I am doing this successfully, with a 1.6GB IDE HDD, a 1.2GB SCSI HDD, a
Zip drive (parallel, but registers as SCSI) and an IDE CDROM.  My
/etc/fstab looks like this:

/dev/hda1       swap            swap        defaults             1   1
/dev/sda2       swap            swap        defaults             1   1
/dev/hda2       /               ext2        defaults             1   1
/dev/hda3       /home           ext2        defaults             1   1
/dev/sda1       /aux2           ext2        noauto,user          1   1
/dev/hda4	/aux1           ext2        defaults             1   1
/dev/sdb1       /zip            ext2        noauto,user          1   1
/dev/sdb4       /zfat           vfat        noauto,user,uid=1000 1   1
/dev/hdd	/cdrom		iso9660     noauto,user          1   1
/dev/fd0        /floppy         vfat        noauto,user,uid=1000 1   1
/dev/fd1	/legacy		vfat        noauto,user,uid=1000 1   1
none            /proc           proc        defaults             1   1

...as you can see, the SCSI HDD is /dev/sda, and the zip drive is
/dev/sdb.  This is a very nice arrangement, because it gives me the
ability to have IO intensive apps (multimedia) read from one drive and
write to the other, and the data never crosses paths.  Also, having the
spanned swap space is kind of nice, but I have noticed that my machine
hardly ever touches /dev/sda2.
