Setting Sata HDD to ACHI post Win7 install?

Hello,

I purchased a new computer utilizing the P6TD Deluxe Asus motherboard.

It came pre-installed with Win7 Ultimate. However, I noticed in the BIOS that it set to be treated as an enhanced IDE drive rather than a sata one. When I try to set the mode to AHCI, the drive fails to be recognized.

I have been told that it needs to be configured as AHCI prior to installing any OS. Is this true?

If so, what program would you recommend that would enable me to create a mirror of the contents within my drive that can be restored after the drive is reformatted and then set to AHCI so I don't have to go through the painful motions of reinstallig and configuring all my software?

Thanks.

According to Intel (here).

When you re-install the OS using ACHI for your HDDs, you have to re-install your programs too.

Thanks.

No, You just change the Msachi setting in registry from 3 to 0 and reboot. New drivers are installed for SATA and it will work fine. I just did it.
