Had a wonderful photo session with a beautiful model, except for one major problem. When going over the set to make a copy, I discovered some images did not write correctly.
It was not one or two, but about 234 of 1163 images (or 10%) that appear to be lost and gone forever. I have tried two different card/image recovery programs to recover at least the last set, but no luck.
I am open to suggestions:
What I have been able to determine is apparently my Sandisk 1GB Extreme II SD card would fill up and then it or the camera would continue to let me think it was writing images to the card for about 30 more shots. I was also using a Sandisk 2GB Ultra II CF card and a Lexar 1GB 40x WA card. As far as I can tell these two did not lose any images (I know the Lexar didn't since I only used it once and can acocunt for all of it's images). Since I would alternate between the 2GB CF and the 1Gb SD cards (except once when I used the Lexar near the end, when I got impatient) I am pretty sure I know which ones are which. My first 247 images were fine, then I started losing them. In other potential causes my SD card was the one in use when I went over 10,000 images taken (at about the 298 image mark (so I had appearently been writing bad images when it went over) and that created some weird files on the card, but I formated in the camera after transfering what I had at that point. Given that I seemed to get 150-180 good images then a batch of 50 bad images, I know my 2Gb card will only hold about 120 at most, usually 110ish, my SD card usually gets around 48-56 images, it is fairly easy to figure it was the SD card. I shoot Raw plus Jpeg M2 Level 8 compression. The camera got turned off and on when I changed lenses (which didn't happen until late in the session and once between cards. The cards got formated at least twice in the camera, which is rare, since I usually don't find the need. Once before the session to make sure the cards were clear (this I almost always do) and after it went over 10000 images because of the weird files on the sandisk card (the weird files did not reappear until I tried the second recovery program - but I have seen those before when doing a recovery).
So in short form
- Only the SD card had this problem
- it happened close to the 10000 image mark when the camera told me to change folders
- It appeared to let me overwrite the card, but the first images taken on the card were okay, overwite images are bad.
- I can't get it to repeat today, despite several attempts.
Other then the 10000 images passing, I did nothing different then in past sessions with the same cards.
That's all the info I can think of,
First anybody have any suggestions on how to recover the images (if they are there at all)?
and Second anybody have suggestions on what might have happened and how to prevent it in the future?
An $8000 camera with pro cards should not be doing this.
