I'm using Windows XP x64 Edition, and connecting the drive using USB 2.0. Windows cannot identify the new hardware. Under device manager it has one of the yellow question marks. The drive has been formatted and partitioned. If it's a driver I need I can't find one anywhere, and Lacie barely mentions the driver saying it's plug and play in their manuals, like Windows should just recognize it. The only thing is, Windows doesn't. Previously I used the external hard drive with the firewire interface (Windows XP Home) and everything worked great. Any help is appreciated.
