i have the WD5003ABYX running with W7 64-bit with an ASUS M5A88-M motherborad.
i tried to set, in the BIOS, the drive to mode AHCI, but then it will not boot. i tried to see if i needed to change the registry, but the setting in there is 0, as it should be, for the AHCI setting.
things work fine in IDE mode.
any idea what to do, short of doing a clean W7 install?
