I have a PowerEdge T620 with a PERC H710 with 4 physical disks (and 1 hot spare) in a RAID 5 configuration.
See attached screen-shots for disk layout.
I'm running out of space on the C: drive, however (thankfully) the data on E: is not needed. I'm guessing since it's adjacent to C:, this makes it easier to re-size the C: drive. Note that the data on D: is important, and can't be lost. I do have backups, but would prefer not to "need" them.
What's the proper way to take the space on the E: drive and incorporate it into the C: drive?
