Nick Brooker used DiskEssentials' DiskRX to fix reported errors on his disk. When he was done, the entire directory of his disk had been replaced by the directory for a CD-ROM disc he had called "AMUG CD 19.3." It turned out that he was using the utility Speedy CD. This apparently stores a copy of CD-ROM disc directories on your startup drive. Somehow, DiskRX found this directory and falsely assumed it was the directory for the hard drive itself! Other utilities that work like Speedy CD may have the same problem. Fortunately, DiskRX's Restore command got the original Directory back.
