I am pretty sure that you are right. I have installed several distros and I
think that the partition table is in a confused state. Partition Magic
rejects the entire disk, claiming there is just one partition of type
'bad'. 

I have used sfdisk to adjust the (c,h,s) values to the correct values 
and I have used gparted to move the partitions apart so that they are 
no longer in any danger of being seen as overlapping, but this has not 
fixed the problem.

The partitions are used as follows:

hda1  Software to return the machine to the factory settings. If nothing
else works, I could try that.
hda2  Windows XP
hda3  Ubuntu 6.06
hdb4  extended partition including hda5 and hda6
hda5  Linux partition, misc. data 
hda6  Ubuntu swap partition. 

hda6 is before hda5 on the disk; I do not know why.

hdb1  A FAT32 partition for data I can access from Linux and Windows
hdb2  Debian Linux
hdb3  Extended partition, including hdb5
hdb4  An empty partition? I have no idea how that got there.
hdb5  Debian swap 


This is the current state of the discs:

 $ sfdisk -lV -uS

For this listing I'll assume that geometry.
