Subject: Floppy Disk Warning!!!

CompuPro did a number of tests and  concluded that DYSAN has
least wear and is about as good as any for error-free
performance.
       DYSAN buys their disks from Scotch (or else from same
source as Scotch) but I am told that they do more polishing and
quality checking.  I am also told that they take all disks from
same source, test them, and if they get any soft errors on one
side but not other they put the disk out as single-sided...
