I have a fresh install (well, with package updates) of Linux Mint 16 (Maté) on a 3TB hard drive. I installed with the following partition table:
/dev/sda1: bios_grub 1MB /dev/sda2: / 8GB ext4 /dev/sda3: linux-swap 2GB swap
with the rest of the drive unpartitioned and unused.
Now that I have things working like I want them, I open up GParted and create a partition for the remaining space. However, after doing so, it lists the partition as having used 43.90GiB: (transcribed from GParted's GUI, with superfluous columns/rows removed).
Partition File System Size Used Unused /dev/sda4: ext4 2.72GiB 43.90 GiB 2.68TiB
I mount the drive and run
Filesystem Size Used Avail Use% Mounted on /dev/sda2 7.3G 4.2G 2.7G 61% / none 4.0K 0 4.0K 0% /sys/fs/cgroup udev 1.8G 12K 1.8G 1% /dev tmpfs 362M 1.2M 360M 1% /run none 5.0M 0 5.0M 0% /run/lock none 1.8G 76K 1.8G 1% /run/shm none 100M 44K 100M 1% /run/user /dev/sda4 2.7T 73M 2.6T 1% /media/storage
So that is correct. I know it's an empty partition - this is a brand new drive. Refreshing GParted: (again, transcribed from GParted with extra rows/columns removed)
Partition File System Mount Point Size Used Unused /dev/sda2 ext4 / 7.45 GiB 4.40 GiB 3.05 GiB /dev/sda4 ext4 /media/storage 2.72 GiB 43.90 GiB 2.68 TiB
So, does anyone have any ideas as to why GParted is showing incorrect information for that partition? You can see that it's correct for /dev/sda2.
