I stuck in my Windows set up disk, deleted the existing partitions, and

Hi David,

Have you upgraded the new (re)install to at least Service Pack 1? I
seem to recall the original XP release did not support 48bit logical
block addressing hence could not address partition sizes above 137GB.

Once you upgrade you can then resize the partition with something
Easus Partition Manager (http://www.partition-tool.com/)
