I wanted to get this solution on record here because when I was having problems with my eSATA drive, I searched the website and didn't find this solution. In fact, after an extensive search of video, ASUS, ACOM and other related forums, I finally got to this solution via the help desk at NCIX.COM, the people who build me my editing computer.
THE PROBLEM: my external drive, an ACOM 750 Gb eSATA drive (back up), was preventing WINXP from booting. At first, it simply refused to accept a write, then it prevented the boot. I could only boot with the drive off and, of course, the eSATA is not a PNP device - it needs a boot to work. So I tried my two other ACOM drives, both 1Tb, and they didn't work either. So I swapped the cable; no go. On my non-editing computer, on which I installed an eSATA card, the cables and drives worked fine. So I figured it was my ASUS P6T m/b with the built in eSATA connector. Oh, BTW, when the m/b ships, eSATA is not enabled in the BIOS.
THE SOLUTION: unhook all the USB connections, boot up, shut down, reconnect everything and all is well.
