I was using ubuntu 11.04 on my Laptop. While installing it from a DVD, I have created a 10 GB NTFS partition at the beginning of the hard disk, as primary. All other partitions ( swap, a ext3, a ext4 and a FAT32 ) are created in as logical in the extended partition. All were working well in ubuntun11.04.
Now the system was upgraded to ubuntu 11.10 via internet and was sucessful. But unable to either create folder/files or to write to existing files in the said NTFS partiton. But files in the partition can read - means mounting done. Same is the case even if logged in as root also. Fortunately no such problem with other partitions including FAT Why it is so, please help.
