After deleting the drive, it gets rediscovered and I'm being asked how to use it....I add it to the linuxmce file structure as I had done so before. From there on its usually being mounted and accessible. Now its just kinda dead.
for example the link in /home/public/data/videos/ for the disk is !ST9320325AS (sda1) on moon39-G 
/mnt/device/88 is not accessbile.
doing ssh moon39 I can check /mnt/device/88 and see all my files...
unfortunately I cannot say whether or not this happened after the latest update, since I noticed the problem only later.
