It has another issue with it also - what if clever criminals realise that this goldmine of data exists and starts targeting copy machines? It only takes a few minutes to remove a hard disk from a copier.
    Leaving the documents around is faster, helps a lot with debugging, and provides some limited evidence acquirement for purposes in the future. That said, it is mostly plain laziness IMO, and at the very least the leasing companies should be checking that machines are clean before sending them on to somewhere else. On the part of the manufacturers, $500 for a 'wiping and encryption unit' is just profiteering.

    From g4u - Harddisk Image Cloning for PCs :
    "Windows "onboard" solution:
    Aparently Windows XP comes with a tool to do some harddisk encryption that can also be used to write 0-bytes to the disk. To do so, run the following command: cipher /W:C: for drive C:. You will need to abort (Control+C) after the first round, else it will write random data after filling the disk nicely with 0-bytes."

    " /W Removes data from available unused disk space on the entire
    volume. If this option is chosen, all other options are ignored.
    The directory specified can be anywhere in a local volume. If it
    is a mount point or points to a directory in another volume, the
    data on that volume will be removed."
    Where did Windows come into it? And cipher can only operate on NTFS drives, which photocopiers are unlikely to be using.

    Anyone know what the "Forensic software easily found on the web" is? I'm imagining it is just an un-deleter of some sort, but curious.

    See the Free data recovery software for memory sticks thread for some examples!

    Especially now there is a video advertising the fact...

    Interesting, we are in the process of changing our photocopies, will raise it first thing tomorrow morning, also involve our security team, something I didn't know!

    Cheers for this.

    A Safegurading problem?

    How your office copier is spying on you in an unbelievable way – it has a hard disk on-board that stores every page copied – The Blogs at HowStuffWorks

    I know our school has copied student sensitive documents, and obviously a plethora of the usual things concerned with school administration.

    Now if this issue really is as serious as the report suggests there is potential for, do schools need to be taking appropriate actions?

    This is why we securely destroy all copiers by letting the staff use them If the service techs can no longer get them going then they are probably pretty safe

    Only the same actions as server hard drives... securely destroyed - a hammer and flame thrower should do the trick. It's what I've done

    I was just thinking the same, as we have an HP8550 and a Xerox 4500 printer, both have HDD's in.

    Might take them out sometime and see what they might be storing.
