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.
