I am experiencing one more problem with my Ubuntu 12.04... I have an External HD (500GB) which is NTFS formatted. I connected this HD on my Ubuntu 12.04 and copied some files. When I connected the HD on a Windows 7 machine I could find the folders (the were visible) but I wasn't able to copy/cut/delete them. However when I opened the folders I could handle the material (mp3s) in them. Does anybody know how can I fix this? How can I fully access and modify folders copied from Ubuntu via a Windows machine? Thanks in advance!
