I have covered this subject once but it seems the subject is in the news again.
First of all if you answered that question yes. Then I am only going to say one thing (actually not) your being pretty stupid. Ever wonder why the US Government smashes hard-drives before they send older outdated models to the their government liquidation warehouses.
Seems people are still selling their old hard-drives on the Internet and people are still gleaning a significant amount of data from them. Take this friendly advise take a hammer to those old hard-drives have fun doing it and don’t try to make a quick buck unless you know what your doing to completely wipe the info.
