I don't claim to be worldly knowledgeable in every OS, but all the OS's *I* personally have worked with, that have implemented software raid, you are able to mirror all partitions - including Winders. Even NetBSD I believe can mirror the root partition with their RAID utility. Seemingly the point of mirroring is allow for the complete loss of one drive, requiring only a reboot at most to be back up and running in a degraded mode, until the drive can be replaced and the mirror re-established. It just struck me odd more than anything that it was different in FreeBSD - at least for now :) Stephen Hoover Dallas, Texas To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
