Scott, thanks for responding to my problem.  However I tried this
yesterdayand found that fsck reports that the *alternative* superblock is
bad when I
boot via ramdisc etc..  If it scans for a superblock it can't find one, on
both
wd1a or wd1b.

Funnily enough I can view & edit the /usr stuff from UnixFS but not the
rest.
Irrespective of all this, wd1a & wd1b won't mount when booting from
ramdisc.

I think I'm about ready to give up and dig out my 40 or so floppies unless
anyone has any other suggestions.

Thanks,

Ian
