My advice is to not use dd unless you really need reblocking, are
working with tapes, etc. For the requirement above, this is probably
quicker and easier: truncate -s 500M file.img
No: truncate leaves holes. If you're creating a filesystem on a file,
it means that you can get ENOSPACE even if there would be space in the
file, but because the underlying file system ran out of space when
allocating a block to fill a hole.
How about this:
fallocate -l 500M file.img
?
