I'm confused about disk space on my hard drive. The hard drive in question is simply used for storage and not for anything else (it is not the root filesystem). It is an ext3 drive.
I would like to know if I reclaim any disk space on this drive. It is a 500 GB drive. But, when I run "df -h" it does not show up as a 500GB drive. It shows up as a "459GB drive".
Here's the df command output:
$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sdb1 459G 409G 27G 94% /home
It shows available only "27GB". I thought it should show 50GB "Avail".
Is there a way to free up space on this drive? Is there a better tool to view the real details of this disk? Why does it show up as a 459GB disk when it's really a 500GB disk? Is there a way to free up space without deleting "data"?
Thank you for your time and assistance.
