Arrrrrg!

It would appear that I have written hundreds of bad image disks.  Sigh!  There 
are too many disks to read each one so I have been spot checking images from 
time to time.  While writing this months .cal files to the computer where I 
am analyzing data I discovered that it would not read the ends of the files.  
Looking at the image disks which have 80 images on each, I found that it 
started making errors at image 64.

I guess I never spot checked a file at the end of the directory.  I do now.

I think all these disks have been written with K3B.  It seems to make it's own 
decision about write speed regardless of what speed is set.  So at the end of 
the disk (outside, I think) where the disk moves faster, the write speed is 
too high.  xcdroast seems to fail at the other extreme, it decides to write 
too slow.  

There is nothing that can be done about the lost images, I think.  Fortunately 
all the processed data is well backed up.  Well, sort of, since I can't read 
TR-6.  Hopefully I can get a copy of it from one of the three places I have 
sent it.  Don't do anything yet as I have not exhausted attempts to read it.
