can't quit photoshop cs

[kathleen_crimm@adobeforums.com]

this question may belong on an apple forum, but i've always been pointed in the right direction here.

am a new user of both panther and pscs. was enjoying learning both, but have begun to receive message "unable to save ______ because of disk error". this seems to be happening to anything i go to savein photoshop. consequently can't restart unless i force quit, since it won't quit with the open files on the desktop.

believe there is some relationship to having installed knockout 2; it has given me trouble from the start. this is happening to both files i have and have not used knockout on, but started on 2 i had used knockout on.

any clues how to proceed?

thanks!

Well, for starters, since you started noticing with the installation of Knockout, move it out of your Plugins folder, Reset your Photoshop preferences <http://www.adobe.com/support/techdocs/6712.htm> and try again.

Run Disk Utility (preferably from a bootable optical drive disk) and any other hard drive repair utilities you may have (I recommend DiskWarrior and Cocktail) to check for hard drive damage and to repair permissions.
