Hello guys,

I need help replacing the board on my SSHD ST1000LM014 with liquid damage.

The plan:
1. Secure Erase of the donor drive with a Seatools USB Stick and the option "Overwrite Full".
2. Transfer of the ROM from the patient to the donor PCB (with a CH341A ROM reader, an 1,8V adapter and an Pogo Pin WSON 6x5 adapter).
3. Swapping the PCBs.
4. Init of the NAND using the diagnostic port with the command /O and I.
5. Restarting the hard drive.

I base my plan on these two posts:
https://forum.hddguru.com/viewtopic.php?f=1&t=39477
https://forum.hddguru.com/viewtopic.php?p=251854

The Hard Drive Informations:

Patient Drive:
ST1000LM014
Date: 15085
Site: WU
P/N: 720278-002
SN: W382FQW1
PN: 1EJ164-021
FW: HPM6

Donor Drive:
ST1000LM014
Date: 14515
Site: WU
P/N: 720278-002
SN: W3823AG9
PN: 1EJ164-021
FW: HPM6

Now I have these questions:
Do you think my plan is realistic or would you do something differently?
Do I have to pay attention to something?
Can I try to read the ROM with a 1,8V adapter or should not use a adapter and try it with 3,3V?
Is "Overwrite Full" the right option for the secure erase or "Erase Track ZERO" or
should I use a other secure erase tool?

It would be very nice if someone could help me.

Hello again,

I did a secure erase on the donor drive with hdparm (It was ready after about 3 hours).
After that I transferred the ROM (It worked with a CH341A, a 1,8V apdapter and a pogo pin adapter).
And after that I swapped the PCBs.

The drive is now spinning but the computer does not recognize the SSHD.
The terminal say:

Code:

Rst 0x40M
Servo Processor Is Reset. 

(P) SATA Reset

 Waiting drive spin up 

(S) SATA Reset

 Waiting drive spin up 

 Waiting drive spin up 

 Waiting drive spin up 

 Waiting drive spin up

...
Everytime I click Ctr + Z comes: Waiting drive spin up.
But if I click on Ctrl + Z immediately after connecting the SSHD, I am in the F3 terminal for a short time.
It looks like this:

Code:

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

 Request spin / disc table recovery
ASCII Diag mode

F3 T>
Set Transfer Mode selected
PIO selected
Set Transfer Mode selected
Ultra DMA selected

SenseCode = 03310000
ReadyStatusFlags = 0002A181

 ABORT!
OpCode = 00000060
SenseCode = 03310000
ReadyStatusFlags = 0002A181

Unrecoverable Read Verify Error Reported

Any idea how I can run the command "/O I"?
Or any idea how can I go on?

Double check the patient rom contents against the rom now on the donor. When you say liquid damage - how bad is the original board?

Hello Lardman,
thanks for you answer.
I saved the ROMs on the computer in .bin files.
The hash of the ROM file now on the donor is the same like the file from the patient ROM.
So I think the ROMs should also be identical.

As I can see it is the orignial board only slightly damaged, but it has a dark through hole.
I heard it was only little liquid.

PS: I post the two ROM files below.

I hate these drives - you may have more than just a board problem. Someone with a higher success rate with these will be able to confirm.

Upload the attached rom - see if it gives you terminal access.

Lardman,
Many thanks for your help.
I don't see how mechanical damage could have occurred because there really was very little fluid and no other problems.

I'll try the patched ROM right away.

I tested the patched ROM and now I have access to the terminal after pressing Ctrl + Z.

I tried to init the NAND with "/O and I" but after reconnecting the SSHD Windows still says "No media".
This is the terminal output:

Code:

 Request spin / disc table recovery 
ASCII Diag mode

F3 T>/O

F3 O>I

ALF Parametric Tables Preserved

Flash was erased and ALF Tables have successfully been initialized
F3 O>

Is the drive seen in the bios and is it shown as the correct size.

No, I don't see it in the BIOS and Windows shows the drive only with 0 bytes.

Fesiplatio,
after initialization NAND, you need to write the native ROM

But the drive is ID'd correctly? I thought it would have given the full drive metrics and just blocked UA access. As Tomset say rewrite the original patient ROM back and give it a power cycle.

The drive is also not properly identified.
This is a screenshot from the windows explorer (in German).

I'll change the ROM again right now.

Lardman and Tomset,
Yes, wow it worked.

I changed the ROM again to the original patient ROM and after reconnecting the SSHD, I have all data back.
Thank you soooooooooo much.
I've been busy with this hard drive for an extremely long time and now it worked.
You really helped me alot.
Many Thanks.

Well done Lardman, Tomset. Glad it worked out for him.

I can see from another forum the OP has been trying since the start of the year to get help with this and has done a lot of research on getting another drive with the same FW and finding a way to read off the ROM and also researching the terminal commands.
