This has been a major problem for my school for a wile, and with no solution in site, here it goes. When a teacher computer at my school has its hard drive replaced, crashes often, or otherwise needs to be cleaned up, we will typically format the drive, and install Mac os 9 and all of the applications that we use by hand (like, I run the installer for each in every application). Now we are trying to use apple software restore as a fast way to have a fresh install of all of the applications that our teachers need. So, we make an image first for the labs of G3 AIO's that we have, since we wanted to bring the labs up to 9.2. Image is dumped to a firewire external drive, works fine for restore on our server, everything is fine. Now, we also have iMac tray loaders in our yearbook lab, and since they use different software, and we would like to matain one image for one particular type of machine, I make an image, and dump it to our server, which has worked before when I made an image of another lab of AIO's. Everything seems to going fine, I'm running all of the necessary scripts as the PDF directions say. I wanted to just see that everything is fine, so I started up ASR to see that it would restore. When I select that image, the box down at the bottom of the screen says "Invalid or missing checksum" or something to that effect. It will not let me restore. Now, if I do another image, it will give me the same message. Heres the major problem: it gives me that error message no mater what computer I make the image from, except AIO's (haven't tryed the desktop version, but I'm shure it's fine, since they use the same motherboard). Blue and Whites and iMacs (tray and slot loading) are what I have on campus but none of them want to make a good image. I know my middle school has used asr just fine on those types of machines... but the system admin doesn't know whats wrong ether. We have upgraded the firmware on these machines to the latest we have. I have no idea what could be wrong, you guys are my last hope here.
