HI Zuki,
You can use a cdr or cdrw although you won't be able to use the write part, only the read part, but whatever you may have or find will work. IT HAS TO BE SCSI!!!
You can also usa a zip drive. Iomega still sells the 250 SCSI zip drive. You can use both too if you want to. The older drives or ok even if they are slow because the transfer is pretty slow anyway.
Hope this don't add to the confusion
