Dave,

Thanks for the response.

I went ahead and tried a few things. I trashed the Finder Preferences (plist) which did not appear to do anything, but I am not sure that it "took" right away. I had previously repaired permissions after completing the backup and went to update to OS 10.4.7. The disc image (which I had previously opened on the other drive) appeared to open, but failed. I trashed it and downloaded a new copy which I installed. On restart things were not quite what they should have been. I shut down and restarted with the option key, selecting the newly updated drive. When I finally got to it the Finder preference change appeared to have taken effect as the desktop icon sizes had reverted to the (default) large size as had the text size. I opened a Finder window and the icons appeared as they should. I reset the size of the desktop icons/text and things seem to be more or less normal. (I also repaired permissions after the OS update and after updating iTunes, iPhoto, iWeb and the iPod update.)

I had run Cocktail which is set to clear caches on the drive which I backed up immediately prior to the backup, but did not try doing so prior to trashing the Finder preferences and making the OS and software updates.

This is still troubling as I do not know what other "curves" SuperDuper! may have tossed in and I would prefer not to go through this every time I run a backup.

I guess I have a temporary solution, but not a longer term one. It will be a few days before I run another backup and I will have to see if the problem repeats itself.

Thanks
