To expand on this... The drive that will be used to borrow the logic board needs to have the same firmware, not just identical. The label on a hard drive will show a serial number, firmware number and date of manufacture. Serial numbers should be close, but not necessarily sequential (that's would be like finding a needle in a haystack
). Firmware needs to be identical. If the bad drive has a FW of 1.02 and the replacement drive/board has a FW of 1.03, it won't work. On the rare occasion, it's possible to find a seemingly identical hard drive, with same FW, but the date of manufacture will be far enough apart, that they physically changed the logic board. This again won't work. I've come across that maybe twice in the last 10 years.
There are some companies that buy NOS to sit on and sell in cases like this. There was a guy out here that did that. The prices are not cheap, you'll pay a slight premium for an old drive, but it's a lot cheaper than sending the bad drive out to be recovered - assuming it's a logic board issue.
