If you do decide to keep it make sure you do not use the hard drive in it. It could contain illegal stuff even if you do not see it. If there was ever anything bad like that on there ever the police might be able to find it. I would take it to the police and see if they find the owner. If they don't you get to keep it. But still get a new hard drive for it if you keep it after the police give it back. Then get rid of the original HD using a method of data distruction.
I recommend:
- 35 pass secure erase (use disk utility)
- Smash or scrape off the chips with screwdriver of the logic board on the bottom then trash the parts on different days at different locations (restaurants, parks and public restrooms)
- Take it apart and throw the platters around like frisbees on concrete or similar rough surface
- Throw the platters away on different days at different locations (restaurants, parks or public restrooms)
But do not just throw the platters out the window of your car as this is littering.
Overkill much?
