This makes no sense to me Alasdair.
This may be the error message but it defies explanation.
I still think there is something wrong with the lvm sine it's the one throwing 
the error and everything else seems normal.:
[root at fc11-64 ~]# pvs -v
    Scanning for physical volume names
  PV         VG         Fmt  Attr PSize  PFree  DevSize PV UUID

[root at fc11-64 ~]# pvscan

  Total: 2 [167.71 GB] / in use: 2 [167.71 GB] / in no VG: 0 [0   ]

Perhaps I just don't know how to interpret the output but it appears to be 
normal and I don't know what to do next.
I'm desperate to recover my old fc9 disk, any suggestions or step by step 
guides which might point out where I went wrong or what the actual problem 
might be?

Thank, Hugh
