I just got a USB2 external kit. It works great, but the IDE cable inside of it only had connectors for one drive. So I slapped a two drive cable in the setup, and put a master and slave on the channel. Fired up WinXP, and no luck.
It only recognized the master. Bummer. Just for reference, I got this unit from www.buyaib.com. I don't know it's make or model number, but it's the one that sells for $29.50 for the retail package.
