I have a 64 bit version of Ubuntu 12.10 (Quantal Quertzel) installed running on a ACER P6T SE motherboard. This is installed on the primary hard drive (dev/sda) and I have two other drives, one internal drive and one external drive. All are mounted.
Since installation I have only been able to access the secondary internal drive (dev/sdb5) for read only when logged in as administrator. I can copy to it from a /home folder but cannot save directly to it. I have tried to change the permissions through Properties/Permissions. This states that the Owner is 'root' but all the options are greyed out. Very frustrating.
Can anyone suggest a way of changing the properties so I can access it fully.
