It shouldn't be necessary to have a CDRW drive in order to use the .toast image. If you have a copy of Toast, you can use Toast to mount the ".toast" disk image. It should mount on your desktop just like another hard drive or floppy disk. Once it's mounted, you can then use Disk Copy to create a disk image of that mounted volume. This Disk copy ".img" file will be quite similar to the ".toast" image file, except that it can be opened with Disk Copy instead of Toast.

Actually, you may not even have to do that. Once the image is mounted with Toast, simply drag the icon of image (a disk icon) onto your hard drive, and all the files on that image will be copied to your hard drive, where you can then use them.

Hope this helps....
