Either the OS software became corrupt and became unable to complete a startup or the drive itself developed a mechanical problem.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>The easiest way to determine which condition caused the problem is to attempt to do a "Clean Install" of OS-9 on the drive. You should use the same installation CD that you used before and start the installation as normal except that you should check each of the option buttons to find the "Clean Install" function. Once you find that option, select it and then continue with the installation procedure as you did previously.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>This will give you a valid operating system on the drive that you can boot to. You should be able to locate your original System Folder with the new name of "Previous System Folder" in the contents of the hard drive. Once you have verified that the new system is working properly, you can delete the Previous System Folder safely. Of course, you will have to consider reinstalling any third party software that you had in the old system onto the new one.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>If the installation CD does not find the drive you want to do the "Clean Install" onto, then you probably have a dead drive and will need to replace it and do all your installations over again onto a new drive.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>At least, you will have learned how to do a minor trouble-shoot procedure. At most, you will have a new drive to play with.</DIV></BODY></HTML>
