actually, it didnt work. It worked at first, but after it completed formatting, it asked me to put in the disk for the RAID driver, then press enter. It was already in there, so i pressed enter, and it didnt work. I tried this several times and it didnt work. I started everything over and it did the same thing. I decided to call alienware, but aparently they are not allowed to sell the XP disks anymore, only Vista :( . Anyway, the tech guy there said that another customer had a similar problem and by replacing the external floppy with a well-recognized brand it worked perfectly. right now I have a Dynex (or something like that), and it was suggested to get an NEC or sony external floppy. Think it will work?
