Hi, first time poster. I'd like to use the utility created by MDGx (posted Apr 2) but think my circumstances are slightly different from the standard, so wanted to check with the experts first before proceeding. When I initially setup my Gigabyte P35-DS4 motherboard 1.5 years ago, I installed WinXP Pro and enabled RAID with the Gigabyte-provided ICH9R driver via diskette. Things have worked just peachy since then, but now I wish to disable the motherboard RAID and just go with AHCI. After deleting the RAID volumes and changing the BIOS from RAID to AHCI, Windows won't load. I get to the black screen with the Windows logo for a few seconds, then the machine restarts. If I switch back to RAID or IDE or Disabled in the BIOS, I can get into Windows. But I want AHCI. Under the RAID settings, the Device Manager shows Intel ICH84/ICH9R/ICH10R/DO SATA RAID Controller under SCSI and RAID Controller. There is no AHCI driver showing under IDE ATA/ATAPI controllers. Do you think I can just run MDGx's utility and be OK, or will there be issues since I've already enabled the RAID? THANKS
