This Sony Vaio came with the 40GB HDD split almost evenly between C: & D:. I'll never have a reason for multiple OS. I don't have any good reason for a partitioned drive, that I know of. Having to direct all data to D: is a royal pain, especially since this is a family PC and no one is particularly adept.

I backed up all the data on D: and removed the partition. Now I can't seem to merge the unallocated space with the primary drive. I have been trying to do so in Disk Management, but to no avail.

How do I merge the unallocated space with the Primary Drive?

Running WinXP.
Please help,
Chris
