I did this from 300GB (single partition) disk to a 1TB disk (same block
size) and it created a 300GB partition with start/end blocks and all
flags identical.
I might need to take a closer look but it seems to be fine.
It works as long as the new disk is at least as big as the old disk and
has the same logical block size.
