Adobe's Vietnam Danger Do you use the $599 Adobe Photoshop CS2 ... or $499 Adobe Illustrator CS2 ...? Check the /Applications/Adobe Photoshop CS2/Legal.localized and /Applications/Adobe Illustrator CS2/Legal.localized folders for a file called Tiêng Viêt.html. If you find this file, delete it immediately. OS X can interpret the special characters as illegal file names, resulting in damage to your hard drive's directory that even Disk Utility's First Aid feature (/Applications/Utilities) can't fix.
The offending characters are ế and ệ, where the second accent indicates tone. Note also that if you navigate with the Finder the folder in question will be called "Legal".
I have both programs installed on my desktop and laptop. The desktop is OK. The laptop has some damage, and Disk Utility won't repair it. Unfortunately, the external hard drive to which I backed up yesterday (which took all afternoon) promptly went south and won't even mount.
UPDATE: The external drive mounted on my desktop Mac, but it's hosed beyond Disk Utility's ability to repair it. Time for a new backup drive.
LATER UPDATE: The Research Computing Center people were able to fix the laptop drive. As for the backup drive, I'm backing up the backup to my office machine (which has plenty of free space) so that I can erase the backup drive and, if all goes well, get that working and save myself a trip to Best Buy tonight.
