There is a limit on FreeBSD slice size, but it is larger than that.

No, I suspect you just got caught out by different definitions of 'GB'
Segate (like all other harddisk manufacturers) uses the SI-prefixes
correctly and has 'G' mean one billion (1000,000,000).
So your disk is 500,000,000,000 bytes large (actually slightly more than
that.) This is about equal to 465*1024*1024*1024 or 465 of what FreeBSD (and
many other OSs) calls a 'GB'.

I.e. the 472 GB slice you tried to create is larger than the disk is.

( See http://en.wikipedia.org/wiki/Binary_prefix for much information
about the different meanings of 'GB' and resulting confusion. )
