Thanks for caring.
So more details.
I have my mac pro with the 4 bays full of HDDs. Bay 1 had the system drive with all my applications, etc.
I got a new SSD pcie card which I'm not using for my system drive.
It has 433GB available so its got plenty of wiggle room.
I still have in bay 1 the old start up disk with all the applications in it--including FCP. I've gone in there and renamed FCP to FCPOLD and the projects and events with old at the end. I really don't think that is the problem as it hasn't made any difference.
The main stuff I work off and the one giving me the errors (not to say others won't give me errors either) is the ones with events and projects in the drobo which I used form the old user.
The new user has a different name than the old user... maybe that is a problem though I don't see how.
I ran disk first aid and repaired permissions but nothing.
Yeah get rid of the dupes/olds etc. Also DROBO is not the best drive for editorial work and never has been (though some folks might argue that point). I'd suggest pulling that off the chain for starters while you figure out the specific issue, getting rid of any project and event duplicates and second users etc. Basically do some system maintenence and get things down to the basics.
