No, no. You don't sell the empeg. Just the drives sitting in there. I am selling my 10gb drive that came with my RioCar because the RioCar is just sitting there now.. why not make some $$ and let someone get a 10gb drive to upgrade with at a deal? Everyone wins!
Then, when I'm ready to use the RioCar I bought as backup (actually I am using it - my older Mk2 is sitting as the backup) I can buy a drive for it. By that time, drives will be bigger for the $.
I asked on the BBS a few weeks back if anyone had any 30gb drives sitting around. A few people contacted me and I bought one. So now, that person has some $$ to spend instead of a drive collecting dust. And I got a good deal. Not only that, but I didn't have to run the drive-builder software!
