There is an Aztec Monster CF->SCSI adapter but it's on sale on ebay once in a while from a seller in Japan. Its about $120. There are two kinds that he sell, you want the laptop version of it and it fits into the hard drive space in the laptop nicely. Many swear by it but some curse it.

The CF should be a 2GB in size, partitioned into 700mb partitions in each. The Partitions should not be bigger than 1GB. You could set it up as:

200GB for System to boot.

900GB for your apps.

900GB for your files.
