Implementing zeroing of deleted data

Description

To reclaim storage (e.g. shrink virual disk files) in virtual environments (e.g. VMware) the unused data blocks must be zeroed out. If data got deleted, a tool must be used to zero that data blocks. sdelete from Microsoft (formerly Sysinternals) can do this. But sdelete zeros the whole free space. A way faster method (and a clear benefit over sdelete) would be to zero only the blocks of deleted files.
AFAIK, there is no tool out there that can do this.

Yes, and the only way to do this will be to heuristically find deleted files and erase them. Eraser gets rid of deleted files, it doesn't find deleted files to erase. Furthermore it'll only be heuristic so not all space will be deleted and sometimes undeleted files may be deleted. It's not a risk I think is worth taking.
