Subject: SCSI Q: invalid primary partition table: no magic
Sender: owner-freebsd-questions@freebsd.org

Precedence: bulk

I just moved a SCSI disk that I was using for Windoze over to FreeBSD, didn't 
have any major problems in creating the FS but each time I mount it, 
"sd3: invalid primary partition table: no magic" is displayed on the console.

To create the disk I did:
        format
        zero label (dd)
        disklabel -rw sd3 auto ; disklabel -e sd3
        newfs sd3
 
Which is fairly close to section "2.3. Making Dedicated Mode Disks Using the 
Command Line" in Doug White's disk tutorial (except I didn't do the 
'disklabel | disklabel -R' part - what exactly is the intent of this since 
the old label was just zeroed ?).
 
Is the problem that I didn't initialise the FDISK slice table ? Right now it
contains garbage. I downloaded Greg Lemeys disk chapter from his ftp site and 
noticed that under 'doing it the hard way' he first does the FDISK stuff.
 
Thanks, Tony (please CC me on any e-mail replies)
