re-fdisk'ing a partition - permission denied?

[Josef Karthauser]

I'm trying to repartition the drive in my laptop - trashing the XP
partition to make space for a stable file system so I can test USB code.
It appears that something has changed though since I last attempted this
kind of thing and I just get errors now.

The drive looks like this:

    ******* Working on device /dev/ad0 *******
    parameters extracted from in-core disklabel are:
    cylinders=77520 heads=16 sectors/track=63 (1008 blks/cyl)

    Figures below won't work with BIOS for partitions not in cyl 1
    parameters to be used for BIOS calculations are:
    cylinders=77520 heads=16 sectors/track=63 (1008 blks/cyl)

    Media sector size is 512
    Warning: BIOS sector numbering starts with sector 1
    Information from DOS bootblock is:
    The data for partition 1 is:
    sysid 7 (0x07),(OS/2 HPFS, NTFS, QNX-2 (16 bit) or Advanced UNIX)
	start 63, size 8376417 (4090 Meg), flag 0
	    beg: cyl 0/ head 1/ sector 1;
	    end: cyl 553/ head 239/ sector 63
    The data for partition 2 is:
    sysid 165 (0xa5),(FreeBSD/NetBSD/386BSD)
	start 8385930, size 69754230 (34059 Meg), flag 80 (active)
	    beg: cyl 554/ head 150/ sector 1;
	    end: cyl 1023/ head 239/ sector 63
    The data for partition 3 is:
    <UNUSED>
    The data for partition 4 is:
    <UNUSED>
    In-Reply-To: <1062947334.436.12.camel at quark.avioc.org>

If I repartition the first partition either using sysinstall or fdisk
I get an error when the write occurs.

Is there a sysctl to switch now?  I'm not running in any kind of special secure
mode so I would expect it to work.  Did the symantics change with geom?
