Never mind...I repaired permissions again (three times in a row) and then restarted, zapping the PRAM five times. I can know trash away. Sorry to bother.

Rapairing permissions with Disk Utility doesn't really take care of all permissions issues. It just checks the listing for major applications and things that have been installed and repairs those. It doesn't do it for a bunch of data files put on external drives.
If you only use these drives for data storage as an accessory to your computer I would get info on a drive and select the "ignore ownership on this volume" feature.
Having said all that, I suspect there is something else going on. You say you have several drives. How are these all attached? Daisychained? In theory you can have a large number of FW drives daisychained. In reality I have seen posts where not all models really like having other drives plugged into them. Erratic behavior (and I am not convinced all your repairing permissions and zapping PRAM really did anything about the issue) might well be due to glitches in the chaining.

Yeah selecting "Ignore Ownership" was one of those things I initially tried. I was surprised when it had no effect.
They aren't daisy-chained per se. They are two drives in a single FW enclosure connected to the iMac's bus. I also urrently have a portable USB drive running with no such issue. Again, I've been having sporadic incidents like this since Lion so I'm guessing it's just part of that whole thing.
