First, my thanks to those who answered my inquiry and let me know I can expect 2 30 GB hard drives in the 60 GB RioCar I have ordered. Very quick and useful answers.

Tony, thank you for your reply and the FAQ reference that answers my question. I am most impressed with the RioCar.org site. I have spent hours reading the FAQ, forum posts and how to guides like the Rio Car Disk Upgrade Guide. I just missed the answer to my question. Perhaps I am suffering from information overload! Cheers...
