The problem I was having was that the system seemed pretty thoroughly convinced that there were no drives sitting out at the end of the SATA connector. I wondered if the problem was that I needed to run the management software that came with the unit, but that required a serial port on the laptop, which I don't have.
So I went out and bought a USB to Serial Port adapter. Unfortunately, the software recognized that there was a port there, but was equally convinced that it wasn't really a COM port. Grumble. That device goes back to CompUSA tomorrow.
After some more futzing around, I finally decided to connect the RAID box via USB. It installed, but there still weren't any drives. But when I went to the system management console, it saw the disk sitting there. So I partioned the disk and formatted it. Two plus hours later, the format was finally done and the drive was visible. Yay! Of course, it was on USB, not on the faster SATA via CardBus connection. Well, let's try unplugging the USB connector and plugging in the SATA connector.
Victory! 300 plus gigabytes of mirrored SATA hard disk appears and disappears as I plug in and unplug the connector.
That'll hold a few recording projects. Now if I just had the Project Mix I/O interface, I could give this a try.
