I’ve seen some mention in forums recently about disk problems caused simply by installing Photoshop CS2 on a Mac running OS X. It seems that the installer somehow creates some files with illegal names, and the volume header for your disk becomes corrupted.
Apple’s Disk Utility can’t repair these files or the volume header, and some users are reporting that “the damage sooner or later escalates into profound stability and operational issues that cannot be fixed”, requiring a complete reinstall of your OS and applications. I can’t confirm if it really is that drastic, though.
Some inquisitive souls on the Macintoshian Achaia forum, MacFixIt, Radmind and Macintouch did some digging around, and discovered that the illegally named files were the Vietnamese translation of the legal files. Deleting these (in the Applications -> Adobe Photoshop CS2 -> Legal folder) removed the illegal filename warnings, and allowed the volume header to be repaired (after booting from an alternate start-up disk, of course).
If you’re not sure which of the Legal files is the Vietnamese one, just delete all the ones with character sets you don’t recognise. You should also delete the unnecessary files from the Applications -> Adobe Illustrator CS2 -> Legal folder if you own Illustrator, as they apparently have the same problem. These files are not necessary when using the software.
I haven’t seen any official Adobe fix – if you know of one, please post it in the comments below so I can link it up.
