Bug 446395

SUMMARY

I have KDE Plasma. Plasma has a removable device notifier. The "Automatically mount all removable media when attached " option is turned on.

When I put an SD card into the laptop's built-in reader, the card is mounted. But when I click "Safely remove" for that card, it is immediately mounted again! I have to use "sudo umount" to unmount it.

The laptop is ThinkPad P1Gen3. The issue does *not* seem to happen with an external card reader (attached via USB), nor with a USB flash drive. But it happens every time with the internal SD card reader.


STEPS TO REPRODUCE
1. In the KDE Settings under "removable devices" ensure that the "Automatically mount all removable media when attached " option is turned on.
2. Insert SD card into laptop.
3. List the files on the SD card to ensure it is mounted.
4. Click the device notifier icon and click "Safely remove" for the card.

OBSERVED RESULT

The card now appears in the notifier twice, one of the entries is greyed out. After I close and reopen the notifier the card is there only once. At all times, the card remains mounted and the "Safely remove" button is offered again.

EXPECTED RESULT

Card is unmounted. "Mount and Open" button is offered in the Device Notifier for the card
