    Adderad,

    If you don't have anything constructive to say and/or are not sure of what you're suggesting then please refrain from posting at all. People are looking for assistance, not guesswork and suppositions.

    I've also removed the links. Do NOT post links to questionable sites.

    dban.org is secure, not questionable.
    Also, it seemed that he wanted to make the files really unrecoverable, so i suggested him to remove the files he wanted, fill the harddrive with other files, then deleting them, recovering in that condition will only bring back the stuff he filled the HD with.

    And how is he supposed to know he's installed enough crap, to use your term, in the right places to override all of his private documents, etc.? What about saved passwords?

    Never thought of that, i never use password saving, and i do not save any history on my browser either.
    I can't go deep in this, i am young and not very experienced.
    Pardon me, you are superior xD.

    That's why you shouldn't post regarding things you don't know about. You're welcome to assist in areas that you are familiar with. Keep in mind people have different setups than you. And in the futre, leave the sarcasm at the door.

    Now let's allow this thread to get back on topic.

    Only Five snaps are allowed per post! You have two more coming for you! There is no big secret in taking snaps. Though each person has his/her fav., i have found "Greenshot" to be so easy, that if i can make it work, a well trained Orangutang can do it!:D:D Best wishes!

    You should be able to set it back to factory defaults. This will wipe out all of your information and put the computer back to how it was when you purchased it. As it boots, read the info there. It should tell you which key to strike to get that process started.

    LauraMJ: That won't do it, because the stuff he had before restore will be recoverable.

    Hmmm.....I'm not talking about a system restore. From what I understand, when you do a factory reset, everything is gone, it's basically reformatted and restored to "factory new" condition.

    Yes, it does.

    There are two ways I see to do this.

    1) Erase the C: drive with a utility program from a boot CD. Then do a factory restore from the boot prompt. This is the hardest for a novice.

    2) Do a factory restore from windows per the laptop instructions. Then clear the free space using CCleaner using only its "wipe free space" option. This writes a simple pattern over the data. I have tried it, and it only takes an hour or two to wipe about 90GB. This isn't Mil-spec erasing, but will stop most anyone except the CSI types.

    A better program for securely shredding deleted files is Eraser from sourceforge, but it is more complicated to set up and use, and is a lot slower. Not for a novice.

    --------------------------------------------------------------

    Edited: I did a factory restore on my laptop last month and recall there was a whole new user routine where I had to re-enter a new user name and other personal info to get restarted gain. If this is true for the OP's machine, then he might have to do a second factory restore after running ccleaner.

    Here's what I'd do (and have done in the past)
    Boot in to Safe Mode, log in using the built in system administrator account, Go to Control Panel / User Accounts, delete the personal user accounts, delete their data/files when given the option during deletion of user account.
    Reboot
    It should now login using the built in System Admin account in Windows normal mode.
    Download and install Eraser in readinesss for use.
    Got to C:\Documents and Settings and delete any left over user account folders {that are sometimes left over}
    Now Right click on your C drive and select Erase Unused Space. Click on 'Options' button and highlight option 4 - Pseudorandom data, click on the EDIT button, change the number of passes to 3. OK
    Ensure all 3 overwrite options are ticked on main window.
    Click OK to begin secure wipe of free disk space

    Once done, shut down, job done [​IMG]


    However you would be just as well to run the manufacturer's Factory Recovery procedure, this will wipe the drive clean and reload the factory image and return it to its 'out of box state'.
    How the procedure is done varies from manufacturer to manufacturer.. what make model laptop is it???
