How to mount the Windows partition of a hybrid DVD

A client of mine has an older Lenovo laptop with a defective DVD drive. He’s saving for a MacBook Air rather than spend money fixing it! I downloaded the installer for his new Fujitsu ScanSnap so he could get up and running right away. But the DVD has goodies that you can not download, so I offered to bring it back home and copy the installers to a USB stick. When I put the DVD in I only get the Mac partition. So here’s how I worked around it:

You need to have a mount point for the Windows partition, on the Mac one gets created in /Volumes when you mount something, we need to make one, so pop open your Terminal and do:

mkdir /Volumes/windows

This creates a directory named “windows”. You can name it whatever you want.

Now you need to find the device name of the DVD:

diskutil list

and, since the DVD is in the drive, you’ll see it come up as a device, and some partitions. In my case it was:

/dev/disk1
#: TYPE NAME SIZE IDENTIFIER
0: Apple_partition_scheme *3.3 GB disk1
1: Apple_partition_map 17.9 KB disk1s1
2: Apple_HFS ScanSnap 943.7 MB disk1s2

To mount the Windows side of the CD:

sudo mount -t cd9660 -r /dev/disk1 /Volumes/windows

sudo to prove we are an admin (SuperUser DO), and the mount command with options to mount 9660 format, the device and the path to mount it at.

It showed up as expected, and then I copied the installers I needed. You can try dismounting it in the Finder, but that will not work, you need to unmount it like this:

sudo umount /Volumes/windows

Note that it is umount not un-mount.

Then go and delete the directory, in the Finder or on the command line:

rmdir /Volumes/windows

After that, you can eject the CD normally, or if you tried from the Finder and can no longer see it, do it from the command line:

diskutil eject /dev/disk1

No I did not figure this all out on my own, I used an article from the codeweavers support wiki. Thanks!
