John....the problem I see is that the ending cylinder of hda10
(Linux) and the beginning cylinder of hda6 (Fat32) are the
same cylinder. They are contesting over the ownership of
cylinder 935. So, either hda10 needs to end at cylinder 934
thus giving 935 to hda6 or hda6 needs to start at 936 thus
giving 935 hda10.
You can do this with Linux fdisk by deleting one of the
partitions and recreating it with the new/correct parameters.
The trouble is, how to decide which one to change? I don't
know that. So I suppose you could guess at one way, test it
and if it doesn't help or makes things worse, then try it the
other way. Hope this helps.
