But Windows File Explorer does not seem to understand what has happened. Intels's "Rapid Storage Technology" status utility sees the drive go and a new drive appear. I have not seen Win XP handle a swap of the drives yet - I had to re-boot Windows anyway. However, I don't know if this AHCI mode is worth the bother.

Granted, the BIOS rev is 1002 and there is a 1008 version available, but when I tired to upgrade to it, I got an error that it was not an "EFI" BIOS and I have not figured out how to "fix" that. It appears that later versions have a compatibility issue with something. This is the driver listed on Asus's support website for this m/b. It may be important to some to know that this is NOT the latest driver off of Intel's website - that driver proved tp be unstable. Under Windows XP Pro SP3 for the AHCI mode I am using Intel's driver "iaStore.sys" version 10. It seems to be two separate hardware entities when I change the BIOS settings between "IDE" and "AHCI" modes. Actually, I think there is two, or one with two physical parts. And inside of that there is a Series 6 Express SATA controller. This board includes the Intel H67 Express Chipset. But have since rebooted so i can put it on record as an Asus model P8H67-M/PRO.

I posted the original while MHDD was running and did not know an easy way to get my m/b model. Live Long and Prosper, unless your handle refers to the process.
