I'm using Service Pack 2 of XP Professional.

As far as the Drivers, someone else suggested the same thing on another forum. I went to the Sabrent website (the maker of the PC card) and download and installed the drivers. I think that made it worse, because now I can't access the drive at all. I heard the little "ding" that tells me I plugged something in, but the drive doesn't show up in My Computer. But when I plug it into the back USB ports (the 1.1's that were on the laptop initially) it works right away.

As far as backup software, I'm not using any. Just copy and pasting.

Thanks.
