You got the dd command wrong and made the file size change to something
it shouldn't be. I think you can use dd to truncate the file back to
what it should be (ie, exactly 1GB) but haven't had enough caffeine to
remember exactly how.
I think the underlying error is that block 672720 isn't going to be in
the first segment of the table --- you need to be zeroing something in
one of the other segments...
