Backup before you try it.
Buy/shop for a recent but inexpensive copy of Partition Magic, Partition Commander or similar.
Only programs like these will allow you to reallocate the space between partitions on a single hard drive with minimum risk of losing your data.
Another alternative might be to just move all your DATA to the 2nd partition .... I use that method to get separation between my OS/Apps on C: and my data which is always on D: The one bebefit it can you usually format the C: partition and reinstall the OS and the APP without affecting what's on the 2nd partition, D:
I would like to partition a hard drive. I have a 80 GB hard drive, separated into two 32 GB drives. One is a drive with nothing on it, while the other is Windows and files. I would like to shrink the drive with nothing on it by 10 GB, and add that 10 GB to the Primary Windows drive. Can someone tell me how to do this with Windows "Disk Management Console"?
