I have an EX5 with the external SCSI port. I have looked on several EX5 web sites to find drive compatibility. None of them list any compatible HARD DRIVES, just CD-ROMs and JAZZ and ZIPs. Does anyone know what type of EXTERNAL HARD DRIVE I should get to work well with my EX5? I don't need anything bigger than 2GB. I also don't want to spend an exceptional amount of money.
