So, a client brought over a seagate external with a backup on it from his mac so it is not visible from my pc, (assuming its formatted for the mac) I was going to use it to copy files from his dead windows pc to it. I thought I could accomplish this by booting to my ubuntu machine and simply copying the files to it, but I get a permissions error, the drive is read only and my user "root" is greyed out with not way to change permissions. Would another mac have access? he claims he never password protected the drive.
