I am attempting data recovery on a WD10SPZX drive using a PC-3000. I performed the following steps:

1. I read the ROM from the IC using an external programmer and saved a backup.

2. I used PC-3000 to unlock the sed lock with this backup.

3. I then soldered the ROM IC back onto the PCB.

The Problem: Now, the drive will not turn on and spin up, and the PC-3000 shows no activity lights. Rewriting the original ROM file back to the IC results in the same issue, leading me to believe my programmer may have created a corrupted backup.

Additional Info: When I try a different ROM file, the drive does spin, but it shows no model, serial number, and 0MB capacity.

The data is critical. Could you please advise me on how to proceed? Thank you

A caution for the future is to not modify the original batch. Always work with a replacement ROM chip.
What programmer did you use?
Include the original ROM dump on forum.

The process I just saw in that group for hard drive repair was very different from the method I've always used. If you can, could you help me out?

You have PC3K. I don't have anything other than a tool that I wrote to assemble the ROM from the modules that you recover from the SA (0x109 and 0x129). If you upload those modules, I'll rebuild the ROM for you.

You wouldn't be able to do this. You would receive a response from the PC-3000: Rom data corrupt. Sections CS error .

109 is OK, but I need 129 (or 130 ?) as well.

I just ran the search again that I posted to include nested modules and 129 was still not found. It can only be found by ID.

I don't know why, but the PC-3000 was able to unlock my corrupted ROM without showing any errors

I couldn't find that module. Instead, I've zip all accessible modules from the donor drive and uploaded the archive to a temporary site

I can't find any backups of ROM-resident ROYL modules. Try a full track dump.

Hi,
Modules 129 and 130 are not described in DIR.
These modules are described in ATA Ovl.
These modules can be read by ID.
Ctrl + Alt + 3 -> see photo.
To read these modules, ATA Ovl must be loaded into the memory.

With such limited knowledge, the easiest way is to find a drive with a very similar production date and get the ROM from it.
