Does anyone know the answer to this question: Is it possible to
transfer jpg files from a hard disk to compact flash memory via the
various image reader/writers?

TIA

You an upload jpg files, or any other kind of file, to a memory card. It is
a handy way to carry data between computers that aren't networked. But is
likely that a camera won't recognize a jpg file if it has been changed in
any way or came from a different camera.

Marvin,


Thanks for the quick response. My plan is to work with either a Canon
PowerShot Pro 1 or Digital Rebel as the source of the pictures. If
the pictures are downloaded to my hard drive I might want to take a
sub set on another chip over to a Sandisk Digital photo viewer to view
on the TV or Plasma screen. Does this sound doable?

Thanks,

That should work if the Sandisk device can read a compact flash card. I've
not done it with that particular device.

I use my SM and CF cards in the camera and also to move files from my
desktop to laptop, to other folks computers ... from images to
virus scanners, driver updates etc (especially when building systems
or fixing boxes).

my multi-card reader works great (Lexar) , same for the PNY SM
and makes sneakernet fairly easy

My nikon doesn't seem to care, it writes images to a sub folder and
pretty much ignores anything else

your mileage might differ

I haven't uploaded images to the card to see if the nikon can
recognize them, not something I considered.

I frequently use SM for this purpose and have never had a problem. I
carry the drivers for my card reader (as well as drivers for other
devices) on a tiny business card cd so that if I encounter a computer
that needs them I can load up quickly and get to work.

Hello,

you seem to have some knowledge of CF cards.

I have a problem with a CF card where the directory structure has been
partially overwritten by the save of the last file (bigger than the
free space) inside my Nikon Cooplix 2000 digital camera.

I wish to try to recover the photographs stored on the card. Now I can
still see the top directory level, but not below (where the pictures
are stored).

Would anyone have a link or an idea as on how to read the contents of
the CF card as a memory block (of 512 MB) from a CF card reader and
save it as a file to a hard disk ? If I can do that, I plan to search
the file for any JPEG headers and terminators, and hope to be able to
save them as JPG files again.

Alternate solution path would be to try to rewrite the directory
structure on the CF card, but that sounds more complicated to me.

Anyone has any experience with CF cards here, or a good referral to
suggest ? So far I only found the CF+ & CF specification, but it's
information for card manufacturers, and does not say how to program an
access to the CF card.

Many thanks !

Paul

I take it you are reading the directory structure off of a card reader
?

you might want to review the recovery applications, though I haven;t
any experience using them (knock on wood I won't need one)

while many are designed to recovered deleted images, there are a few
that handle corruption , might be worth trying a freeware app first
and see if it can poke around and figure it out

the following are not recommendations, just pointers to what I found
in a quick google "camera flash recovery"

This one is also mentioned in the digital camera newsgroups. It is often
said to be "the best".

Thank you, I will try to sort it out...

I can read the directory structure from a CF card reader and from my
PDA.
