format disk in bsd

2006-01-05 Thread Nguyen Danh Hieu
Hi everybody
I have about 20Gb unused space and  40Gb of  NTFS on my HDD an I want to
change them to ufs . But everytime when I tried with cfdisk-linux   or
sysinstall = configure = fdisk (as root )  it is said that I am not
allowed to write disk table (or something like disk read only )  But I am
root , why did it happen? someone show me solution plz?
Thank you.

Are you booting FreeBSD from a 3rd partition on that same disk, and 
then trying to run these tools? I don't believe that is allowed. You 
need to boot from CD or floppy to do formatting and partitioning on 
the same drive that FreeBSD normally boots from.

There was a discussion about this the other day.  Someone reminded us
all that, by design, you can't change the slices and partitions on the
system disk.  You could do it by booting from Freesbie, or I believe
there is a flag you can turn off in single-user mode.  Check the
mailing-list archives for the last couple of months.
