i would be surprised if you will ever get it to work.
the reason is windows 98 uses FAT32 file system, and XP uses NTFS file system. neither will talk to each other, FAT32 simply does not understand NTFS (a bit like you speaking to someone abroad who has never heard english before)
best bet is to upgrade your windows 98 machine (assuming thats possible - run a sysprep prior to upgrade) to xp, and then convert the fs to ntfs - if you need help doing that post here, once you have confirmed your windows 98 machine is capable of handling XP.
Alternatively, lots of CD's :oP
