Just so I understand, DrivePool first matches the folder structure, and then computes hashes of each file to identify duplicated data, correct?
So I can have multiple drives with the same folder, e.g. \pics, and when they are added to the pool, DP will then ensure there are 2 copies of the data on different physical disks, and it doesn't matter how many disks the original files were on.
e..g.
disk 1 - \pics\file1 - 1000
disk2 - \pics\file1-500
disk3 - \pics\file501-1000
When I add all 3 disks, then after hash is calculated, no files will need to be moved, since 2 copies exist on 2 disks.
