I have a 100gig and a 60gig hard drive in my system, both are western digital.they are formatted fat32 - full partition.Windows XP see's both drives as 100 and 60 gig an fat32. ( TO DO THIS )if ? you are useing western digital or maxtor hard drives,go to western digital site an download (Data Lifeguard Tools)this is a disk format tool, an put it on a floppy disk, it is free.with floppy disk in the drive reboot,when data lifeguard boots up follow eash step you are doing ( except for )when it ask you if you are installing xp say (no) even through you are installing xp, you will need a windows 98 boot up disk so it can copy the system files to make your drive bootable an fat32. it will all so ask you if you wont to make the drive full partition say yes,all so it will ask you if you wont to keep the fat32 say yes if you are playing a lot of games or using older software,the ntfs file system is not very friendly. when done reboot,your system should now see your drive as a full drive an fat32.PS:if you have more than 1 drive be sure you do the right drive.
