Seagate drive with a suspect non original ROM chip. Have dumped ROM but not sure how I can identify what its come from, if its not original. Can't see any useful plain text in hex viewer.

The ROM is corrupt.

Thank you! Yes so that's a completely different model to what it's supposed to be so indeed non original ROM.

It's a company up the road from me that if you reject their repair quote they sabotage your hard drive.... 3rd case I have had in off the back of them in the last 12 months. The first one I noticed they had replaced the ROM with a MOSFET.

I have attached the adaptives.

Edit: Our posts crossed, so it appears that the adaptives are not required.

Hello,
what's the model of the drive?
I might be able to help with it, however, i think recovering from this situation will not be cheaper than the original quote...

Hi friend .

What utility do you use to analyze Seagate F3 roms?

A few days ago I found your utility for WD wdROMv12.exe and it is fantastic.

Thank you

Version 15 computes the checksum of the more recent boot blocks, whereas v12 does not:

WDnewROM analyses the latest WD ROMs (new native WD architecture).

This is the tool for Seagate ROMs (written by @E123):

Thank you very much for your fantastic profits.

And thanks also to @E123 for the seagate one.

Hey fzabkar,

Sorry if this is off-topic as I'm a bit new. I have a ROM dump of an OEM Seagate 10K 2.5" SAS Drive. Is there a way to generate an LOD file from this? I have compared the LOD header from other oem firmwares of similar Seagate drives, so I understand that the first 250k (roughly) bytes deal with the LOD header. Any advice is appreciated on how to go about this. I can't PM you yet, so I thought I'd ask here since Seagate dumps are being discussed. I know how to modify the hex code, but not sure how to read the dump. I can upload it for you if that helps. Thanks for your time and help. If you need any further information from me, let me know.

@E123 has written a LOD editor for Seagate SATA drives. I don't know if he has done the same for SAS. However, the LOD file, at least for early SATA models, normally consists of 4 overlays which live in the SA rather than the ROM.
