You can, but you might strike this problem:  The disc checks out fine on
one drive, but reads badly on another.

So a check checks the disc on that drive, and you may wish to check it
reads fine when you use it on another PC.  Or you may be happy to forgo
re-checking it.

Some burning software already does checksum the burnt disc against the
master, immediately after burning the disc.  I think Brasero does that,
I'm sure others do, too.
