h3. Recovery of Overwritten Hard Disk Data

Hi, a friend of mine just overwrote two months of her PhD thesis with
an older version. I know recovery of overwritten data is possible, but
wonder if I'd need special hardware to do it. Does anyone know
something about this ?
Thank You.

h3. Stolen laptop had PhD research

Thirty-fve minutes spent in Langley’s Willowbrook Shopping Centre cost
a Surrey woman much more than she had anticipated.
Langley RCMP say that while she was shopping from 1-1:35 p.m. last
Monday, someone broke into her vehicle and stole a number of items,
including a Mac iBook laptop containing the research she had compiled
as she worked towards her PhD.
“All that information was on that computer and she has no back-up
fle,” said Langley RCMP spokesman Cpl. Brenda Marshall.

Never has a man been so happy to see a computer full of data
spreadsheets.
Claudio De Sassi's world fell apart when a car containing almost three
years work towards his PhD was stolen two weeks ago.
De Sassi, a Canterbury University academic, could not hide his joy
yesterday as police reunited him with his stolen laptop and backpack.

A tiny television sits where a big screen used to, and a Christmas tree
stands with little underneath it...
Even worse than the gifts, the crooks stole a MacBook Pro laptop and a
LaCie hard drive.
The hard drive had … her dissertation and nearly seven years of
research for her doctoral degree she was set to fnish in a few weeks.
Osuna had everything backed up on a separate hard drive in a safe, but
burglars made off with that too.
"All I could think about is that all that time is gone, all that effort,
everything is gone," Osuna said.

She has a back-up for all but the last six months of research, but the

** 75% lost outside the workplace
* Very similar results from 2011 European report!
