As we all seem to be having difficulties head swapping these, I though it'd be nice to have a thread to share our DM head swap experiences. Here's mine from today:
Patient
ST30000DM001
PN: 9YN166-570
FW CC9F
Date: 13044
Site: TK
Serial: Z1F0Y...
Donor
ST30000DM001
PN: 9YN166-570
FW: CC9E
Date: 12433
Site: TK
Serial: Z1F0K...
As you can see, I matched model, site, PN, and first four of serial. The drive initially ID'd showed correct capacity and allowed sector access. Resources were backed up and imaging started. A few heads actually read relatively quickly, others were slow but steady with only a few bad sectors. After about 10 minutes, drive hit a bad sector, began clicking and failed to ID after power cycling it. :x :x :x Now it just clicks and spins down. But at least I know the heads were compatible, and I didn't kill them in the swap.
