It seems that old partitions re-appear after a deleted slice is created again. I then installed FreeBSD 9.0 from that thumbdrive onto that USB disk using a MBR schema. Of course, this booted after editing /etc/fstab. My problem are still the re-appearin partitions. I would like to have a script which flattens a media and creates new partitions and puts a new file system on each partition. There are now two options I have. Looking at the source (would be the ideal one) or do a hack deleting partitions which might not exist. The original problem of a GPT device not booting would still be there. I will go back to my normal work now. Erich
