Problems using Digikam with removable medias.

Hi team,
I have a problem using removable discs with Digikam 4.13.0 on Maxc OS X. 10 (Yosemite).
In the Preferences I set the place of the Digikam Data Base on the hard disk of my computer (Screenshot  01).
Then I added as Local Collection  an Album located on my computer in the Folder "Pictures " and called "Photos à Classer "
Then I added a new collection (called Photothèque 01) located on a removable (external) hard disc. At this moment appeared the message shown in the screenshot 02 (very hard to understand the meaning ???)
I clicked OK twice to close the Collections window of the Preferences.
All the Album of the removable media was imported very well.(Screenshot 03)
Then I quit Digikam and disconnect the removable disc
Now when I re-open Digikam :

• with the external disc disconnected :
•  The Album " Photothèque 01" of the removable média doesn't appear (Screenshot-04) and in the Preferences I can see that the Collection "Photothèque" has moved in the Local Collection.(Screenshot 04)
  
• if I connect at this moment the external disc the the Album "Photothèque-01 doesn't mount".
• with the external disc connected, the catalog appears quickly but I must wait minutes to obtain the thumbnails ???

I don't know if something is wrong in my settings or if it's an issue of the program.
Thanks for the help.
Chears.
Philippe
