I have filed a problem report with Nikon, but 72 hours later, no reply. Here is the issue as I described it to Nikon:
Repeated Multiple "Card Err" on D7000
I have been experiencing repeated occurrences of "Card Err" messages. It usually starts with a "Cannot write to card" message. I've had the error occur against both slot 1 and slot 2.
The camera is configured to write RAW to slot 1 and Small Basic JPEG to slot 2.
The normal card configuration I use is a Class 10 SanDisk 32GB SDHC card in slot 1 and an Eye-Fi 8GB Pro X2 in slot 2.
However, I have tried the same model SanDisk card in both slots, I've tried various combinations of SanDisk 32GB Class 10 cards and SanDisk 8GB Class 6 cards, and I still get random failures.
Sometimes all I have to do is turn the camera off, remove and reinsert the card, and it works. Other times I have to also reformat the card. Simply turning the camera off, waiting, and turning it back on accomplishes nothing.
This just started this weekend -- the first time I've really put the camera through any workout. All occurred while the camera is mounted on a tripod using a SB-900 flash on the hot shoe. Except for "fixing" the card errors, the camera has remained on the entire time. I experienced about 10 to 12 failures (lost count) over a period of about 500 shots.
This problem is both annoying and unacceptable -- especially when I loose work!
Please tell me this is a known problem with a simple and fast fix!!
Anyone have any suggestions?
