Seems some 15-20 years ago I heard about some companies (in the Orlando area) that could recover overwritten data on mag tapes up to around 10 generations back, if I recall correctly. There was also a scandal about that time due to the salvaging of a potload of mag tapes with sensitive data on them from weapon test telemetry, if memory serves me well. I suspect but do not know for sure that the same kind of techniques that were used on the mag tapes (something like a very high-resolution and oversampled read of the magnetic domains that was then used to reconstruct the contribution of each previous write up to whatever the resolution permitted) could be used on disks.... So do your overwrites a bunch of times, compadres. Nemo ISN is hosted by SecurityFocus.com --- To unsubscribe email isn-unsubscribeat_private
