This is generally true. If your drive loads a program that is a
commercial prog. or as you stated, the disk that came with your 1541,
than the alignment is probably ok. But if you start having problems
loading commercial software, than you most likely have an alignment
problem. It has been my experience as an CBM service center, that 
with the later drives (the ones with thee flip down handles), that 
they rarely get out of alignment. If you format a disk with an out-
of alignment drive, than that drive will load any programs that are
saved on that drive. But anything saved on an out of alignment drive,
will not load properly on an in-alignment drive. If you suspect that
your drive is out of alignment, the only sure and accurate way to check
this is with a digital alignment disk and a dual trace scope.
