Yet another problem from the Prons

I did a short search (it was a brief search, becuase .hack is about to come on) and I couldnt find anything about it, but I can't seem to modify the contents of my hard drives, they are standard hard drives, IDE I belive, built in, ya know. But It seems like now (I think I was able to a while back, but cant now) I cant make directories or put things on my HDD1 or HDA1 ya know, my drives. So I set their permissions ya know allowed read write execute for everyone, and deslected read only. I still cant modify thingsin the drive, anyone got any ideas?
