Thanks in advance!

Hello!

Maybe you can use this one!

Thank you for replying AdrianSRD!

But for my case it needs to be FW JC45
Yours is JC4B, won´t help this particular case

Anyone else have ST3500413AS - FW JC45 ??

Thanks in advance!

Take a JC4B ROM, patch your patient's SAP/RAP/CAP adaptives into this ROM, write it to the PCB, and then start the drive with the JC4B loader. If you can now access the SA, then retrieve the SA modules and tracks, create a JC45 loader from the drive's own resources, restore the original JC45 ROM, and there you go.

here you go

Hi
if its not work and still you need the LDR.

Then tell me your hdd product number i will give you LDR.

Case solved

Thank you all, specially jermy for providing the requested LDR !!!

@fzabkar
Your suggestion to re-create LDR from SA was very astute.
As soon as I have some spare time I´ll dissect one LDR to find it´s data offets in modules and tracks.

Thank you all again.

*** CASE CLOSED ***

I think my method needs some refinement, but I've dissected a loader here:
