[SOLVED] Disk has 50GB of nothing?

Hello guys,
I just installed a fresh arch installation again (after wiki instructions). I installed gnome-system-monitor and under 'data systems', it shows that my hdd has 983,4 GB (it's GiB), but only 933,4 GB (GiB too) are usable.

gdisk /dev/sda
GPT fdisk (gdisk) version 1.0.1

Partition table scan:
  MBR: protective
  BSD: not present
  APM: not present
  GPT: present

Found valid GPT with protective MBR; using GPT.

Command (? for help): p
Disk /dev/sda: 1953525168 sectors, 931.5 GiB
Logical sector size: 512 bytes
Disk identifier (GUID): 31BDDD30-E48A-4B62-B150-C712B331F343
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 1953525134
Partitions will be aligned on 2048-sector boundaries
Total free space is 2014 sectors (1007.0 KiB)

Number  Start (sector)    End (sector)  Size       Code  Name
   1            2048      1953525134   931.5 GiB   8300  Linux filesystem

gdisk says that my hdd has a size of 931,5 GiB, roughly 1TB. Why does gnome-system-monitor show me something else? (false?)

Thank you for disconfusing me.

Nothing really wrong with it.

Well, maybe you don't need a root reserve here (tune2fs -m 0 /dev/sda1)

And just to make sure the filesystem uses all of the partition space, you could resize2fs on it. Or tune2fs -l to see what the filesystem sees.

Re: [SOLVED] Disk has 50GB of nothing?

My actual question was why gnome-system-monitor shows 983 GiB of space, where's only 931 GiB?

Edit: Isn't important, thanks for keeping me calm .
