I just bought an Ultra ATA 133 hard drive. It is the 250gb 16mb cache from Maxtor. Someone told me there was a difference between UATA and ATA. I was hoping to use this drive as my OS drive since it had a huge buffer. My motherboard is an Asus a7v266-e. I see these specs..."Ultra-DMA 33/66/100 " Am I going to be able to use this drive? Am I going to be able to use its full potential? Thanks.
