OK, so when fdisk reports fdisk: Invalid fdisk partition table found I use sd0a otherwise sd0s1a (of course if it is slice 1)? Or do I have to use the sd0s1 form only if the slice does not start at C/H/S = 0/0/1 ? So I have 3 possibilities (of course only for non root-disks): 1.) The whole disk is dedicated to FreeBSD and starting at C/H/S = 0/0/1 ? ==> I have to use sd0a. 2.) Like 1. but there is also a single slice entry pointing to that partition: ==> I can use sd0a and sd1s1a 3.) The partition starts somewhere else (e.g. C/H/S=0/1/1) and of course has a slice entry: ==> I must use sd1s1a. Partitions with C/H/S=0/0/1 are the "dangerously dedicated" partitions. I hope this is right; as I noted before, I couldn't follow the discussion from the start.
