See the thread: http://www.freebsd.org/cgi/getmsg.cgi?fetch=642921+0+/usr/local/www/db/text/2005/freebsd-questions/20050911.freebsd-questions I have definitely noticed a higher failure rate among drives that have been stored for a number of months. I can't give you any hard numbers, nor should you really believe them even if I did, because this depends on age of the drive, model, design, etc. If you are serious about data redundancy, why not simply set up RAID 1 volumes? They will provide much better redundancy, at a minimal extra cost, and with less work required on your part to maintain the mirrors. Sandy
