extern hard drives

[Doug Pollard]

HI All,
    I have a dual boot system with xp and ubuntu8.04  running.  I also 
have two usb hard drives with media on them.  I formatted them with 
gparted as fat 32 with the thought that I would be able to read with 
ubuntu and xp.  Xp cannot see either drive. Does any one have any idea 
why Xp can't see the drives.  Xp is using ntfs should it be able to see 
and read fat 32 drives??
