hi-

	we had this problem too.   Justin Gibbs helped us out.
you need to change a value on "mode page 8".  what you have to 
do is get the "scsi" program compiled and run the following command:

./scsi -e -f /dev/rsd0d -m 8 -P 3

and change WCE to "1".


I believe the "scsi" command is from FreeBSD.   However, it has been
ported to OpenBSD, so I just grabbed all the necessary pieces and 
pulled it over to NetBSD (it doesn't require any kernel changes).
get ftp://dworkin.wustl.edu/pub/scsi.tar.gz if you want my port of
the OpenBSD version of "scsi" (includes i386 binary).

Oh, I suggest reading the man page before running "scsi" just so
you understand what it is doing.
