It isn't exactly a problem with DESGUI, but DESGUI does have a hand in it
(in this case). It is a "problem" with scandisk, but it isn't a bug, it's
a feature. More on this rather enigmatic statement below...

On your system, it seems the only thing writing to your drive while
scandisk is running is DESGUI. You are correct above in that if there is
a disk write, scandisk will start over. With a dot every 5 seconds or so
(on my machines, YMMV), scandisk will never get anywhere. The same is true
with defrag, I believe.

I don't think buffering the dots is a solution, because it whatever
interval DESGUI writes them, scandisk may still be running. The BEST
solution is to log to another drive from the one you are scanning. If
you only have a C: drive, this would have to be a floppy. The second best
would be to pause DESGUI, as scandisk is rather CPU intensive, you probably
won't get many keys done anyway, so no loss there.

This, of course, assumes you want the logs. If you don't, the solution
is even simpler. Turn it off. B-).
