Running M7i routers with hard disk only is strongly discouraged - and Juniper should never have been selling them in the first place. We have flash memory in all our M7i routers. Running M7i routers with hard disk only is *especially* discouraged since the first model of hard disk used by Juniper was a "laptop type" hard disk *not* suitable or 24x7 operation - and prone to failure after sufficient poweron hours. As far as I know Juniper has recognized this problem, and all newer M7i routers are sold with a hard disk type which *is* suitable for 24x7 operation (e.g. Fujitsu MHT2030AR).
