+ is eg 5 to 10 Gig.  (Thus one cannot store a 4.7 Gig DVD .iso).

+ 4,294,963,200 on fdisk type  6 slice created & written by FreeBSD,
+ 4,294,963,712 on fdisk type 12 slice created & written by FreeBSD,
+ This is an (MS architectural?) limitation, not a BSD bug, as:
+ 4,294,959,616 on fdisk type 12 created by Win-XP, written by FreeBSD.
