I have an image of one HD from an iMac stored on my G4 server, and I've NetBooted another iMac and I would like to use the img file to clone the original iMac.

This is what I've tried so far: Drag the img file to the HD (just copies it), mount it and then drag it to the HD (the files didn't all copy), and open it and select all files and copy it (the desktop aliases don't transfer). What am I doing wrong, or not doing at all?

Mount the image and then write the image (using Disk Copy) to the volume you want. p

Sorry if I sound like a dope, but I'm just getting into Macs. Is the option to write the image in DiskCopy, under a particular menu? Also, is this in all version of Disk Copy ?

Yes to both. Use the Help if you're uncertain. p

Make sure that DiskCopy has enough Memory allocated to it in the Finder (Get Info...). When DiskCopy doesn't have enough memory, some volumes aren't copied correctly. This is less of a problem with versions 6.3.3 and later, but it could still happen. Another way to make a clone a drive is to use a RAM disk program such as AppDisk, while using virtual memory. Using a nice backup program like freeware VolumeSync, you can copy a drive to the AppDisk RAM disk. After it's done, save the RAM disk, and quit AppDisk. The AppDisk Save file can then be compressed with StuffIt and emailed or FTP'ed or whatever you like. Be sure to include a copy of AppDisk so that the drive can be retrieved using the reverse technique. Just be sure to set the Memory of AppDisk to be big enough to hold the files, and make sure the minimum and preferred settings match. It's also a good Idea to lock the program, so that the settings don't accidentally change. Changes to AppDisk's allocation of RAM are like changing a password to access the Save file.
