Two 500Gb Hard Drives
I have 2 500Gb ext hdds. One of the drives contains my original files and the other one contains their backups. These are the only files on the drives.
One drive has 4.58Gb of free space left and the other one has 60.1 Gb left.
I checked the files on each drive and there are no files missing on the drive that has 60.1 Gb left. They both have the exact same files and each file on both drives are the same size.
The drives aren't the same type. Could one drive be reserving space/be partitioned for backups or something else? If so, how can I find out and, if not, how can I find out where the drive's 55Gb has gone?
