Dear me, you couldn't have done it any worse if you'd tried.

I would read Roger's page on building drives over 60G. Install V2 Final Developer on it (not 2.10). Install one drive, as master, do the build manually. Remove it and install the second drive as master, do the build manually again.

Jumper the second drive as slave and install the drives on the cable and sled.

Install your music on the disc using emplode.

If you have more than about 60-70% fill of the disk, run the fids apps to do the sort, but READ THE FAQ FIRST.

Then you can consider doing things like upgrade the kernel to HiJack.
