Hard drive names change on Win XP Pro

F: (NTFS)
H: (FAT32) (a USB drive)
E: DVD drive

You can use Disk Management to do that pretty easily. Refer to this article for how-to details:

What you wanna do is remove the D: assignment from the DVD-RW, then change the NTFS F: assignment to D:, and then assign F: to the DVD-RW to complete the swap. You'll have to reboot once or twice during this process to free up the drive letters.
