[subscribing to FreeBSD-scsi as I type this] `mt status` shows "variable" as the default, and I am not specifying a blocksize to dump. Below is an example of how I am doing this, and all other partitions use the same options. /sbin/dump -0 -a -n -u -f /dev/nsa0 / On a side note, what happened to the "raw" device nodes [/dev/*rsa*]? I'm guessing that the lack of "raw" nodes doesn't make a diff, as /dev/*sa* are all character-mode devices. Matthew Jacob wrote: > > [ moved to scsi, followup there ] > > Hard to say.
