Partitions 1 might be the Backup though!
I don't think you should of formated the new partition as NTFS, Linux doesn't like that, (NTFS that is). I wold of left it unformated. The reason it said read-only is b/c its a NTFS partition, means you cannot write anything to it, You'd have to recompile kernel then to add support. Thats why I wouldn't of formated it.
