Can anyone verify is this 2 patient drive and 2 donor drive , any one of them is compatible for Head swap

I see head swap as being tricky at the best of times due to risk of damage to the plattens. 2 plate drives may be easier but I use 8 to 11 plate disks.

The head swap should be safe enough but watch swapping logic boards as some are incompatible due to differing ROM settings.
