SUMMARY
Sometimes I'm struggling with external SD-cards and USB drives which were not cleanly unmounted.
Under some circumstances Linux mounts them as read only and there is no visible feedback shown to the user.
Only a look into the kernel log shows what is really happening in background and that an fsck run is needed with admin rights.

EXPECTED RESULT
It would be a big improvement if Dolphin would show:
- If the device has buggy sectors. So if something like the following errors appear in the kernel log:
[ 4472.908058] blk_update_request: I/O error, dev sdc, sector 16576 op 0x1:(WRITE) flags 0x0 phys_seg 1 prio class 0
[ 4472.908059] Buffer I/O error on dev sdc1, logical block 8384, lost async page write
[ 4472.908062] sd 9:0:0:0: [sdc] tag#0 access beyond end of device
[ 4472.908063] blk_update_request: I/O error, dev sdc, sector 698050 op 0x1:(WRITE) flags 0x0 phys_seg 2 prio class 0
[ 4472.908065] Buffer I/O error on dev sdc1, logical block 689858, lost async page write
  Then Dolphin should inform the user and should offer the option to run fsck on that device or partition.
- If the following message appears in the kernel log:
  "Volume was not properly unmounted. Some data may be corrupt. Please run fsck."
  Then Dolphin should also offer the option to run fsck.
- If the device was mounted as read-only Dolphin should:
  a) Show the device icon with a lock
  b) Dolphin should show a message when mounting the device/partition that it was mounted read-only and why it was mounted
     read-only.
  c) Show a button to start fsck.
If fsck is run a dialog should be displayed which shows the progress and questions which may be asked by fsck.
