I have a microVAX II running ULTRIX V2.0-1 (a little old, I know) that will
not boot because of hard errors from the disk drive.  On power-up, the
critter passes self-test, and boots ULTRIX to the point where is checks the
disk.  At this point I get

Force Error Modifier set LBN 5733
ra0a: hard error sn5728
Force Error Modifier set LBN 5580
ra0a: hard error sn5568
Force Error Modifier set LBN 5580
ra0a: hard error sn5568

and the boot fails telling me 

ufs_mount: fs /dev/ra0g not cleaned -- please fsck

fsck does no good, because I get the same Force Error Modifier set business.

Is this disk drive dead, or is there something I can do to get it back (the
people that use the machine don't back it up very often, of course; sigh)?

Thanks in advance for any help!
