[?] Copying audio from a Compact Flash Card (bit-by-bit) to a CD

  1. Hi,

    I'm trying to locate the manufacturer or supplier of a copying
    system, that does NOT use a PC, that will allow audio recordings made on
    a recorder that uses Compact Flash cards to be copied (bit-by-bit) onto
    a non-rewritable CD for archiving.

    We need to be able to produce completely accurate data images of the
    original recorded material, on a regular basis, possibly for evidential
    purposes, WITHOUT requiring a skilled operator familiar with a PC and
    suitable audio management software.

    Our ideal solution would be to purchase such a unit outright, if one
    exists. Our alternative approach is for us to source and obtain suitable
    items of equipment and then use them to build a stand-alone 'box' that
    has a CF reader and a CD burner. This 'box' would have to be fully
    'idiot-proof' and have minimal user controls - maybe just a single
    'COPY' button that initiates the copy process, and appropriate
    indicators to monitor progress.

    Does anyone in this NG know of such a unit, or have any constructive
    suggestions about how this requirement could be met?

    Many TIA,

    - Dave

    What you are looking for seems to be something like the "Digital Wallets" used to store photos from digital cameras that do not have
    swappable memory cards.

    After spending a little while with my friend Google this is what I've found:

    ALERATEC DIGITAL PHOTO COPY CRUISER PLUS - PART # 310102

    http://www.aleratec.com/diphcocrpl.html

    ALERATEC DIGITAL PHOTO COPY CRUISER - DIGITAL FLASH MEMORY TO CD-R/RW MEDIA COPIER

    http://www.aleratec.com/diphcocrdifl.html

    I have no idea if these are any good even real products.

    It's not clear from the web site if these will handle audio files.

    Further it is very unlikely that you will find a CF-Card bit copier as a commercial product.

    It's amazing the lengths some companies will go to, just so they don't have
    to hire competent staff.

    You appear to completely misunderstand the reason
    for the requirements.

    I know some guys who could surely design such a thing. It would likely used an
    'embedded PC'.

    I suspect your requirement is too exclusive for anyone to market such a
    product.

  6. I'd bet that this will be an (expensive, to be sure) niche
    product in a year or two as CF-based recorders replace
    tape for applications in/around the legal profession.

    OTOH, as memory becomes less expensive, it may be
    worth it to just keep the CF cards rather than transfering
    them. Some enterprising CF card maker could even make
    a kind with a one-time break-off tab that would prevent
    erasure/re-writing, etc.

    Maybe, but : "WITHOUT requiring a skilled operator familiar with a PC and
    suitable audio management software" and
    "This 'box' would have to be fully 'idiot-proof' and have minimal user
    controls"
    looks straight forward to me. An untrained monkey will be the operater.

    What's your interpretation?

    Something that is so simple and foolproof that nobody,
    no matter how smart or dumb can possibly diddle the
    data, so that the inegrity of the contents and the legal
    "chain of custody" is beond question by either side.

    You've been watching too many cop shows it seems. Copying digital audio
    recordings with ANY box, will do no such thing. It's *people* who verify
    chain of custody.

    No kidding, this is a "drag and drop" type of operation in Windows Explorer.
    Drag and drop the files from the CF drive letter to a spot on the hard
    drive. If you want them on CD-R, that's drag and drop as well under Windows
    XP. The only trick to Windows is you have to remember to use the little
    "safe to remove hardware" thing that's in the task bar before you yank the
    CF card out of the PC's card reader.

    Still, you write this whole procedure up as a Word Document, with screen
    captures showing what to do, print it out, and stick it up on the wall next
    to the PC. If your employees can't follow those instructions...

    I've seen units that claim to do what you want, but I'm guessing they'd
    still need too much user interaction to be used by "any untrained monkey".
    General consumer products which do this would at least need to know which
    way you want to transfer data (CF to HD or HD to CF) and would also want to
    know if you want to do a "copy" or a "move" operation since you may, or may
    not, want to keep the source data after it's copied to the other media.
    SD cards have a sliding switch on the side to do this, similar to the
    sliding plastic "switch" on an old 3.5" floppy disc, it's just a piece of
    plastic. The actual switch is in the floppy drive and in the SD card
    reader/writer.

  12. There are legally accepted ways of making digital copies
    so that everyone is satisfied that nothing was diddled.
    Exactly. And if you can make a certified black box that
    any court employee can run, you don't have the problem
    of sending media out to a 3rd party to be duplicated with
    all the hassle of keeping track, having an officer of the
    court, etc. etc. But perhaps the rules are different in
    your country.
     
  13. IS this the requirement in this case?
     
  14. Mr.T

    Mr.T Guest

    Which of course focus on who was involved, not which box.
    Yes, perhaps the "court employees" are worse than untrained monkeys in your
    country, then again they probably are here too.
    No, actually that's just the judges and politicians come to think of it. :)

    You have one. Get a CF adaptor for your PC.

    Plug in the CF card.

    Right-click the desired file(s) and select "Send To..." then choose "CD-R
    Drive D:" (or whatever).

    Open the dialogue (or drive) and click Files | Write to CD.

    Done. Bit for bit ( it is data files you are writing, not audio CDs).

    I think you'd at least need to train the monkey before he could manage that
    :)
