[Gptfdisk-general] verify disk should warn if gpt table ends before end of disk

[Martin C. <cas...@un...>]

Hi,

I transitioned to a new, bigger storage medium by simply dd(1)ing it.
When I tried to increase the last partition, it was not possible. No 
free space at the end was shown.

"verify disk" did not mention any problems around that.
I write this mail because I think it would be useful, if this condition 
would be mentioned.

Using the expert command e fixes this. 'v' could recommend that.

You can check that with the attached sparse disk image.
