will. You should never try running multiple copies on the same disk if
you want it to finish in a reasonable time. With one copy, you can do
long contiguous reads and writes, but if you have multiple copies
happening, the read and write head will be bouncing all over the disk.
And what does that have to do with the progress window issue?
