I got a 320GB harddisk, which was partitioned into C: and D:, the C: was used to be the OS, and D: contains other stuff.
But now I bought another harddisk which is 1TB, now I want to combine C: and D: so that I only have 2 drives for simplicity reason.
Can it be done without damaging the files in drive C: and D:?
The os is Win XP.
