May 3, 20242 yr Hi, I need to clarify one point As you can see from my picture below I need to clarify a misunderstanding. Disk 4 is empty or at least should be....in "Main" it seemes there are almost 68Gb of data, but opening Disk4 it's empty Similar discussion for Disk 3 listed for 279Gb but if I open the Disk and "Calculate" I have 139 Gb Why that? Data for the Parity? How can I do? I would like to empty the two hdd and starting swithing to ZFS but if there are data I don't want to mess up my array
May 3, 20242 yr Community Expert As was mentioned an ‘empty’ disk still has space used due to the overhead of creating the directory structures for the empty file system.
May 3, 20242 yr Author Ok but......almost 70 Gb seems to be a little bit high as Number.... And what if I format the disk?
