  Like some of the others, I'm puzzled, which might just be my ignorance
showing.  Here's your partition table from an earlier post (I've tightened
up the spacing to improve visibility:

  It doesn't look to me like it encompasses hda3, which *precedes* it, if
I'm not mistaken.  That's the first thing that seems odd to me, that you
seem to have chopped off both the back *and* the front of your original
windows partition.  It looks to me like you started out with the original
windows partition, reduced it, then made the rest of the disk an extended 
primary partition (which would normally have been) divided into several 
logical partitions.  However, you tried to designate at least two of those 
logical partitions as primary, which in my inexperienced eyes breaks the 
logic of the system.  I'm wondering if the primary between 0 and 433754 is 
DiskDrake's way of avoiding the contradition of making a *part* of an 
extended primary a primary partition itself, by taking a chunk out of the
windows partition and thus staying out of the 9622935 to 39070079 extended
partition which I wouldn't think could *contain* a primary.  But then you
designated *another* of the contained partitions as primary, and apparently
this time DiskDrake said, "OOOkay, if that's what you want."  But I'm not
surprised RedHat wouldn't swallow it.

>Why is Mandrake able to work on such a partition table?

  Good question.  Like Civeleme said, it must be pretty damned robust.

  "All" you did, it appears to me, was ask it to make primary partitions
out of partitions which were themselves part of an extended primary
partition, which in my admittedly limited understanding is a bad thing
to do.

  It would make sense to try that, at least according to my quite possibly
mistaken understanding of the logic of partitioning.  However, RedHat has
several times barfed on my Mandrake partitions, and I'm pretty sure I had
had an hda1 primary at /, hda2 primary swap, hda3 primary at /home, and a
primary extended into logical partitions hda5 at /usr and hda6 at /var (if
I remember correctly).  I wouldn't have thought that would be a problem,
but it said each time that it couldn't read the partition table.  I've been
attributing it to the fact that the Mandrake partitions were ReiserFS, but
I don't know.  So you might still have to wipe.  Of course, my "analysis"
is probably full of holes, since I don't know much about partitioning
except by trying to logic it out.
