and it does, I misread the output but have now reread it. It is 8e as you say.

 Try following the advise in the error message and

did so with this output:

I have started the LVM manager and there is a screenshot of what it finds at:

I only want to get the data off hda3 and I will then retire the drive.

Thanks for the reference to the tutorial, I'll read up on it.
