Firmware Needed for WD50NMZM-59BDAS1

Have you examined the "hidden" area in the two regions (ABA 0xB99DC - 0xBA89F)?

Code:

ROYL directory module 0x020B found at 0x7DCF6

Active directory flag = 0x02

Identifying SA regions ...

Reg#    Reg size     Reg loc
----  ----------  ----------
0x00  0x000B99DC  0x00000000
0x01  0x000B99DC  0x000BA8A0

The range from 0xB99DC to 0xBA89F might contain interesting stuff. For example, it would contain modules 0x129 and 0x130. These don't exist in the main directory, but they contain backups of the ROM modules.

Module 11 has a table of these hidden modules:

Code:

The table appears to be a template, and the locations of these modules appear to be dummies. They fall within the range of the region template in ROM (0xBD000).
