I found a "workaround" though the solution to my problem was not an answer to the question, the title was hence revised.

Can I clear/reset the mounted volumes list manualy?

I have a problem and I suspect that it might be a symptom of a hardware issue though I am hoping I'm wrong.

If I connect an external drive or mount a disk image it shows up in finder and I can see using the "Disk Utility.app" and it shows up using:

diskutil list

When I finished working with the drive or image I eject it an move on with my day unit a later point when I connect the drive/image again. The problem is, I now have two mounted versions of the same drive. Trying to open "Disk Utility.app" does not work as it endlessly keeps "Loading disks". There is nothing under /Volumes (so no mountpoint) however

diskutil list

Shows the duplicate disks still being connected?

/dev/disk2 (external, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *2.0 TB     disk2
   1:                        EFI EFI                     209.7 MB   disk2s1
   2:                  Apple_HFS Backup2_GO              2.0 TB     disk2s2

/dev/disk5 (external, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *2.0 TB     disk5
   1:                        EFI EFI                     209.7 MB   disk5s1
   2:                  Apple_HFS Backup2_GO              2.0 TB     disk5s2

/dev/disk6 (external, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *2.0 TB     disk6
   1:                        EFI EFI                     209.7 MB   disk6s1
   2:                  Apple_HFS Backup2_GO              2.0 TB     disk6s2

These are all the one drive which is no longer connected at all. I cannot eject the drive from finder as it is not mounted, I cannot do anything using "Disk Utility.app" as it does not work in this state and I cannot remove the drives using diskutil

diskutil unmountDisk disk2
Unmount of all volumes on disk2 was successful

Though it really was not as all drive are still there and not unmounted at all.

What can I do here? A restart usually solves this however that gets to be really annoying quick.

I cannot open /dev in finder. I can see the content using the terminal though I am unable to remove the mountpoints, even using sudo.

Any suggestions regarding a solution or what might be causing this issue would be greatly appreciated.
