did you make a copy of the crucial parts of the media with dd or one of
its friends?

Could it be that either GPT entries are faulty or the disk is dying and
reports now a smaller size? Ok, a smaller size will result in a
different behaviour.

If you know the original layout, you should be able to read the GPT
tables and compare them with what they should be. If you have the copy,
just edit them with the values you want. When the values match, the
partitions suddenly appear. 

I know, this is real hard core.
