I created a sparse bundle, with a start size of 100 mb, then started
to copy files to it. It ran out of space before I was able to copy
everything to it.

I thought sparse bundles automatically expand in size. Do I need to
start over with a bigger start size?

Google is your friend:

http://en.wikipedia.org/wiki/Sparse_disk_image

When you create a sparse image, you're setting the _maximum_ size limit.
It will start smaller and expand as needed up to that limit. So, yes,
you need to start over with a bigger size, which is the _end_ size, not
the start size.

Thanks. I can see how the utility would want to know the maximum
size now that I have read your post. The installation process could
have been more clear though. Actually the three options (.dmg,
sparse image, and sparse bundle), could use some more complete
documentation - they are useful, but not obvious.
