Ah, yes. You got hit by that one. I have a couple of times and almost mentioned it, but was unsure of how you were using the terminology so I didn't want to add any more to the issue just then. I don't know just why that happens sometimes -- someone else might be able to explain. Some fragment of left over data must confuse things. But using the dd as you mention above does seem to fix it and that step is indicated in the bsdlabel man page, although not in a very enlightening manner.

First I try to edit the slice with fdisk but when he need to write I've got Information from DOS bootblock is: 1: sysid 165 (0xa5),(FreeBSD/NetBSD/386BSD) start 63, size 156296322 (76316 Meg), flag 80 (active) beg: cyl 1/ head 1/ sector 1; end: cyl 512/ head 254/ sector 63 2: 3: 4: Should we write new partition table?

I wonder what exactly you mean by 'format'. We don't tend to use that word to mean making slices (fdisk), partitions (disklabel/bsdlabel) or file systems (newfs). Usually format refers to something done at the very low leval of the drive and is normally only done at the manufacturer nowdays. I expect you mean one or more of the others, but cannot say. But, anyway, that is what you need to do - in that order. fdisk, disk/abel/bsdlabel, newfs So, try and explain what you have done using these utilities if you have and if you haven't, then check them out and see if that helps. If you really did a "format" under XP, then I think you can just start over with fdisk, but I haven't tried that on a hard disk much less a firewire device.
