I have a Windows 2008 R2 server with Disk 0 partitioned as:
94 Mb - Home Partition
Recovery - 3.00 Gb NTFS Partition
OS C: - 40 Gb NTFS Partition (less than 1 Gb free)
DATAPART1 (D:) - 1072 GB NTFS (455 Gb free).
I just found the 'Shrink Space' option in Disk Management. When i select Shrink space for D: it will allow me to shrink the disk by up to 378872 Mb. I'd like to reduce the size of D: by 10 Gb and then increase the size of C: by 10Gb.
Is this safe to do? Can I do it while in production without affecting users?
