Hello all, and Edgar in particular, It turns out that you were on the right track about Norton creating invisible files. A friend suggested that I search for files over a certain size, and sure enough, a 278 MB file showed up! It had been created by System Info, and when that program froze, it didn't get a chance to delete the file. I promptly trashed it, and everything's back to normal again. Thank you for your help! Despite the happy ending, this latest adventure with my hard drive got me thinking about backing up my files. I currently have only a few floppies with my documents and a couple of hard-to-replace applications backed up on them. What's my best option for archiving with my 2300c? External hard drive? Zip drive? Is there a CD burner available for my machine? Peter __________________________________ Do you Yahoo!? Yahoo!
