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.
