Is it normal for Vista to have my HDD's in Multi Word DMA with AHCI enabled?

I just enabled AHCI on my SATA HDD's. They are Maxtor 1TB 32MB cache's. I have 2 of them and now with AHCI enabled, Vista 32 Device Manger says they are in "Multi Word DMA mode 2". Before they were at Ultra DMA mode 5. Sandra is benching them at like 79MB/sec though so I'm thinking its fine. Anyone?

Download hdtune and it will show you exactly what you got. I think what you seeing there is dvd drive.

oh ok cool thanks. But I was definitely NOT seeing the DVD drive, it tells you what type of disk and it clearly said ATA Disk, whereas the DVD says DVDRW drive or whatever. I'm actually not in AHCI again because I had to Ghost restore due to another issue. But I'll check it out.
