Just before going to bed I printed out the partition table with fdisk, dd-ed /dev/zero onto the first partition of /dev/sda, then ran fdisk again: this seemed to make fdisk realise that it ought to create a Sun disk label. Then I recreated my original partition table by hand. The PROM doesn't object to the lack of disk label any more. However, I can't mount any of my partitions. Apparently Sun-disk-labelled partition tables work differently from whatever kind of partition table I had before. (I think the disc was previously used by old SCO Unix on x86; cfdisk seemed to think that one of the partitions was labelled for "GNU HURD", which was funny.) If my experience of Sun is anything to go by, Sun call the first sector "3" instead of 0 or 1 ... :-) This should be in the installation instructions somewhere. In the meantime, does anyone know if there is a simple relationship between the values displayed by fdisk for a Sun-disk-labelled partition table and the values displayed by fdisk for other kinds of partition table. (And how many kinds of incompatible partition table are there?) Edmund
