Lately my external drives are giving me "could not save because of program error" messages. If I open a Photoshop file from the external drive and work on it then try to save it I'll get the error message. I can save to the desktop and then drag / drop / replace the file. Any ideas on how to fix this problem. Oh, Deja Vu "disabled" message this morning. I had purchased it yet claims the trial period is over. I know it messes with permissions when it backs up files. I don't know if this is connected to the problem or not.
Repair permissions with Applications -> Utilities -> Disk Utility -> selecting the hard disk and selecting First Aid, and clicking repair permissions.
After doing that, uninstall DeJa Vu and get Shirt Pocket Superduper. I find it is much better at backing up than anything else I've tried. If it experiences an error backing up, then the problem may be with one of the drives or the cables in question. It could be a directory issue which only Alsoft Disk Warrior can fix. Try to keep your hard drive more than 15% empty. That's an arbitrary amount that seems to keep Mac OS X happier.
Only clone your data from an account which has no active running applications. That will avoid errors when backing up.
