What partition table format are you using? I sure hope
it's not msdos. If it is your problem might be caused by
this. I once had similar problems. I was able to replace
the msdos table with a GPT table, and then use the
gparted 'rescue' command to recover without loosing
a single bit of data.

Cordially,
