If i had a 200 gigabyte hard drive and i filled it up with pictures, then deleted them all and filled it up with a new set of pictures, can the old ones still be found somewhere on the hard drive, and if so where is this extra memory we cant normally use????
@tommot2002,
No, they cannot be recovered. The memory they were stored in was over-written when you filled it up the second time.
@tommot2002,
It is the Operating System such as Windows that merely change the status of the file to be overwritten. The data is still there. You would need a low level erase to completely remove the data. There are firms that can recover data for you but they cost quite a lot. I don't it will be recoverable after a low level erase though.

Weeeeelllllllllll.......... technically you should be over-writing it seven times or more. There are methods for obtaining the data after a single over-write.
