Strange very large disk partitions behaviour !!!

Hi kernel developers,
I have a RAID disk enclosure that contains 16 IDE disks that is
seen via its SCSI interface as a very large disk sliced in 3 QUASI
IDENTICAL partitions, here is the fdisk information:
[root@nfs00 root]# fdisk /dev/sdb
Disk /dev/sdb: 2199.0 GB, 2199014866944 bytes
64 heads, 32 sectors/track, 2097144 cylinders
Units = cylinders of 2048 * 512 = 1048576 bytes
Device Boot Start End Blocks Id System
/dev/sdb1 1 699048 715825136 83 Linux
/dev/sdb2 699049 1398096 715825152 83 Linux
/dev/sdb3 1398097 2097144 715825152 83 Linux
So I formated each partition ext3 ( that went ok) and monted the beasts:
[root@nfs00 root]# df
/dev/scsi/host2/bus0/target0/lun0/part1
1008G 33M 957G 1% /mnt/p1
/dev/scsi/host2/bus0/target0/lun0/part2
672G 33M 638G 1% /mnt/p2
/dev/scsi/host2/bus0/target0/lun0/part3
672G 33M 638G 1% /mnt/p3
[root@nfs00 root]# df -k
/dev/scsi/host2/bus0/target0/lun0/part1
1056887972 32828 1003168364 1% /mnt/p1
/dev/scsi/host2/bus0/target0/lun0/part2
704592112 32828 668768028 1% /mnt/p2
/dev/scsi/host2/bus0/target0/lun0/part3
704592112 32828 668768028 1% /mnt/p3
Now I'm really confused, the LARGER partitons are showed SMALLER
then the smaller partitions and why that enormous difference, what I'm
doing wrong, I've fsck each partiton and all seem to be OK, I'm afraid
of an integer overflow or such thing that can blew the whole storage or
I'm too tired and overlooking something.
Please help me while I'm still having some hair left TIA.
Best regards,
Mircea Ciocan
