Hey, thanks for your reply!
I just copied my music folder which i used on Windows onto my Mybook HDD and connected it to my MBP. I don't see those red circles, it's just locked.
The folder was unlocked at first but this changed when iTunes started to organise my files. So i copied all the music to a new folder and imported it into iTunes. It works fine and without locking my new music folder. Unfortunatly, i cannot delete the former locked music folder which would save loads of space... (it asks my wether i want to delete, i press yes, it playes the trash sound, but it is still on my HDD)
I wonder how to set my drive to Mac OS Extended Journaled though. Never seen that option... :<
I want:
1. to delete this folder
2. I want OSX to work properly with my HDD (un/locking files still doesn't work)
3. iTunes not to lock my music folder so that the music management works decently.
I guess it might be the fault of WD but Apple should be able to fix that.
greetings
