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. ) -- <Insert your favourite quote here.> Erik Trulsson ertr1013@student.uu.se
