       I don't want to run Premier it's pretty old  way back 6.5 and it 
doesn't do a lot of what I want to do.  I was just curious to see if it 
would export or render the file. It does have sp2 and usb2.  I had 
forgotten about having to defrag windows so of course it hasn't been done.
         What I was referring to with the usb hard drive on the Ubuntu 
machine was that the drive is flagged as a media drive. I don't know how 
or why that came to be??  It is a storage drive on my machine.?   I had 
several crashed a couple months ago when We hyad an ice storm. Theremay 
be software damge.     I'll let you know what I find.     Thanks,
