I need to pull about 13GB worth of data off my Ubuntu 16.04 box. I'm running xfce via Recovery mode. When I plug in my usb drive it mounts as read-only. So I do:

$ df -h ... /dev/sdb3 ... /media/user/backup_drive $ sudo umount /dev/sdb3 $ sudo mount -o rw,users,umask=000 /dev/sdb3 /media/user

These commands succeed. If I cd into /media/user I can see the files on the drive. But if I try to modify the file system in any way I get a permissions denied error. For example:

$ cd /media/user $ touch newfile touch: cannot touch 'newfile': Read-only file system $ sudo touch newfile touch: cannot touch 'newfile': Read-only file system

If from the xfce desktop I right-click on the volume icon and select Properties I see this:

Owner: 99 Access: Read & Write Group: 99 Access: Read & Write Others: Read only

Is it the "Others" permissions that's causing me grief? Any suggestions would be much appreciated.
