In any case Royce's explanation is probably still correct; what I did in that situation (i.e. unable to use 'format') was put the disk in another Ultra, 'dd' over the first few megabytes of the disk just to wipe out the existing label, and then try 'format' again after putting it back in the original machine w/Solaris boot CD etc. IIRC the absence of a recognizeable disk label was enough to let the Solaris 'format' put a new label of its own on the disk. I don't recall if a Solaris boot CD has 'dd' or something else included to otherwise wipe out the disk label -- maybe someone else knows an alternate trick, especially if you don't have a spare Ultra to work on the disk. If the disk you're hoping to re-install onto is still bootable(?) you may even be able to use it to destroy itself. :-) Cheers, sr. > -----Original Message----- > From: Royce Williams [mailto:royce@alaska.net] > Sent: Thursday, February 05, 2009 8:09 PM > To: Ansar Mohammed > Cc: freebsd-sparc64@freebsd.org > Subject: Re: installing Solaris back onto ultra after FreeBSD > > Ansar Mohammed wrote, on 2/5/2009 3:52 PM: > > For some reason when I try to reinstall Solaris on my Ultra, after > > installing FreeBSD, the install hangs when it tries to write to disk.
