System Monitor showing wrong disk capaticy

I'm encountering an issue with the system monitor on my Arch Linux system. According to the system monitor, it shows that I have 1.8 TiB of total space, but in reality, I only have 1 TiB of space available.

Here is the output of lsblk for my disk:

[vitalik@Vitalik-PC ~]$ lsblk
NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINTS
nvme0n1     259:0    0 953.9G  0 disk 
├─nvme0n1p1 259:1    0   100M  0 part /boot/efi
├─nvme0n1p2 259:2    0    16G  0 part [SWAP]
└─nvme0n1p3 259:3    0 937.8G  0 part /

System Monitor info

Kernel: 6.8.1-arch1-1
KDE Plasma Version: 6.0.2

Could someone please help me understand why the system monitor is displaying incorrect information and how I can resolve this issue?

Thank you in advance for your assistance.

Re: System Monitor showing wrong disk capaticy

That number shows you total capacity of all installed disks. Not technically incorrect and I doubt that this particular widget is configurable, you can create your own diskspace pages that would only look at mounted disk space.

I understand that the number shown represents the total capacity of all installed disks. However, in my case, I have only one installed disk with a capacity of 1 TiB, as evidenced by the output of the parted and fdisk commands:

[vitalik@Vitalik-PC ~]$ sudo parted -l

Disk /dev/nvme0n1: 1024GB

Re: System Monitor showing wrong disk capaticy

Mine is off as well.  I have 33.5 TiB and it shows 61 TiB.  Doesn't cause any problems and not something I mind.  I was trying to google and figure why it was so off and stumbled upon this.  So I'm not actually asking for a fix or tying to have anyone help I just felt that it kind of confirms what Mr.Vitalik had said so now he knows he isn't alone.

Re: System Monitor showing wrong disk capaticy

Idk what what widgets shows there, but MrVitalik gets roughly double the size of the root partition, so it probably gets counted twice…

df -h # df -H will print SI units
