ProSel's Mr.FixIt will test the disk and write a file to the disk that includes
all the bad blocks. You can not do anything with that file but as long as it is
on the disk it will keep ProDOS from trying to use those bad blocks for any
other file.

I hav ealso use Big Bad Block Buncher but have had some problems with it on
volumes larger than 5.25 disks. When the block that is bad is past the first
256 it would mark the wrong block as being bad. That may have been due to an
early version. ProSel has always marked the correct block for me besides being
able to read the bad block to try to recover anything from it.
