Used space on empty hard drive.

Post by earnestbunbury » Fri Jan 12, 2018 1:57 pm

I have a 1TB external hard drive. I formatted it to EXT4. When I click on the drive and look at the 'properties' section it shows a pie chart saying there's 50 Gigs of used space on it. Why isn't 100% blank? I can see some use for the file system or whatever, but what is taking up that space? Is it normal?

With the hard drive partition mounted, what is the result of the command:

Code: Select all

Usually 1% or so is reserved for meta-data.

By default a Mint ext4 format reserves 5% of the space for the root user. The idea is that an ordinary user should not be able to fill the drive and stall the OS. Obviously on a data drive the OS is not at risk, but that 5% still helps the block-allocation keep files as extents of continuous sectors, when you are writing new data. For a read-mostly 1TB ext4 volume I bring that 5% down to 0.1%...
sudo tune2fs -m 0.1 /dev/sdX1
...which is still 1GB reserved for root-only use.

Why EXT4? On a drive that size, and if you wanted to share the data on other computers, to avoid permissions being set on it, you could use FAT32 instead.

UPDATE: Thanks. I DID use FAT32. And you're right- all the permissions were right there to let me set them to me controlling everything (read, write, etc). I picked EXT4 because of my unbearable frustration at Microsoft Windows and vowing to just use Linux. EXT4 seemed more 'Linux-ey'. Thanks to all that answered. I will (again) donate.
