After swapping the ROM to SATA PCB, somehow I was able to read it's SA. at the end some modules can't be read (ROM related). Normally sector can be accessed normally under MHDD, sometime hangs, but a hard reset brings back again to read sectors.

Now at any form when I read ROM, it produces 0 byte file. Tools in use SD Doctor.

What is the valid reason?

P.s: To avoid soldering I need to have ROM read.

i think it's a matter of tools you use . WD doctor have some problems to read some 256k rom and can't read any 512 rom

I read 512K ROM with the tool earlier. but I don't know why it's not working this time.

256K ROM had no issue with 2.5 HDDs, but with some ROYL 3.5", ROM read/write has issue with Doctor, as well as PC3K can't read I heard!

Anyway, re-soldered back.

salvation hd doctor supports this family ?

If you can desolder the ROM, why not place it to a compatible SATA variant?
