Running OSX 10.4.1 on an eMac; suddenly my external drive (firewire) doesn't appear on the desktop or in the finder--but it IS in Disk Utility, which says it is mounted and does not need repair. Whenever I power it off, I get an error message about having to eject it first (which I can't do because I can't see/access it). But I need it to back up/move files, esp. w/a main HD of only 80G. Found an article that said I should run following AppleScript; did so twice, got below error twice. (Help. I'm NOT a techie--in fact, I mistyped my username.) Thanks.
