[comp.sys.next] broken floptical disks

I am having problems reading several floptical disks.
Several months back, I started getting ECC read errors
but was no sure what the cause was or how to repair the
disks. fsck could not find alternative bitmaps thus
was not any help. Now I find that two floptical disks
have corupt super blocks and can not be read at all.
Using the program disk and all the alternative super blocks
did not help - all the alternate blocks were unreadable by
disk.
Any ideas on how to read these disks?
I thought about doing a raw read of the flopticals and
doing some sort of string matching technique to get back
some of my private documents - seems a bit long winded
but may work!
