I have a small Apple Western Digital 20 GB hard drive that I would like to use as a backup for my wife's Dell Latitude laptop running XP Pro. I used the Apple Disk Utility to partition drive with the MS-DOS file system. The Disk Utility says it is fine. It is in an external case and my wife's Latitude cannot find the drive. Is this a PC issue or did I screw up the drive using he MS-DOS File System option in Disk Utility? Dick
