Bug ID: 487650
Summary: Partition Manager fails to read MS-DOS partition
tables
Classification: Applications
Product: partitionmanager
Version: 24.05.0
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: andr...@stikonas.eu
Reporter: a...@absolutelyfree.me
Target Milestone: ---
SUMMARY
I have a few old systems running old versions of Windows and MS-DOS, so I am
regularly interacting with disks with MS-DOS partition tables. I frequently
connect drives to my system via USB to copy files over to these drives. I never
had any problems with this until today, so something must have changed very
recently.
If I connect a disk to my system via USB (either a USB flash drive or a SATA
drive with a USB adapter) that has an MS-DOs partition table, and then click
refresh devices in Partition Manager, the drive is detected but an error
appears when that drive is selected which says "No valid partition table was
found on this device". If I choose to add a new partition table to this device
and select an MS-DOS partition table, the operation completes successfully but
after the devices refresh, the same error is displayed. If I choose to add a
new partition table and select GPT, everything works as expected. I have tried
this with multiple drives, with multiple adapters, and with different USB
ports, but I always get the same results. I also get the same results on both
the LTS kernel and the mainline kernel.
STEPS TO REPRODUCE
1. Connect a disk via USB that has a valid MS-DOS partition table.
2. Open Partition Manager and refresh devices.
3. Look at the device in the UI.
OBSERVED RESULT
You will see a "No valid partition table was found on this device" error.
EXPECTED RESULT
The drive should be able to be read.
