Have you partitioned up those drives...? Having 40GB on one partition is rather/really wasting space. The smaller the partition, the less space wasted--it all relates to cluster size-the minimum size for any given block of data (file). Soo...if you have a 2kb cluster, then a file with say, 500 bytes will still occupy 2kb. With...32kb clusters, that same 500 bytes will ocupy 32kb. Thing is...larger cluster sizes are necessary for larger partitions...smaller partition sizes=smaller clusters. (do i make any sense...?)
Of course, if you store big files on a drive....then cluster size/space waste doesnt matter as much.
Also...the Win2k partition isn't ususally much over 5GB. OS, all MS stuff, and other system essentials--ie antivirus or something should go on the OS drive. However, since the total drive is only 9GB...you probably might as well make the whole thing for windows...unless you have other non-OS related essential programs...
I would make one drive a "data" kind of thing- downloads, mp3's, office work, etc etc etc
And have one as a "executables"--games, benchmarking, and whatever else you have.
SCSI=most reliable...too bad i can't afford it...DOH
