Yes, data recovery is a whole big topic that could occupy (already has in

was once told that the best and most cited paper/s on the issue is/are
somewhere in the Web site of Gutmann <

more depth and point to the actual paper if necessary.
There is a lot of stuff that Peter has worked on over the years, I read
one of his papers earlier this year. It is an old paper, but interesting
all the same. He had been using electron microscopy to extract data from
hard drives, for example, and also goes into some detail as to how data
can be extracted from RAM even several hours after it was last powered down.
As usual, there are two sides to this - data recovery and security.
We may be a small country, but for some reason we have some really
switched on guys (like Gutman) doing great work here. It is easy to
assume that software originates in large countries like the US, but
ghost came from NZ, and for a while Firefox releases were named after NZ
towns or suburbs, when the project was managed by a NZer.
