Sysinstall nearly always says this, and undoubtedly sysinstall is 
nearly* always correct.  Ignore it and move on.

Manufacturers like to make their disks look bigger by using 1000 instead 
of 1024 when scaling Kb to Gb so:

    476 Gb * 1024 * 1024   = 499122176K bytes

    500 "Gb" * 1000 * 1000 = 500000000K bytes

which is near as dammit the same.


*In ten years of FreeBSD I have seen the warning many times, and seen 
people asking about the warning many, many, many times.  What I never 
remember seeing is any case where someone needed to do anything about 
that warning.  That doesn't prove anything (my memory is of unknown 
reliability), but you have my word that it's not *that* bad :-)
