I picked up my M9 to shoot some photos, and it already had a bunch of photos on the SD card from a week ago. Took about 20 photos today, reviewed them on the LCD display, then turned off the camera. Transferred the photos from the sd card (Sandisk Extreme SDHC 16GB) to my external hard drive. Then I wanted to import the photos to Lightroom. No new photos detected, only the old ones from a week ago. I then opened the hard drive, and no new photos there either!
Since I had formatted the sd card, I downloaded EaseUS Data Revovery, and managed to rescue some of the photos from the sd card.
However, since I read on the internet that some Sandisk sd cards can be problematic, and that one never should continue to use a card that one has had any problems with, I decided to use a Transcend SDHC 10-speed 16GB card. I put it in the camera and formatted it. Tried it out by taking and transferring some photos. However, when I put it in the M9 again, the camera said: Warning, SD card locked! Took it out, but no, it was not locked. Inserted the card agin, and the camera said: Warning, no SD card. Tried inserting the card 5 more times, same warning. On the 6th try, it worked, and I could take photos.
Now, are my cards too old or damaged? Is my SD-card-slot in the camera faulty? Or could it be battery related (it was above 50%). I have firmware 1.196, is this the latest?
Which SD cards are the best?
Extremely bummed, a camera one cannot trust is worse than no camera at all!
