If you're using the bundled "tools" disk, and you want to wipe it, and
format and mount it as a FreeBSD partition, you need first to 

scsiformat -w /dev/sd1

This, among other things, clears the "ro" (read only) software-set
attribute that will prevent you from writing to this disk, even if you
msdos mount it.  There is a linux tool (consult the FreeBSD SCSI mailing
list archives for info) that permits you to reset this attribute, but
I had no use for the tools disk and simply used the above low-level
formating command.

Best regards
