...which revision are you running?  -current?

For the record, I'm NOT able to reproduce these problems.  The proper
way to initialize a disklabel for the first time is to create a label
(you can do this by running disklabel sd1 > foo, editing foo, then
running disklabel -W sd1; disklabel -r -R sd1 foo).

...right... it's not letting you write over the label area for some
reason.  However, I had fixed this, I thought...

Please make sure you have arch/hp300/dev/sd.c revision:

Folks ... when reporting problems, it is _vitally_ important that you
include all relevant information, including revisions of source
files for relevant drivers, uname output, etc.  It's almost impossible
to determine what's actually going on otherwise.
