Corrupted jpgs from K100d

Morro · 07-07-2010, 12:03 AM

About 10% of the jpg shots I take come out corrupted. The lower part of the frame is shifted. I haven't seen anything like that in RAW and I'm not sure if it is a card or camera issue. Has anyone seen anything like that?

I've never seen something like that before- does it happen with more than one type of card?

That is very odd!

I have never seen anything like it.
Does it look that same on the LCD screen when you preview the photo or just when you download it on the computer?

They look good on LCD but corrupted on the computer. I tried different viewers (built in Windows Vista viewer, Picasa, Microsoft Photomanager) with the same result. All of the corrupted images came from the same Eye-Fi SD card.

Well that would explain it. Something must be wrong in the transmission of the images! I'm sure there's nothing wrong with the actual photos on the card, and if you used a conventional card, you wouldn't see anything like it.

I can copy the pictures via card reader and they are still corrupted. I suspect Eye-Fi may be too power hungry and that may cause corruption.. or probably something else.

I would assume it's almost certainly the card. Of the numerous file corruption issues I've heard of, 100% have been the card's fault. I guess it's possible it's a camera writing issue, but try re-formatting, or a new card. I used to use cheap cards and throw them out at the first issue. Now I'm using top-end sandisk, no problems yet.

Are the images still OK now when viewing via the camera's LCD?

If so have you tried uploading with the card in the camera using the USB cable -
and see if that might give uncorrupted images?

If all those fail perhaps you could try with the card in a known good reader and run something like MjM Free Photo Recovery - if the images are JPG (or perhaps try PhotoRec or Piriform's Recuva) and see if you can get back uncorrupted images?

Not sure it would help with pictures already taken, but be sure to downlaod the fairly recent (a month or to ago) firmware, that supposedly deals with a card issue affecting Eye-Fi cards.

Since I still have my K100D I'd be very interested

But I just went to both the USA and Japan sites and downloaded the K100D firmware
(I refreshed the pages to make sure I wasn't looking at any cached pages)
and both the downloaded .exe files were identical to the one I downloaded in April/2007 over 3 years ago -
I used ExactFile to verify the checksums - have I missed something?
