overwritten data is possible, but wonder if I'd need
special hardware to do it. Does anyone know something
about this ?

Thank You.

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.
