I still haven't got around to partitioning the drive or anything so I'm glad you mentioned the block size. I need to try and remember that. It may detect it itself but may not. I'd rather fix it now than wish I did later on. I assume that setting is in the man page. Thanks for that tidbit. Now to remember it. :/ Dale :-) :-) P. s. It's garden time for folks around here. I been busy the past few days. Tractor and tiller too.
