I've just purchased a 4TB Western Digital Red hard disk for my Media Server. I want to understand why I've ended up losing so much space by formatting it as ext4 and then mounting it. I understand some will be lost for the drives own files but what I have lost seems a bit much.
Steps I have taken:
Formatted the Drive using
sudo mkfs.ext4 /dev/sde
Edited FS tab so it auto mounts at boot
UUID=3276bc13-20a5-4225-ad33-d8fecdd5216c /wd_red_1 ext4 defaults 0 0
Now when I run
df -h this is my output
/dev/sde 3.6T 89M 3.4T 1% /wd_red_1
Does it not seem a bit much that in total I have lost 700GB of space?
In comparison I've got a seagate 2TB HDD which I've been through the same process with and it's only taken 200GB (so I have 1.8TB usable). Have I done something wrong?
Server is running 18.04.3 LTS
