So what should I do > instead of the plain: > > root@rtfm:/home/mi (108) disklabel -e sd1 > disklabel: ioctl DIOCGDINFO: Invalid argument How about "disklabel -r -e sd1s1" (if fdisk partition 4 - if it is the only one - ends up as slice 1) for a start? If it is thought of by the system as damaged or unlabled I think the best one can do is writing a new one with "disklabel -r -w sd1s1 auto" and then edit the data. One will loose the previous data in it, though. > Where is disklabel stored on the disk, can it be saved on top of > my filesystem (which, I think, starts about 64Mb from the beginning It is on top of the filesystem (if the filesystem starts at offset 0 in the slice) but the filesystem doesn't really start at the offset 0 then but leaves 8 KByte alone for boot blocks, disklabel and the like. And from what I read the disklabel area is unwriteable with normal means so even a filesystem like the Dos one which actually will start at the offset given (as far as I know) shouldn't be able to damage it.
