I was shooting about 250 pictures at a Pirate Festival when 3 times at random after a shot the hour glass appeared on the LCD for about 20 to 30 seconds. Even if I turned the camera off and then turned it back on the hour glass was still there. The memory card was a ScanDisk 32G Extreme Pro Compact Flash 90MB UDMA7.
I've read about other experiencing this, but never had it happen to me -- until last week. In my case, I didn't see the hour glass, but the camera "packed up" and the view through the eyepiece was black! My LCD indicated that I had a corrupted flash card. I turned the camera off, removed the battery, put it back in, and activated the on-off switch again. The camera came back to life.
On getting home and downloading via a reader, I had difficulties doing so, and had to download a total of only 25 or so RAW and medium JPG images in sections of 10 or so pairs at a time. I noted that one JPG was corrupted and could not be downloaded regardless of how I tried.
So I formatted the card in my computer and then again in my D800. It's a Lexar 800X, 8GB, and I'm watching it like a hawk. I've never had a flash card hiccup, unless having one fall out of my pocket in Iraq counts!
So I recommend formatting the card again in your camera and watching it carefully.
just some observations regarding MMC/SD/CF cards...
I am currently designing a new product for my company that involves a MMC/SD card support. I have a micro 16gig MMC/SD card installed.
There are times where I can cause the SD card (remember, it is not a passive device but an active "product") to lockup with no reason and that also causes the data to become garbage on the card. I cannot explain why as I follow all the "rules" about how to communicate with the device as the electronic level. When I get the SD card in that state, I have to reformat the card for it to fix itself...
I've looked at the scope and captured all the SPI data and it all looks good...no bad timing etc...beats me.
Some some thoughts
- If this keeps happening, it may be a bogus SD card, try a new one - reform the SD card and see if that fixes it - try a faster card, but again, that should not matter as the MMC guidelines go over the correct ACK/NAK timing handshaking etc. - Does the same happen with the CF card? The CF card is fundamentally faster and employs more data lines (ie. parallel vs. serial )...
It is likely that the flash card/SD card was corrupted when you formatted it on your computer instead of within your camera using your camera software? I never let any of my computers touch my flash or sd cards. I have experienced D800 card failures when they (Scandisk extreme pro) have been inserted into my Apple OS-X systems. In any case, the D800 will transfer files from your cam body card to your computer fast enough that you will not need to put the card into the computer, or into an external card reader. Just lock all you cards after shooting, and then transfer the files to you computer using the same camera body the images were originally stored on. I would never use a flash card again, given the infinitely better SD cards now on the market.
When I first got my D800 I had this issue also occasionally. It got so I felt I could hear a different shutter click sound when it happened and I knew even before I even looked at the camera that it had locked up.
After awhile, I realized that it was only happening when I was shooting with DX lenses (I still had two). Since I quit using them on the D800, I have never had it lock up again.
I know this is a totally different path than everyone above has taken you on, but I just wanted to present an alternative option.

I experienced similar lock up issues that I traced to a lens. Something to check into.

Hi Bob, I have no insights but I've suffered the same issue. It's happened 3 or 4 times in 1600+ shots and IIRC it occurred in one shooting session. I shot 120 shots last night and had no incident. I'll list my parameters to throw my scenario into the mix:
- Camera: D800E SN 3011xxx with 1600+ shots on the odometer - Firmware: A=1.00, B=1.01, C=1.006 - Memory: SanDisk CF Extreme Pro 32GB (NEF-primary), SanDisk SD Extreme Pro 32GB (JPG-secondary). I have 3 identical sets of the same memory which has been used although I can't recall which set was being used when the issue occurred. - Memory ONLY formatted in camera. - Memory purchased from B&H although one SD card was purchased from Newegg. Source would appear to be legitimate, although one could argue the Newegg source. - Memory stays in camera or memory holder at all times except for ammo change. Image transfers only from camera to PC. - No image corruption after incidents - Lenses: Only 2 FX lenses used, 28-300 and 16-35, since the beginning. Both lenses new. I shot 120 shots last night using both lenses and did not suffer an incident. - Maybe it's my computer training, but I definitely would NOT turn the camera off during an hourglass display - too much stuff could be happening electronically. Now if it was 30 mins or an hour later, I wouldn't hesitate to shut it down, same as computer rules.
If there's one factor I need to track down, it would probably be the 3 sets of memory. I'll use set #2 tonight and see what happens. Hope this helps a little!
