Can you run vgscan w/o the 60GB disk attached?  If so, that's very
odd...there may be some crud on the front of the disk that the LVM tools are
reading as metadata.

If you've updated the tools, you need to upgrade the kernel as well.  That's
normally why you'd get the invalid IOP protocol message.
