    I don't get why people talk about you need to re-write the data you have 7 times for it to be completely erased. Data on a harddisk is made by small magnets, which are either aligned "up or down" (not entirely true, but it is a general concept), corresponding to a 1 or 0. If you change a 1 to a 0, there's no way you'd be able to tell if it used to be a 1. Need a theoretical physics explanation of this if someone still claims that you need to overwrite data 6 or 7 times for it to be completely erased.

    I'm almost certain you are correct and when a part of the disk is overwritten, (as opposed to being 'deleted ' in the filesystem ), the previous data isn't recoverable.
    I seen that claimed several times but not once has anyone said how that could be physically possible.
    Probably just another scare story I think.

    Some really stupid people here.. -_-'

    Using warez isn't illegal. It is if you're using it for commercial purposes, even then police won't bother you but some other people.

    Jeez...

    Depends which country you're from...

    My whole computer is encrypted with Truecrypt. Without my password even the secret service couldn't take a look at my files. Encrypting everything decreases the performance a little, but you can hardly/not feel it. I haven't tried playing any new games though. But my computer is pretty good, so it should still work fine. In my country the music lobby is huge...

    Germany has the so called 'kostenpflichtige Abmahnung' (a warning letter with costs). Artist A tells lawyer B to pursue ppl who download his music. Lawyer B has a company with technology which saves IP addresses from file sharing users. He gets your name and address by going to the prosecutor who then goes to your provider. You get a letter. You can sign it, and you pay a few hundred bucks (maybe more). If they catch you again, you will have to pay huge fines because you signed it. You can also not sign it and risk getting prosecuted. Most of the time this doesn't happen, but it could, and then you're screwed. And even if it doesn't happen, they can send you another letter again a few years later ...
    btw: several thousands of warning letters get sent to ppl each month. All the money goes to the lawyer, of course...

    Of course, we also got search warrants. They take your computer, and they look at the files you got. This is the worst that can happen. That's why my computer is encrypted.
    Rapidshare gave ppl's names and addresses out here at least three times (I think there are three confirmed cases). Rapidshare is the most unreliable file hoster out there right now.


    Also in the UK they are trying to pass a law where the police are allowed to hack into your computer without a warrant/warning... but its not like the C.I.A don't do this everyday even though it is an invasion of privacy.

    In Windows operating system, deleting system is just unlinking it. All the files are still there until your operating system decides to overwrite it with new information.

    Either that or the freed disk space can be deliberately overwritten with a utility for doing so such as a low level format, or 'shredder' program.
    However some people have claimed that data can be recovered from areas of a disk that have been overwritten, and I can't see how that could be possible.

    Unless you live in a one horse town where the PD has nothing better to do, I would not worry about it. Besides most cops would look at you like " are you serious?". And if they did introduce a new bill or anything like it. We would just come up with a more creative way of sharing. They thought it would stop with Napster, but they only made it worse. Limewire is screwy, because the work with the USA Secret Service to stop sharing of personal files, but it's a matter of time until they shut them down as well. I'm very sure the way of warrez will be safe for awhile, but all these NON-POSTERS that keep reporting links is getting old. But it only slows the flow around the web.

    This is what wikipedia has to say on the matter:

     
    When data have been physically overwritten on a hard disk it is generally assumed that the previous data are no longer possible to recover. In 1996, Peter Gutmann, a respected computer scientist, presented a paper that suggested overwritten data could be recovered through the use of Scanning transmission electron microscopy.[8] In 2001, he presented another paper on a similar topic.[9] Substantial criticism has followed, primarily dealing with the lack of any concrete examples of significant amounts of overwritten data being recovered.[10][11] To guard against this type of data recovery, he and Colin Plumb designed the Gutmann method, which is used by several disk scrubbing software packages.

    Although Gutmann's theory may be correct, there's no practical evidence that overwritten data can be recovered. Moreover, there are good reasons to think that it cannot.



    So basically as you say after overwriting there's no evidence of a way to recover the data.

    However, the US Department of Defense (DOD) recommends overwriting a file 7 times for government files. I wonder why.
    I really wish I could find that forensic topic, because I'm positive that the author claimed that his lab is always "above the public" when it comes to software and that he should be able to recover overwritten data. Maybe he meant something else...
