Actually some flipflops can give hints as to the bit that it previously hold'd - i think.

This is what Gutmann talked about in his paper, that magnetic force microscopy could be used to recover data which had been overwritten once. However, as I pointed out already, this was applicable to technology which is now 20 years old, and no longer the case.

More up to date research, especially this paper written in 2008 finds that for modern hard drives, a single pass overwrite (of *any* kind) is sufficient to destroy all data on the disk, even when magnetic force microscopy is used.
