If it's folder shaped then it sounds like it's not a disk image.  I 
have 14 disk images mounted on my server, 10 are the normal disk 
ICONs, 1 is a generic CD-ROM ICON (it may be the original ICON, I 
don't recall) and three are Disk Copy ICONs  of a floppy on top of a 
generic document on top of a bigger floppy.

What happened when you tried Disk Copy.  Did you have problems 
creating or mounting the disk image?  Details, details, details...

When mounted on the desktop in OS 9, Disk Copy disk images look kind of 
like floppies. They have the exact same name as the CD, and if you can 
open and browse them just as if they were the CD...

Beyond that, that's about all you have. Roxio Toast and Aladdin ShrinkWrap 
are two other apps that do disk imaging (though Toast is really for 
burning), but they work on the same principals.

If an app makes a direct hardware request for the CD, you have to have the 
CD in. Period.

I guess that's the problem, as I can't get the Disk Copy method to work.

Could it be that the mounted image that appears on the desktop is a sort of
folder-shaped icon rather than a CD-shaped icon?
If so, any way to make a more "realistic" copy of the original CD?

You use Disk Copy, and it's pretty simple. The built in documentation 
explains it better than I ever could. Once the image is created, you'll 
lose approx. 650MB on your hard drive. You just double click the disk 
image, disk copy mounts it on the desk top like it would a real CD, and 
you're on your way.

Apps that just request some file on some volume will usually work with 
disk images; they say "i need file X that's stored on a volume called FOO.
"

Apps that make direct hardware requests usually do not, and this is the 
case with many games these days. They say "I need file X that's at IDE 1 
volume 1". By making direct hardware requests, they skirt around any disk 
image trickery.

You just have to use "Disk Copy" and just create a disk image from your CD.
Launch Disk Copy and it should be obvious. Usually, the disk image will work
for most applications. Some might not work, specially games that have some
kind of copy protection.

saving battery power with CD

2002-05-30 Thread csean 

A topic that comes up often, obviously.
Though I wanted to ask for specific advice on making a Disk Image of a CD
for programs that work only when their original CD is in the drive.
In my particular case I'm using a couple of dictionaries and encyclopedias
(most of which I run in Virtual PC/Win95), though I know others do something
similar for games, atlases, etc.

So, what exactly is the procedure for making said working CD Disk Image?
Does this work for any program, or are some designed NOT to work with a Disk
Image? 

Thanks for any help.
