KDE Plasma (latest as of today) on Manjaro.

Disk usage applet shows all four partitions, but reports 635,5 GB as total size. The thing is that the M2 SSD drive is 476 GB. Not critical but annoying .

The partitions are (according to lsblk)

1. Windows recovery 450 MB
2. EFI 200 MB
3. 83 GB Windows NTFS (dualboot system)
4. 150 GB shared FAT32 partition
5. 242 GB Linux/Manjaro

So there is a difference of 160 GB that is wrongly calculated showhow.

What sensors are there in your widget? By default it loads sensors for all mounted partitions, so if you have some external disk connected and mounted it will show as well.

I have Kubuntu 22.04 LTS on a macbook air 2013 .. and it too is showing a combined total disk space that is roughly twice what the actual disk size should be

459.9 GB instead of the actual ~256GB

this is the internal disk.. with no external devices connected at all
