hello
it sounds as if your hard drive has been formatted with Fat16 which limits partitions to 2 gig in size.
you can recover your full drive size by running boot & nuke (see my signature links)
on the drive, you will lose ALL data on the 10 gig drive. As a precaution make sure any other drives have the power plug pulled from them before using boot n nuke to avoid accidental wiping of the wrong drive.
after you have wiped the drive you can reformat the drive with Fat32 & fdisk if you plan to use win 98 or Win ME
Or you can format the drive with NTFS if you plan on using the win xp OS
keep us posted >>>>> if you need an Fdisk tutorial just let us know
