Hi Tim,

I am afraid that I do not know how to change my partition type. I can confirm. however, that the BIOS is set to Auto / LBA and that BIOS confirms UDMA 5 is set (and cannot be set unless the correct cabling is detected).

But is my controller, though detected as a PIIX4 (and described as such in the Asus manual), really a PIIX4? lspci :

On the other hand, cat /proc/ide/piix :

                               Intel PIIX4 Ultra 100 Chipset.
