RK05 Bad Blocks

I need some help in reading some RK05 packs. I have
17 RK05 packs and I have been able to read 14 without
a problem. Two others have 14 and 5 bad blocks, respectively.
The last has 1231 bad blocks. Is there any reasonably
easy and simple way to recover the bad blocks. These are
all RT-11 distributions prior to V5.03 of RT-11.

In particular, the one with 5 bad blocks is a copy of
another pack, so I was able to verify that the other
4797 blocks were the same. One down!

The ones with 14 blocks and 1231 blocks are for V3.0B
of RT-11, but they do seem to be a bit different. The
14 bad blocks are all in 5 OBJ files (for FORTRAN IV)
an I may be able to find a copy elsewhere. The 1231
bad blocks seem almost hopeless unless I can find the
same distribution and verify that the rest are OK.

Obviously there is no point in spending any money
since eventually someone will find a set of files for
V3.0B of RT-11. Any ideas. I have tried to read
each bad block a number of times - one at a time,
but no success.

I only have until Friday when I will be giving the RK05
drive and the borrowed RKV11D controller to Ethan
Dicks.

Sincerely yours,

Jerome Fine
