Then using undeletion tools, they can gain access to your private documents that you thought had been erased.

To wipe E:, for example, "cipher /w:e:" I regularly transfer sensitive documents to clients using a thumbdrive - and I make sure it gets wiped between clients so that there's no leakage of information from one client to another.

For me this is StompSoft's Digital File Shredder Pro (http://www.stompsoft.com/fileshredder.html) which has a option to clean free space on your hard drive and can be scheduled to occur when ever you want, which for me is usually on a weekly basis. As far as the USBdumper or similar app working on my USB drives whoever tries to do this is going to have to break my encryption first otherwise there will be nothing to see :) “Wiping unused space in a file system”
