i have a small problem with my WD 40GB PATA HDD (actual: 37GB).

long time ago, i created 3 partitions. C: 12GB, D: 12GB and E: 13GB.

now, i format my pc. i plan to delete D partition and C partition. so that i have an unpartitioned space of 24GB. i wanna make it into C: for games and windows.

here comes the problem. after i delete both partitions, i still get unpartitioned space of 12GB and another unpartitioned space of 12GB. they don't combined into 24GB like i expect them to be.

why??
is there a way to fix it?
