This one was driving me crazy. Sometimes the Zip Drive would appear in the "Selecting Partitions to Image" screen, and sometimes it wouldn't. I tried restarting True Image, even rebooting. And the answer was always the same: Sometimes. The ability to put multiple True Image Files on one cd is a nice feature that Drive Image does not have. But an intermittent problem like this is the worst kind. I had put 2 images on the cd, but could not put the third. Finally figured out what was happening. There is a timer built into the Iomega software that puts the drive to "sleep" after 3 or 5 minutes (I don't know where it is set). If you access the drive in DOS, Windows, or Linux, it automatically wakes up. But not for True Image. I don't know why that is, but if anyone else has this problem, this is a workaround. Just access the disk using any of the above Operating Systems before using True image.
