SD woes

Sun, Sep 4, 2022 3:01 PM

Last spring we took a walk in Morris Arboretum, where the spring blossoms offered lots of photographic fodder. Alas, when I got home, the card had thumbnail JPGs on it, but no DNG files. As usual I erased the card (SanDisk Extreme Pro) in the camera after transferring the files to my computer.

Last week we toured Winterthur, a beautiful DuPont estate about an hour away. Again I took about a hundred photos. When i put the SD card into the reader, I got a screen full of thumbnails from Winterthur and the flea market in the parik a couple of weeks ago, all stirred together (even though the card had been erased).  No DNGs.

I have four SD cards, of which three were indistinguishable until I numbered them yesterday. I checked each of them with the Mac Disk Utility, and they all passed.

Any ideas apart from buying a new set of cards?  Is there any way to distinguish a card failure from a camera failure?

Mike,

Three of my four cards were indistinguishable, until I numbered them yesterday.

Methinks I will waste some electrons today shooting on each of the cards to see if one is faulty.

Doublecheck camera settings to make sure nothing was inadvertently changed?

The most obvious reason for a perfectly readable card to contain only JPGs, no DNGs, is that the camera has somehow got set to only write JPGs.  I assume you checked that, but ...
(Or, depending on which camera body you have, to write JPGs to one card, and DNGs to a different card)

Progress so far:

  • Tested all 4 SD cards.

One occasionally lost its connection to the camera when I wiggled it, and another seemed to fit loosely in the slot and its connection seemed unreliable.

I threw them away and ordered 4 new cards from B&H.

Curiosity: How old is the camera you're using? How much use does it get? The SD card cages in the camera do wear, over time, as do the SD cards themselves, such that the card can get loose or the contacts become a little flakey.

I've had this happen on only one of my cameras over the past 20 years, and only had one or two SD cards fail on me, but a lot depends on exactly how a particular camera and card are handled. That particular camera, for me, was purchased used and got used a heckuva lot.

Certainly if a card is loose enough in the slot to lose connection when wiggled, or even just a loose fit in the slot, something is happening because the SD cards should fit the card cage fairly precisely.

It's a good practice to always mark all cards and batteries used with a camera and use them in ordered rotation with only that camera. That way, as problems develop, you can easily identify which components or cameras are suspect. I do this particularly with batteries, but my cards are all marked too. (I'm now using mostly 64 or 128 G cards and that's so much capacity, for my current shooting practices, that I only rarely even need a second card in my bag!)

Rick, I think Godfrey may well be on to the problem. The card contacts
in the camera may be a bit grimy. Plastering an SS card with one of
those electronic cleaning agents (Like Spanjaard LektroKleen) & putting
it in and out a few times may help. I have solved USB contact problems
like that.
