Thanks Godfrey - that makes sense. Near the top of my to-do list is to a - prune and delete files from across my several drives, aiming to keep no more than 2 copies of stuff (one copy one a RAID-1 system); b - consolidate scattered files; and c - shut everything down and physically reconfigure my external drive space to better organize the mass of wiring (and make room for possible additions). In the process I will now be paying attention to position-in-the-chain issues. stan -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
