Moved to the FAQ section, as suggested.

A few things that should be made clear with regard to a drive upgrade on the Central:

- If I recall correctly, the Linux kernel that's used for the Central will only support drives up to 127 gigabytes or so. And there is no upgrade kernel to fix this issue. So a 120-gig drive is approximately the upper limit.

- You can only put one hard disk into the Central. And there's no "easy" way to copy the songs from an old hard disk to a newer one. It can be done, but it involves some trickery and some knowledge of Linux.

- The original CD that came with your Central is not the latest software. It will work, but there is a slightly newer version that you can download from www.rioaudio.com if you like.
