Actually, almost every time you log out of a FileVault-using user, Mac OS X asks you if you want to compact the encrypted image. If you do this, then the free space is removed from the image and the entire discussion above becomes FUD. Its only if you do NOT do this, *AND* if you mis-understand what a volume is (as mentioned in the first reply to this article) that you might be under the impression that "Erase Free Space..." in Disk Utility is not working as intended.

If you read the linked article, it states the compacting feature doesn't cleanly delete all the data. Some deleted files were found after the compacting had occured. It depends on where the data is in the file vault bands.

There seems to be ways around getting the compact feature to run if the mac is powered on too.

It does bring into question how secure file vault actually is. It may also affect other encrypted sparsebundles too.
