I got ST1000LM035 with a burnt PCB.
I changed the ROM and the disk goes to DRD state. However, it does not report an ID.
Does this model have SED?

Terminal show:
Code:
Boot 0x80M
QB
Rst 0x80MSrv DETCR init 0x0000
FTU
PrgF
(P) SATA Reset

RAW OFF
PASS
(DOS Table) Worst Count: 00000000 At SU: FFFFFFFF NT: 00000000 OT: 00000000
MSP213
(MC POR Duration): 000000004F
Intel 6G->3G
Send Status: COMRESET seen
CSpd= 3Gbps
DSC
FAFH_TRIGGER_POWER_UP

yes, that's because device fault is set. And it is set because of donor pcb.
I usually clear it manually or patch the fw so that it does not set it. There is some way in pc3k to do it automatically, but i never used it and don't know how it works or if it works at all.

Is the drive is recognizing that I installed another PCB (from the donor) to it despite I've swap ROM?

Do I understand correctly that this PCB has some extra register stored outside the ROM chip?

I did not research the cause of this problem, just reseted it in terminal and moved on (or patched the fw so that it does not set that flag whatever the problem is). Perhaps it is related to SED and cpu or the log in flash.

It usually works fairly good.
If it doesn't then of course there is manual way to bypass the problem.
