1. Put the disk in the drive and let it mount normally.

2. From a Terminal Window (yes, we are using commands on the command line):

Get mounted disk location, e.g. ” Name: /dev/disk1 ” (to be used in third command):

drutil status

Make a temporary mount point:

sudo mkdir /tmp/foo/

Mount the disk:

sudo mount_cd9660 /dev/disk1 /tmp/foo/

You now have access to the Windows files in the Finder.

When done, unmount the iso9660 portion:

sudo umount /tmp/foo/

Then unmount the rest of the disk as normal in Finder.

You can use this command to remove the temporary mount point, (or it should automatically get deleted upon reboot)

sudo rmdir /tmp/foo/
