OK, so we expect this is a genuine PUIS issue. I assume you have already tried using HDAT2 to reverse the PUIS flag, but it reports that PUIS is
not enabled even though you know that it
is enabled (which is the known WD bug).

I assume you are refering to the SATA
controller, not the drive (hdd).

That's interesting. This is not a motherboard support forum

but I checked the Asus website, and that motherboard has 2 x PATA and 2 x SATA ports. Look in the MHDD manual webpage - for controllers in IDE mode, MHDD only supports the primary (0x1Fx) & secondary (0x17x) PATA I/O addresses. Even if you put the SATA controller into IDE mode, which I/O address will the SATA controller use? Perhaps it is using a different I/O address, especially if the motherboard PATA controllers are still enabled...? That could explain why MHDD does not show your drive.
Somehow you have to find a motherboard & SATA controller configuration that will allow MHDD to recogise your drive, otherwise you cannot use MHDD to attempt to use
guru's fix (obviously). If I was in your situation, I would be looking at the options available for your motherboard to disable the PATA controllers and to configure the SATA controller (in IDE mode) to use either the primary or secondary PATA I/O addresses. That's all I can suggest
