I have 3 external drives mounted to MB. When the drives are off an exclamation mark is being displayed in front of these files. That's OK.
Now when I press insert (scanning for new files) ALL entries in the database from these external drives which are OFFLINE but marked in the overview as folders to scan, are being deleted or are not visible anymore. (Luckily I had a backup!!)
However, if I unmark these external drives in the overview all files are maintained in the database.
HELP!! This is a very strange behaviour.
