Other possible solutions: Use flash ram cards and a journaling file system. (soft updates may work but you need to talk to someone that knows about them much better than I do.) Use a live cd for everything read only, and use a remote machine for everything that needs write access. Hard disks really need to be powered down instead of having their power yanked. you are asking for a hard crash if you pull power from a drive that is actively reading or writing. Having this as regular part of the drives duty is asking for trouble. > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org" -- Write in TERRY BAUM for Congress on March 2, 2004 http://www.terrybaum.com/
