I've a brand new hard drive. It's 3TB, and I've used Gparted to remove the NTFS partition and create a Ext4 partition. This screen shot was taken literally just after I created the partition and formatted it to Ext4.
Why must it have 2 megabytes unallocated?
Secondly, why is there 44Gb used? There's nothing on the hard drive other than a lost and found folder. I also changed the 'reserve space' to 0% see if it had anything to do with that. (It doesn't)
