    Worrying Photocopier video

    Dunno if you're responsible for photocopiers at your school - if you are - you might want to watch this short clip - quite worrying I thought

    I worked in a copy shop when I was in sixth form and our Xerox machines had hard disks even back then, so I knew what to expect, but they hit absolute paydirt with the machines they picked. Excellent clip to hit the point home with your school Bursar!

    I believe many copiers have drives formatted as FAT or FAT32, so even if your supplier wasn't going to erase the disks (or wanted to charge an arm and a leg), you could sneakily pull the disk yourself and erase just the free space, which wouldn't upset any system files stored on the drive (such as software add-ons).

    So the DPA doesn't apply to the school? Interesting. Does that mean the school isn't registered as a Data Controller with the ICO, and is therefore holding all pupil and staff records illegally?

    Wow, ok i admit it, i didnt know!

    Why do they need a hard drive to store images though!? Have i missed something?

    Unfortunately a plain format does nothing to protect the data on that disk; you need to properly overwrite every sector at least a couple of times to be sure.

    Photocopies have had HDDs for > 10 years so I'm not sure why this is news all of a sudden?

    There are lots of things you can do to deal with this issue...

    1) Purchase the photocopier once the lease runs out.
    2) Remove the hard drive, run DBAN on it (if it's a standard drive) or degauss it and then put it back in the copier.
    3) Scan lots of stuff to fill the drive up. Blank pages maybe?
    4) Pay the manufacturer to wipe it for you.
    5) Arrange for your engineer to visit and reload the OS. This will sometimes format the HDD.
    6) Buy a HDD encryption unit for the copier (if available).

    Many new copiers have drive encryption as standard now (I think Xeroxes do) or alternatively have a self-wiping feature built-in; so this may not be a big deal.

    True, but a single pass with DBAN is enough. No one (apart from maybe the government) is going to be able to recover your data.

    Once, twice, three times a lady, depends how paranoid you are. The point is, a plain format just wipes the file allocation tables, it does nothing to stop recovery of the data on the disk.

    Ill be honest, I didnt know either. I thought the hard drive was there for storage if it was being used as network scanner, or if someone chose an option to save a copy, I didnt know it systematically stored them. I assume its to increase speed in some way?

    You're not alone! It's something I'd never given a thought to. We have a Konica Minolta engineer in this afternoon so I'll be having a little chat to establish which copiers have a HDD, what's on them and how we format them when they go!

    Didn't realise that they worked in such an inefficient way as to leave documents in memory after the job had finished! 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.

    The machines really should be deleting as they go along, or encrypting the data. Seems like a failure of the industry to me!

    Erasing the entire drive might annoy the leasing company of course.
    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."
