So I have a snow imac that had 9.1 and I decided to put os x 10.3 on it. After updating the firmware (4.1.9) I got started installing 10.3.3 from some emac restore DVDs. Once the installer is halfway through base system part 2 it gives the same error in the installer log each time. Error: Could not read archive file. -pax: End of archive volume 1 reached- Error: Could not write file. -pax:WARNING! These patterns were not matched:- Some files for Essentials may not have been written correctly. Install Failed Error detected Name: NSGenericException Reason: Some files for Essentials may not have been written correctly (code 1) root: Installer Exception raised during posting of notification. Ignored. exception: Some files for Essentials may not have been written correctly (code 1) The installer then says you must restart. This happens at the same part each time. Now to me this says, "I can't read these files and cannot continue" The hd checked fine so to me I thought the DVD was bad. So now I tried to throw 10.2 on it from an older powerbook system restore dvd. Low and behold I get the same problem, the difference is though that it dosen't stop the installation on 10.2. It just keeps going and says the software was installed successfully, then when you try to run os x it won't boot and gives you a screen asking you to restart each time. So does anyone here have any suggestions? It's a 500mhz snow imac with 256mb of ram and a 26gb hd. I did run disk utility the hd checked out fine. I also selected it to format the hd when I first did the install wiping out os 9 so now I can't boot into anything.
