Örjan,

 Hmmm, now that is interesting. The only thing that was changed in the
handleing of primary partitions was a check to see if the partition ran
off the end of the disk and whether it has non-zero start and length
logical block addresses. Maybe M$ doing some kind of address rollover or
negitive addressing, not sure yet.
 Are you a coder? It would be very interresting if you could send a
tarballed dd of the first block of the first drive to the mailing list
so I can see which end is up.
 Heinz, do you have any objection to us carrying this out on the mailing
list. I just like the advantage that somebody might learn something
and someone may have a better idea.
 On 2.6.10, I've heard it has issues, but don't have any personel
experience with it. Just trying to put it off as long as possible
since it didn't make your partition go away 8~).
 In an earlier message I asked you if you had done an mkfs, well that
was in error. It should have been format. I sent out a correction, but
it never reached the list.
