Bios recognises the drive correctly. I have three primary partitions, one extended partition, and my unallocated space.
I might just ditch one of the smaller partitions, and see if I can then work with the unallocated space.
I think I might give up on all this partitioning in future - far better things to do with my time!
Now- does anyone know how to get your home network working after installing SP2. It was working fine before SP2. Bl**dy Microsoft...
