I just did this myself about a week ago. I remember getting the same message but I don't remember doing anything special. I think I just ignored it and told Fdisk to create a slice using the entire disk. Anyway, the numbers that Fdisk used were the like the ones on your HDD, 16383/16/63, not the ones the BIOS reported. Once I did the Fdisk and then disklabel, I mounted the drive and FBSD (using df -h) saw it as a 72G drive with 66G available. I wasn't sure if I was getting all the drive space I should be so I asked in -questions. Many responded saying that 72G was probably correct as many drive manufacturers count 1G as 1,000,000,000 (do I have the 0's right?) and not 1,024,000,000 or something like that. And then the difference between the 72G and only 66G available was because of the 8% free space that the filesystem reserves for fragmentation. Good Luck!
