There is a chance that I can recover data from your drive with lost ROM, but price is around $5K.

It will not help, since all the CP's (except G-List, password, SMART and a few other non-critical modules) are stored in the chip you have lost

I don't think that P-List it's a non-critical module

Furthermore, when contacted about the matter of ROM regeneration, AceLab replied that it would be extremely difficult because :

- It is very difficult to access the surface without the original ROM on modern drives.

- The surface doesn't have a copy of 92 CP (CO).

Curiously, Spildit's own MK8025GAS drive produces this when HRT retrieves CP146:

Code:

Offset(h) 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F

00000000  43 4F 98 FB 40 FC B4 FB 20 FC 00 00 00 00 00 C1  CO˜û@ü´û ü.....Á
........
000001F0  00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00  ................

... and this when CO is carved out of the ROM:

Code:

Offset(h) 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F

00000000  43 4F 98 FB 40 FC B4 FB 20 FC FF FF FF FF FF BF  CO˜û@ü´û üÿÿÿÿÿ¿

The ROM version has an XOR8 sum of 0x00 whereas the other version (from SA?) has an XOR8 sum of 0x81.
