I have never seen any problems with disc sizes in XP.
Try running diskpart (from command line) then use LIST DISK to see if it treats the missing space as free space or not. If it does, try booting from an NTFS boot disk and running DISKPART.
> DISKPART
DISKPART> LIST DISK
DISK ### | Status | Size | Free
---------------------------------------
Disk 0 | Online | 136 GB | whatever GB
DISKPART> SELECT DISK 0 (provding disk 0 is the disk)
DISKPART> LIST VOLUME
(as above but volumes..)
DISKPART> SELECT VOLUME 1 (providing 1 is the volume)
DISKPART > EXTEND
It should then extend the partition to the full size...
