uda50

[Danny Braniss]

The ra's have a tendency to produce bad blocks, unfourtunately, some of them
happen to be in the inod block, or the swap area, so the badsec patch
does not work. One solution is to reformat the hole disk (UGH!), the other
is to run a stand alone program from DEC, to mark the block bad. The one I'm
working on, is to have the Unix driver do it. The MSCP manual explains(?) how
it's done, I even figured out how the actual replacement works, with some
help of Dec's technisian. Before I ruin 400 Mgb of data, does anybody in
netland done something similar? (I don't mean trashing the Uda50/ra's, which
I'm temped to do!).

I agree, we have implemented that policy, but it's almost as difficult now
to obtain ANY info (appart from nice pictures) on any hardware from dec, so
we stopped buying from dec altogether.
