I have 2 HDDs:
1. SATA - C: with Vista (32Gb), D: for data (40)
2. USB drive - G: for backups (32), H: for data (200)
E and F are for DVDs.

I want to perform Complete PC Backup, but when system wants me to select the
destination i have onl D and H on the list! I would like to select G.

The strange is that on the next screen C and G are both marked (and the
checkboxs are not active so I cannot unselect G) and right after their names
there is "(System)".

Swap file is solely on C drive. I don't use system restor on G. How to fix
this?
