Yesterday I did what I have nightmares about ... I pulled a disk out while
the drive light was on.  Egad!  Panic!  thank god it was not irreplaceable,
but I thought that I would just fix it with disksalv and everything would
be wonderful.  I was wrong.
I reinserted the disk and to my suprise (and dismay) it crashed my Amiga
when it tried to validate the disk!

I managed to make a copy of the disk (using diskcopy) and tried the copy ...
Bango!  the copy crashed Amy too.  Third copy, same thing.

I have yet to try this on another machine, but has anyone else ever had this
happen?  What causes it?  I wouldn't think that the validator could
crash itself by reading a bad disk -  but since it can, it looks like we
have another thing to have nightmares about...
