You can't make a read-only fileystem read-write with chmod. You need to change the mount options. This could be your problem. You need it to be mounted read-write to chmod the directories that are causing you trouble, but you can't mount it read-write. There are ways round this. I'm wondering if the drive isn't mounted and I'm also unsure of what "mounted" really means; I see the drive listed in a file browser, and can access some folders and files, but not others. So I tried a command I found on the linux. Bash returned the following statement: ntfs-3g Matt, thanks for the suggestion.

Let us know if you have any problems. Didn't work. But it did attempt to change the file permissions file by file thus the text flying past in the terminal for five minutes. My first chmod attempt returned a message that the external drive was read-only.
