I'd like to travel without carrying a notebook computer and copy the
image files from CF cards to a CD, preferable several CF cards to a
single CD. I'd then mail the CD home for safe keeping. Is there such a
thing as a CF-card-to-CD burner that does not required a separate
computer?

Since 1GB CF cards hold more than a CD.

I think you would be better own looking for a DVD writer instead since DVD media holds
~4.7GB.

Not acceptable to me -- having the only copy of my picture on one
rotating magnetic medium is *not* adequately safe.

All modern harddisks are ensconced in a metal box, and made from
magnetic materials can only be tweaked by a very strong field floating
micrometres from the surface. Indeed, as capacities have increased, so
has this natural "protection" from whatever external fields can make it
through the box.

I guess if you just mailed the disk alone attached to a post-card or
something. But who would do that? I've received delicate instruments,
expensive optics, and even HD's in boxes via courier's and the mail.

DVD's, CD's, are too small, too finicky, too silly. Buy a pair of
80GB+ laptop disks (I find desktops bulky, but are perfectly fine if
you can accept the size/weight/power consumption), enclosures for same
with CF ports and do the backup trick.

Forget CD's and even DVD's for image storage. A portable drive unit
with a 2.5 inch HDD, available from 20 to 80 gigabytes, with direct
record from the built-in card reader - CF, SD, etc. - and a 2-inch
full-colour screen to view your shots. USB connection to your computer
to download when you get back home.

I use one myself, a 40 GB model. Good for over 4,000 RAW images from my
300D, at 7 to 8 megabytes each. Cost less than one 4GB CF card.

While I would use this too (I actually use my digital music player, which
hosts my USB card reader), the OP wants to be able to mail the images
home... Depending on the kind of adventure, (and what the possibilities of
theft) I'd say this is a good thing to do.

They may be enclosed in a metal box, but that metal box is quite
often cast aluminum, which offers little in the way of protection
against DC magnetic fields -- just high frequency ones, where the
induced currents by the AC field tend to buck the incident fields.

And a Faraday cage is *not* a continuous shell (as are the drive
enclosures), but rather a set of conductors in parallel terminating in a
single conductor. And they are good against RFI, not DC magnetic
fields.

Certainly the bent platters would render it unreadable by
anything other than a data-recovery specialist -- and only if it was
never put in a drive and spun up with the warped platters -- whether it
was degaussed or not. And the fact that there was sufficient force to
bend the aluminum platters suggests that there was a significant
high-frequency component to the field -- probably at the onset, which
did most of the work. That would have been done in milliseconds, and
the (much less than) one minute was not necessary.

And how many are available in the field -- in whatever country
you happen to be shooting -- to ensure that the mailing is safe. I have
heard of parts of the world where the most available packing material is
fresh-popped popcorn -- if the local rodents don't eat into your package
to consume your packing material.

Too small compared to the bulk of an external disk drive, with
power supply? And consider the mass which you have to carry with you
until you are ready to entrust it to the mail system of whatever country
you are in, and the various other mail systems between the point of
mailing and the intended destination.

Or do you mean that the capacity is too low? I think that a 4.7
GB DVD would be a pretty good match for a 4GB full CF card.

Also -- how does the cost of the CF cards compare to that of disks
in enclosures? Given the bulk question, I would be tempted to stock up
on CF cards, and keep them all with me until I returned -- or mail each
as it got full, and hope that those at the other end would mail back to
you the CF cards after they were safely copied to at least two storage
media.

> too finicky, too silly.

Exactly what is silly about a DVD ROM?

As for finicky, I have had no trouble burning them on my unix
systems -- though I have heard of Windows systems requiring shutting
just about everything which is running to safely burn a CD-ROM or
DVD-ROM.

I have had mere 6GB laptop disks die from a short drop (about 18
inches. I have never had a problem with CF cards dropped from greater
heights.

And what do you intend to use to write the laptop disks, as the
original poster stated that he did *not* want to take a laptop along?

That'd work; though at that point a laptop with a burner in it is
looking rather more convenient.

You are right about magnetic coercivity (meadured in oerstads)

However, the mecahnical shock (G-Force) of COTS drives are the delimiting factor.

There ar speciality drives that can withstand greater shock and are designed for more
extreme mobile applications. However, you are not going to get them through standard
outlets.

I agree with everything you said except -- "...DC magnetic fields."

It is the AC magnetic fields one must worry about because it is the constant transitioning
of North to South magnetic poles the degausses.

Thank you!

AC magnetic fields, slowly decreasing in amplitude, are what is
needed to *totally* degauss something. But a strong DC field could set
all the disk surface to the same polarity, which means no transitions,
and thus no data -- which is sufficient to render the data
unrecoverable -- *if* you have a strong enough DC field.

AC is preferred for erasing most analog recording media (e.g.
audio tapes), simply because a DC remanent in the medium, and/or in the
heads, increases the noise level (hiss) underlying the desired signal.

For digital media, the only thing which really matters is the
transitions from one polarity to the other -- and exactly when they
occur, so DC erase is sufficient -- and is exactly what is done in
computer tape drives. The QIC-150 drives for the DC-600 tapes record 18
tracks, one at a time, shuttling the tape back and forth. But -- when
it records the first thing from the beginning of tape, it writes
immediately behind a full-width erase head with a DC field. This erases
at least part of all tracks on the first write, thus making data
recovery difficult.

Enjoy,
DoN.

Not so, IMHO. Outboard drives are generally considered to be the most
reliable backup system available, better than optical media. But,
probably more importantly, if it were me, I would burn at least two
copies of my data, just in case the international post loses my disk,
and to have backup in case a CD or DVD goes bad.

I'm sorry I disagree.

That might be so without a readback to make sure that the DVD
made a clean copy before flushing the CF card -- and ideally burning two
copies on different brands of DVDs just to be sure.

However -- I don't think that those reports include the results
of trusting the resulting backup to the mails for shipping back home, as
was desired by the original poster.

Strong magnetic fields, such as might be found in various
explosives detectors, X-rays, and the like, could degrade the
information on the disk.

And -- the shocks of typical mail handling systems, even in the
US, would vastly increase the chances that the disks would be partially
or completely unreadable once you got home to where they were.

I would go for two DVDs -- as mentioned above, of different
brands of media -- and ship *one* home, while keeping the other in my
luggage.

Amen!

Kanguru make several portable card to cd direct burners. Haven't tried
them but have been tempted to get on for my next trip...

As for the portable hard drive option... I agree, I don't want to erase
a card until I have 2 copies of my images. But it is all a mater of
personal preference.

The other nice thing with the cd burner is you can also give copies of
your images to friends you meet on you trip.

Validating the CD is of course an issue, but if you have tested the
device and the brand of Cd your using the risk should be minimal.. Some
of the higher Kanguru models suport video out so if you can view your
images if you can access a tv set with video in..

I think you face a greater risk going to those photo booths (like at
disney) where someone who doesn't know what they are doing takes your
card and makes a CD for you....

FWIW

What about looking for the cheapest laptop with a DVD burner? Then at
least you can see the pictures with reasonable clarity as well to judge
for sharpness, etc. You could swap out the hard drive for something
larger as well. One copy in the laptop, one copy in the mail, another
copy burnt on DVDRW's in your possession which you are incrementally
backing up. Plus you can use the laptop for other stuff as well.
