@locarno, attached is an HDDHackr UNDO.BIN file which I have created from your resource dumps. I have changed only two data records in MOD 02, namely the model number (which had been filled with ASCII spaces) and the capacity. Since you will be using HDDHackr to restore your MODs rather than modifying them, the question of compatibility should not arise.
Please ensure that there is no other WD drive that could become the target for HDDHackr.
WARNING: The attached UNDO.BIN must NOT be applied to other drives, not even the same model or firmware version (01.01A01). Doing so will very likely brick the drive. That's because MOD 02 has an internal version number "00080000" which must match the original firmware.
I started HDDhacker.exe. See HDD. When I started restore UNDO.bin i get this:
Can't write firmware to drive!
