I saw this alot whilst working with jessops. This occured across all
camera
manufacturers and card manufacturers.

software called "don't panic" image recall and sandisk rescue pro were
useful. Even a card formatted several times could yield usuable 6 month
old
pictures with rescue pro.

There are trial versions available for download.

If the user is even half way computer savvy none of the following make
any sense to me.

1.If using a card reader use it to read only.

It will delete just fine and should do so without problems. For the
non computer savvy I would suggest not formatting in the reader.
Otherwise it'll format just fine with told the proper file structure.
Most cameras will create their own directories the first time the card
is used.

2. Copy and paste do not 'move' pictures.

Use common sense. Copy to one file and move to the backup.
It saves time and operations. It also leaves the card clean.
(This has the advantage of creating a backup while deleting the files
from the card) It's a good reminder to create a backup right off the
bat instead of "later" which often means it'll be forgotten.

3. only delete or format the card inside the camera.

Why? I do all of mine on the card reader.
As I said earlier. For those who are not computer savvy this makes
sense for formatting, how ever the card, or the camera doesn't care if
you delete in the camera or the computer and it should change nothing
that would confuse the camera as using the wrong format would..

4. Format the card regularly don't just keep deleting.

Now this one makes no sense at all. There is no need to format a card
unless something has crapped out and trashed the directory system.
Even then, normally you can delete the offending photo and then access
every thing else. Deleting all the photos, or moving all the photos
leaves the card clean with the exception of the directory structure
and that does not need any house cleaning. Deleting all the files
eliminates any possible fragmentation and slack space. Formatting
doesn't hurt anything, but it's not necessary either.

In something like three years and over 60 to 70 Gigs worth a year I've
not had a card failure. I had one trashed photo that prevented me
from reading the card due to turning off the camera during a write. I
deleted the photo and the cameral was happy.


stick to name brands such as sandisk. lexar weren't so good for canons
for


I'm still using the same 3 cards (two 250 Meg and a one gig) I
purchased with my Oly E-20 N when the Oly first came out. The 250s
are I/O Data and I don't remember what the one gig is.

a while.
pny was a brand that was the worse offender regarding camera or card
format.
avoid any shop brand or vendor brand media. Micron have a good
reputation
also known as 'crucial'. kingston aren't too bad and viking is a
definite
no. Different card readers have different level of success. I have had
this problem with all three readers i have. Sometimes remove and reboot
pc

If you have to reboot the PC there is either a USB driver problem, or
a configuration problem. (or a bad connection) However USB is only a
kinda, sorta, standard and variations can exist that may not be
interchangeable.

and everything works again. I prefer to use cameras in a mode that the
pc
sees it as a drive and not a camera. Don't bother with fancy download
utilities just use explorer and copy and paste.

As do I, but I haven't hooked a camera to any of the PCs in a very
long time.I just stick the card in the reader. Both the Oly and D-70
have tiny USB connectors and I'd much prefer to use the much more
rugged card.


Thanks Ian. I gather that is definitely a problem with the Lexar Compact
Flash card and/or the reader then? I was concerned that it might have
something to do with my D70.

The D-70 should take about anything you feed it. I have a no name,
reads everything, USB card reader built into the machine in the shop.
Other than slow, it works fine. This one has a SanDisk USB2 reader
that is fast. Prior to that I had one that came in the Oly camera
package. It too worked fine, except for being slow.


Pat

I was only aware of a lexar/canon problem. Swapping cards between different
cameras especially different brands of camera is also a no no.

<sigh> I regularly swap cards between the Oly and Nikon D70. Each
creates its own directory system and they happily coexist and will
even work swapping back and forth between cameras in a single shooting
session.. This may not work for all cameras, but I'd not be afraid to
give it a try. It'll either work or it won't. The worst that can
happen is you have to reformat the card.
