I had a Mac Powerbook G4 that suffered a series of kernel panics and finally died for reasons other than hard drive malfunction. That hard drive (HD320gB) was newish and in good shape, so it now resides in a Rosewill enclosure external to my desk top computer where the operating system is Ubuntu 12.

While the external (former Powerbook) drive boots easily in the Rosewill enclosure, I can't access my own files on that drive to move them. When I can, I plan to erase and reformat the external drive and use it for storage.

I learned that I can see the contents of my file folders using gksu nautilus, and I can open the files, but I can't move them off the drive.

The message I'm getting is tha I don't have permission, because Ubuntu says I'm not the owner. Rather "root" appears as the owner of this external drive. So I know I need to change the permissions in the properties window, but I'm not allowed that privilege.

EXTRA INFO: I ran sudo umount and sudo fdisk -l and got this:

pops-desktop@popsdesktop-SH67H3:~$ sudo umount /media/HD320gB
pops-desktop@popsdesktop-SH67H3:~$ sudo fdisk -l

Disk /dev/sdb doesn't contain a valid partition table

I Don't know why I'm seeing that last line of code. I'm pretty sure that hard drive was formatted as HFS+ in the Mac environment, and haven't read anything yet about how Linux deals with that.

One more thing - the (now externally enclosed [Rosewill case]) HDD is a Western Digital Scorpio Blue HD IDE Drive. I used a jumper shunt to make it a slave drive. Event at that, upon rebooting, it still shows as a root drive where I don't have owner privileges.

Can I get some help, please?
