Ubuntu File Permissions

[deafstep]

Hi,

I have a hard drive with an OS X system on it.

I've been attempting to gain permissions to backup files from the user folders.

I've tried chmod, chown and mounting it as root with no luck. The only things I've been able to change is my ability to view the entire file system.

Is there another way I can go about changing it from read-only?

Hi and Welcome !

Post the output of sudo fdisk -l and df -h commands here.

sudo fdisk -l
