WinExplorer shows incorrect drive size,.. sort of

Archived from groups: microsoft.public.windowsxp.general (More info?)

Hi, I just bought a WD 250 gig drive from Costco. The only thing I ask
in life is to whack this thing up into 4 partitions; One 10G and three
80G under FAT32. The 10G is a boot partition so I can move the OS in a
day or two, the rest are extended.
No FAT32 option in XPsp1 "Disk Manager" so I boot a CD version of the
ME floppy and do said same. Everything goes as well as can be expected
except,.. the last 80G partition is only recognized under XP Windows
Explorer as 10G. In Disk Manager it shows as 79something G. They all
are listed as "Healthy".
In FDISK everything is ok 10, 80,80,80 but when I FORMAT the last one
it say's "Formating 10,445MB" or something- it's only using 10G.
Is there a 3rd party overlay that works around some kind of drive size
barrier?
Notes:
The utility CD that comes with the drive doesn't recognize a USB
mouse. The Tab and Arrow key responses aren't programmed correctly.
(unbelievable but TRUE! stuck loops, loops that exit to the wrong
screen). I don't have a regular mouse handy so that option is out.
Partition Magic doesn't work; hangs on reboot after it does it's
thing. Can't use the Magic Floppy because my PC has no floppy drive as
they've been obsolete for about 4 years. No option to make a Magic
Boot CD here. duuuh.
I use FAT32 because I can recover data from a crashed drive. NTFS
won't let you do that easily. I have a stand alone pc and I don't need
to hide files from anyone. Any hope for the Data rich but Bios poor?
