Seagate ST1000LM014 here that is unresponsive, no power or signs of life. Is PCB swap with ROM transfer enough on these or does the NAND flash also have to be transferred?

The following thread suggests that, at least in some SSHDs, one could perform a secure erase on a donor drive, thereby clearing the donor's NAND cache, and then transfer the patient ROM to the donor PCB.

https://www.data-medics.com/forum/st1000dx001-t1732.html

Would it be worthwhile to check the PCB voltages? I could help you with that if you could provide a detailed photo.

Try and post a terminal log

This is a known issue. Copying the rom as suggested will probably not work. But would need to see terminal log as pcimage says, to see what is reported.

We can recover from drives with ssd side problems and corrupt rom. But are based in the uk, I would recommend data analysers if you are based in USA.

In edit: rom replacement may work if ssd or pcb has failed.

The link fzabkar posted (https://www.data-medics.com/forum/st100 ... t1732.html) suggests that locating a donor drive, performing a secure erase command on it, and then swapping PCB + ROM should be an option for these SSHD models.

Can’t say I’ve tried that method, but can see the logic. Whether it works or not I don’t know.

I've located a matching donor drive, when I receive it I will test and report back.

Try the "Q" command. This should list all the terminal commands available for your HDD. Maybe there is a command to initialise the NAND.

Received the donor drive and proceeded to initiate a secure erase, however a fluke power outage (should've been on a ups, i know...) interrupted the secure erase. I tried to re-initiate the erase but it now fails immediately. Drive still responds to smart diagnostics but all attempts to read or write data now fail. Again this is the donor drive, not the original. I did do a test swap of the ROM and the original drive does spin up and respond to diagnostics but data can't be read.
Terminal output on donor does allow access to F3 T> prompt:

Rst 0x40M
Servo Processor Is Reset.
(P) SATA Reset

Request spin / disc table recovery
ASCII Diag
TCC:001D

You secure erase tool has set a password on the drive. This default password should be listed in the docs for that tool.

You are correct. I realized that was the problem but had been issuing the wrong command, hdparm --user-master m --security-unlock password /dev/sdX which returned an error SG_IO: bad/missing sense data. Of course that was trying to unlock using master password.
The correct command was a simple hdparm --security-disable password /dev/sdX which did the trick. Drive is now unlocked, hooked up to UPS, and performing a secure erase. I'll update with results of the ROM swap once that's complete.

OK. Secure erase completed on donor drive. Swapped ROM over and the original drive spins up but reports 0MB size with no SMART data reporting. Terminal output reveals the following messages:

ALF Parametric Tables Preserved
Flash was erased and ALF Tables have successfully been initialized

and bingo, a power cycle later I have access to the data. So seemingly the secure erase wasn't necessary after all? Interesting side note-- the donor drive actually worked with the ROM chip from the original drive. Perhaps adaptive information is not stored on the ROM on these models?

I examined a ROM dump from an ST1000LM014 in the files section. It has the usual CAP, RAP and SAP segments. There is an interesting additional section at the end, though.

Can you provide ROM dumps from your patient and donor?

Did the donor PCB you used come from a drive with the exact same firmware revision as the patient? Do you think this is a necessity?

Well,
Secure Erase Does Work if Few Parameters Are Taken Care But Now We Have Methods Known Now That Will Help Init The NAND .
