I have a Lenovo Y500 Laptop. In this I got, 512 MB RAM, 120GB HDD, INTEL Centrino Duo PROCESSOR. Its HDD Partition is C:\20GB, D:\80GB, and remaining part is used as RECOVERY. Windows Vista Basic is Pre installed.

Now when I update windows it cover the whole C Partition/drive. If I re-partition my HDD then I think I lost recovery option also. Which is very help full for me. (I have Lenovo's Windows Vista Recovery Disc also)

Now my real question is that how i8 enhance my C partition/drive area 20GB to 30GB or more. Is there is any software which help me in this matterC:\Users\Dazzling\Desktop\HD status.jpg

Repartitioning your machine is quite straightforward and I normally use Partition Magic for this purpose, but it's now been discontinued.
I have used Partition logic, but it needs to be burnt to a disc for use, but it is FREE
