My setup is just a 160 Gig firewire drive I'm using as a backup for my server. I hate dealing with tapes, so this is a good solution for me. It's nothing near as complex as what you're describing. The regular Mac OS Extended filesystem seems to work just fine and suuports files up to 16 exabytes, I believe. ------------------------------ Mike Loiterman grantADLER Tel: 630-302-4944 Fax: 773-442-0992 Email: mike@ascendency.net PGP Key: 0xD1B9D18E
