Partition Magic Rescue Disk creation

I just upgraded to a larger disk. No problem moving data from the old disk to the new one. But when I tried to create new rescue disks I get an error message. It asks for a diskette in drive A;. It checks the disk and then says: “There is not enough free space on the diskette. Space Required: 1457000 Bytes Space Available: 4294967295 bytes Space Needed: 1457001 Bytes” I have tried several different diskettes, all freshly formatted. This is Partition Magic 8.0 and I am running Window XP Prop.
