      I have recently been having problems with my 1541 on several different
disks.  The problem is that when I write a file to a disk sometimes I generate
a write error 24 and the disk stops.  If at this point I do a directory I can
see everything up to the point where the new file was being written in the
directory.  After that point I get a head banging session and another error.
I have also seen this problem when deleting a improperly closed file (a star).
     My question is this, is this a problem of my 1541 getting overheated?
Is there anyway to recover these disks (about 6 in my files now).  I tried
tracing the directory blocks with a disk evaluator program.  I can find the
blocks before the problem and after but the block with the problem is now
all garbage.  Is there anyway to patch over the bad block so that I can
read the rest of the good directory blocks.  I don't understand the check-
summing required to change things in the directory block.  And finally is
there anyway to totally recover the lost directory block?
     Any help on this problem will be a great help.  At this point I'm triple
backing things up and I've still lost files.


                           Thanks in advance
