    What do you guys know about data recovery? If I took a hard drive somewhere would they just read the drive bit by bit and recreate that data and recover it? Anything that has written over something that was previously there would still not be recoverable no matter what they did?
    Because I used a program that reads the entire disk but can't get data back once it has been overwritten. It's not worth paying through the nose for them to do the same thing but if they can do something I can't I might consider it. Anyone got any ideas?

    If it's been overwritten, no, it's gone, they can't get at it. You should use a program like Norton Ghost and make backups.

    u could take it to a professional Data Recovery place that opens the Drive to get the disks, but they cost alot.

    But even if they take out the platters they wont be able to get data that has already had something put over the top can they?

    you can get the data BUT its going to be unreadable, as i think it takes 3 overwrites before the data has been removed fully.
    u could ring up seagate or something see what they can do, but i think the dats gone.

    Um, no, one overwrite is all you need. Where'd you get the 3 idea from? One will do it. All your data is just a bunch of 1's and 0's, if one is switched it's toast. While it's true that deleting a file doesn't really remove it once you've written any data on that spot, it's irrevocably gone.

    Fraid not, places like the FBI and CIA (don't laugh at me) have specific ways of reading the magnetic field left behind from previous writes or something. There are programs out to secure erase your hard drive and they write random jumble to it a number of times before formatting. 3x is the minimum (close unholy ;)) and 9x is the FBI requirement for removing data on a hard drive before using it for something else.

    it wouldn't be possible to find something that has been changed unless u know how it was changed.
    Think about it.
    Example!!!
    If i put a Monitor in front of me, but i didn't tell you. then i removed it, u would never know it was there. (if i cleaned up the Dust that surround it.)

    It's unholy, it doesn't have to make sense :p
    Also that paper was from way back in 1996 so think about it, they have come up with better technologies since then ;)

    Data is data, if it's gone it's gone, technology isn't going to change that any time soon.

    Those special microscopes they use to read and recover the data have gotton much more sophisticated.

    haha, theres a limit, its like trying to solve a crime without any evidence... :p u can look but who says ur going to find, the chances are little, and because Computers store on magnetic disks, the chances of recovering those Slight Dints is near impossible is they ahve been over written.

    Exactly, the "better more advanced microscope" is only going to show you a clearer image of what you can't do. :)
