Description Valdo 2020-04-26 11:33:36 UTC

SUMMARY
Wrong calculation of disk partitions' capacity?

STEPS TO REPRODUCE
The "Hard disk" I'm mentioning is actually a disk partition.
Command 'df -k' lists a capacity of 294243128 blocks of 1K (that is, 280,6 GiB) for a given partition.

OBSERVED RESULT
Dolphin's "Devices" panel displays 286.1 GiB (wrong) for that partition.

Note: same issue (if confirmed to be an issue - in all cases, pretty misleading) observed with kdepartitionmanager, showing 286.10 GiB.
On the other hand, the Device properties (in Dolphin) show a capacity of 280,6 GiB (correct).

EXPECTED RESULT
According to me, Dolphin's "Devices" panel should display 280,6 GiB.

Note: the same expected result goes for kdepartitionmanager.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma:

ADDITIONAL INFORMATION

Sorry for mixing , (comma) and . (dot) in my report for the decimal separator. In French, a comma is used, in English it's a dot :)

Does the size shown in the Devices panel come from Solid?

Hello, 
it is still a thing in Plasma 6.5?

Comment 4 Valdo 2025-10-30 22:13:43 UTC

In Plasma 6.3.6 (I don't have a newer version at hand):
- In Dolphin, a device Properties show the right capacity (expressed in GiB). So I consider this part as being FIXED.
- In KDE Partitions Manager, the same device still shows a wrong value (greater than what I would expect).
Note: I'm now running Debian (compared to 5 years ago), but I don't think it makes any difference.
