    Default Password Cracker

    Is there an application for Suse, that can Crack a password on a Sans USB drive. I have lost the password, or didn't write it down, now I need to open this USB to see the encrypted drive contents. What are my choices, I really don't want to wipe the disk?

    I doubt this is an allowed subject on these forums. Any attempts to do illegal cracks are not to be discussed here.

    So it is my disk, why would this be not allowed? The government and Law Enforcement does it all the time, so why can't I run a crack program to find out my own lost password on my own **** equipment ......

    It may be your device, but how can we know? How do yo want to prove it without having the password?

    It will be easiest just to wipe and reformat the disk, I will lose some stuff, but it is not critical information, but I didn't want to lose it. Thanks for your input anyway.

    These forums have very strict rules. Even if it is your own device, the
    same advice would help someone googling for a method to do the same on a
    disk that is not his own. I did not make the rules, I don't know if I
    agree with them, but they are the rules. I'll stay this side of the
    border :-)

    Anyway, I don't have knowledge on the "black arts".

    There is knowledge that is included in the man pages included in the
    distribution, which means that it was verified by the openSUSE legal
    team. I guess we can safely talk about that.


    What kind of password is that?

    Hard disks have a hardware password, part of the "ATA Security Feature
    Set". If you display the "hdparm" man page and seek for exactly that
    phrase you will find it. In fact, that is about all I know about the
    feature.

    I'm guessing it is this kind of password your disk is using.

    To my knowledge, it is unbreakable. Of course, I strongly suspect that
    others can break it.

    I don't clearly know if it is a lock, or if it is full disk hardware
    encryption. If it is a lock, the manufacturer can bypass it. I guess.


    Once a friend accidentally bricked a disk this way, and I was unable to
    find a way to break it. Fortunately... Well, what he was doing was using
    a Windows software to "secure erase" the disk, and as part of the
    procedure it applied a password. The computer crashed and the disk was
    bricked. Fortunately, restarting the procedure succeeded, because it
    used the same hardcoded password.


    If you google the subject, you will find commercial software that claim
    to be able to crack or unset this password (from Windows). I don't know
    if it is true. It is also possible that the disk manufacturer has a
    service for this, and it is legal - at least in my country. Same as when
    you lose your house keys and call in a key specialist to open it for you.

    You should google for your brand of disk and password or similar string.

    It's not really a question of it not being allowed, it's (as hcvv said)
    about (a) us knowing that someone making a claim is looking for a legal
    way to accomplish this and owns the device - and that they're being
    truthful, and (b) not providing an environment where discussion of
    activities that are legally questionable (assuming the person asking the
    question *doesn't* own the device).

    While the possibility of the forums being held liable for helping someone
    illegally access protected information are small, it's not worth the risk
    to us, so we just don't allow discussions on cracking to be held on our
    forums. The same holds true for cracking WEP/WPA passwords as well,
    which people have asked for help here as well.
