Say you partition 2GB for / and 4GB for /alt... On day one, you receive 1GB in / and 3 GB in /alt, in day 2 you receive 3 GB in / and 2 GB in /alt, you screwed.. Obviously this is not a 'realistic' example, but the point it makes is very realistic. It's much easier to accomadate the data when it all sits on 'one' drive... -- Rob === _/_/_/_/_/ _/_/_/_/ _/_/ _/ _/_/_/_/_/ _/_/_/_/_/ _/ _/ _/ _/_/_/ _/ _/ _/ _/_/_/_/ _/ _/_/_/_/_/ _/_/_/_/ _/ _/ _/_/_/_/_/ _/ Innovative Data Services Serving South-Eastern Michigan Internet Service Provider / Hardware Sales / Consulting Services Voice: (810)855-0404 / Fax: (810)855-3268 / Web: http://www.id.net
