disk tuning

[Alexandre D.]

Hi guys,

I'm trying to determine the good commands to initialise a disk.
I would like to get the same result than with the sysinstall fdisk.

But If I use the handbook's command:

# dd if=/dev/zero of=/dev/ad2 bs=1k count=1
# fdisk -BI ad2
# disklabel -B -w -r ${disk}s1 auto

I do not get the same result. The slice is not defined exactly the same and
the geometry is also not the same.

How can I get exactly the same result with a command line thant with the
sysinstall's fdisk (A = Use Entire)?

Thanks

cheers

Alex
