I think a panic is the best thing to do to prevent any weird things happening. What else should be done when the disk it once had mounted goes away? you have different problems already when that happends.. Perhaps someone has a nice light which can be shined on this? p.s. Do not mail as root! create a normal user id for that with normal privileges, the super user account should only be used for system maintenance and updates and not for regular things like mailing etc, it posses an unnecessary risk for you and your system(s). -- Kind regards, Remko Lodder ** remko@elvandar.org FreeBSD ** remko@FreeBSD.org /* Quis custodiet ipsos custodes */
