I understand what you are saying, Brent, and I have dealt with drives like that before.? This is different.
?
What I have is essentially the same as what you above called "WD Cavier Green bare HDD" however, instead of the flat SATA interface, there is a USB socket on the board.
?
I have this morning removed the PCB (the green board in Brent's last photo) on the failed drive and replaced it with a known good one.? The drive spun up, as before, but this time it tried to fly the heads - and failed.
?
I have to conclude that the platters and the interface board are dead, a double fault (which does happen but I find suspicious), and I find it interesting (that is to say, I don't have an explanation) that the disk performed differently with the two interface boards.
?
I'm now wondering whether the formatting information may account for the difference.? The known good interface board came from an NTFS formatted disk, the failed disk was HFS+.
?
Having carefully reassembled both disks, I think I'm now looking at another attempt to exchange the boards after having reformatted the new disk as HFS+.? But not today <smile>.
