Hi David,

I thought that too, but found out to my irritation(!) that this doesn't
work if the disk geometry is different (I'm assuming this was the problem).
I ended up with a partition table that had the first three partitions
(though only the first was mountable).  The extended partition showed up
as corrupted. :(

As always, it's a good way to learn! I won't forget that in a hurry.

Cheers,

Ben
