Bug ID: 405617
Summary: Unable to unmount without removing
Product: plasmashell
Version: master
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Device Notifier
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: 1.0
SUMMARY
Since the internal SSD only has some GB, I also use an external (mechanical)
HDD with some TB for storage connected via USB-SATA adapter. This HDD shouldn't
be powered all the time, but only for the few minutes per day I need it.
My previous workflow:
1. click disk in Device Notifier to mount it (it automatically powered up)
2. copy stuff to archive/backup from SD to HDD
3. click "unmount" icon in Device Notifier to unmount it
4. wait a few seconds until mechanics settles
5. issue a "hdparm -y /dev/sdX" as root to power down
6. repeat with step 1 any time later
Newer versions of the Device Notifier aimed to improve the workflow by
automatically powering down. Unfortunately, there are regressions as described
below.
STEPS TO REPRODUCE
1. click on external disk in Device Notifier to mount it, then optionally use
it
2. click on unmount/safely remove icon in Device Notifier
3. external disk abruptly powers down
4. open Device Notifier again and try to mount the disk again
OBSERVED RESULT
1. The external disk is no longer listed in the Device Notifier. I have to
walk around the table to disconnect and reconnect the disk. Since SATA plugs
cannot be removed without some wiggling when pulling, I fear that I soon break
the SATA connector on the HDD, and never be able to access the disk again.
2. Power-down noise is different (and sounds unhealthy) compared to previous
workflow
EXPECTED RESULT
1. The device is still listed in the Device Notifier (because it is still
connected) to be able to mount it again.
2. The device is powered down in the same way the 'hdparm -y' call did,
ideally with a few seconds delay to settle down the mechanics.
