements. --Bob Prosperi |
