When Disk Utility launches you’ll see the CD listed in the left-side of the Disk Utility window. Insert the CD into your Mac’s media drive and then launch Disk Utility (/Applications/Utilities). Is there any way to access that Windows partition of the disc from my Mac, to be able to transfer those files to a different medium? No matter what I do, I have only been able to transfer the Mac specific files onto the thumb drive. So, I thought I could try to transfer or “burn” the CD to a USB thumb drive on my Mac (which still has the optical drive). We looked online for the appropriate software but couldn’t find the right combination of software and drivers that worked. We have a software install CD that is compatible with Mac and Windows, however he has one of those new-fangled machines without an optical drive. I am trying to install the software for my Canon printer on to my husband’s Windows 7 PC. Schultz is attempting to reach across the great Mac/PC platform divide but has been thwarted.
