	Hi,

	Slightly related, and something I only found relatively recently which
enabled me to compress virtual hard drives that contained windows images.

	Firstly, make sure that empty sectors on the disk are zeroed, which
sdelete.exe will achieve for you.
http://technet.microsoft.com/en-us/sysinternals/bb897443.aspx

	Then use whatever tool you like that ignores empty sectors, comfortable
in the knowledge that all (well, most of) the sectors which should be
empty have been zeroed. Nice!

	Best regards,
	-->Gar
