When my 250GB USB hard disk drives (HDDs) arrived they were formatted FAT32 for greatest compatibility. I've been playing around with the different HDD formats that the NSLU2 R63 firmware now supports (NTFS/FAT32/ext3). When I came to return the drives to FAT32 for a new test, I was surprised by just how hard this was to do under WinXP. The complete issue is covered, and a utility to format large volumes as FAT32 under WinXP can be found here http://www.ridgecrop.demon.co.uk/index.htm?fat32format.htm. Just spreading the experience.
