In fact, it will do its own thing even if you give it geometry numbers. All you need to know is the number of blocks. Check on the man page for the most recent version of disklabel (with FBSD 4.xx) and it gives some info on how you can blast it with fdisk (and maybe dd if needed) and come with the number of blocks. Then, just make a whole slice with fdisk and chop it up in to partitions to suit with disklabel (unless you want to do something ugly like slice it up and give some to MessyWin or Linus - even then the geometry is only what the SCSI controller makes it to be) ////jerry > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-questions" in the body of the message > To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
