Can copying files to an external hard drive remove system folders in Mac OS 9?
To answer your question, “Can copying files to an external hard drive remove system folders in Mac OS 9?” No. The X’d Desktop printer aliases mean that the OS 9 can’t find the original drivers. If you check the Chooser I think they’ll be missing. It sounds like you have MOVED the Extensions folder out of the “blessed” System Folder. In the future I recommend using an old copy of Retrospect to back up your work. Even though its unsupported, it works.
