Thx a lot. I have formatted the disk using Gparted, now I have no acces to the drive I can "see" it but not copy to it, do I need to "automount" it ? – user56560 Apr 25 '12 at 11:59

Well I never actually encountered such a problem but from my experience I'd just format the partition that I want to be used as data disc.

contact me when you do that. I might have more info
