[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.
