I'm totally perplexed. My 32 gb card was fairly full at over 28. I had just downloaded some images to my iMac. I pulled the card out without ejecting, but I often do that with no issues, as I was only downloading images rather than writing anything to the card. I took probably 30 more Fine + RAW images. I shut off the camera and stuck the card into the computer, and there are no image files from today. At first I thought the lost images maybe were not picked up by the PhotoMechanic ingest, so I looked in the finder. Not there on the card. I looked on the entire hard drive for any files created today. Nothing. And when I was shooting the images, I did review the last shot image, but never browsed the images.
I tried Disk Drill, but that did not find any new images, although it did find older deleted images.
I just downloaded Remo Recover Photo, and it will take some time more to run.
While it will be sad if I lost my pictures today, it is a scary thought that this could happen again.
This seems related: Lost photos on my SD card while shooting with Nikon D80.
However, I didn't delete any images nor did I get an file system or camera errors. It's just like I never took the photos today.
UPDATE: Great news. I saved the images! Remo Recover Photo did find the images, so I knew there was hope. Here's some info:
- Disk Drill did not find anything, as it was looking for deleted images.
- Remo Recover Photo did find the images, but it costs about $80 to recover the images. A fair price, certainly, if you want a GUI program.
- I decided to try out Test Disk and Photo Rec, primarily based on the positive comments in other threads and it seemed like a good idea to back up the partition.
- Test Disk and Photo Rec (photorec) are strictly old school command line programs, BUT they turned out to be VERY easy to use. They are menu driven, so it's not like you have to figure out the exact program arguments.
- I thought the program was Windows based, but it is definitely not only for windows, and the windows program uses cygwin, which I'd rather not use. (Cygwin makes windows seem like Unix, and I would not like to have that extra layer).
- When I used photorec the first time, I only scanned for deleted files, and sadly, that did not find the missing images. Yikes!
- There's a second option to pull all the images off of the disk. That one takes way longer. Yipeee! The images were recovered.
- In order to find the images, you have to scroll through all the recovered images. I found that the faster way to do this was to use the "Coverflow" Finder view and to then hold the arrow key down. Amazingly fast. This is way faster than browsing with the Remo Program. Once I identified the images, both Raw and JPG, I copied them to another folder, and then I imported (ingested) them in Photo Mechanic.
I was worried that the match up with JPG/NREF (raw) would not work, so I did a test of a couple of images, and it did work, maybe because I configured the import to rename the files based on the date of the shot. Thus the JPG and NREF files got the same base name. Nice!
So what's interesting is that images were not accidentally deleted, but they just were LOST on the disk. How could that happen??
I launched the Mac Disk Utility app and fixed the disk (SD Card). This is what it said:
Verify and Repair volume “NIKON D5100” Checking file system** /dev/disk3s1 ** Phase 1 - Preparing FAT ** Phase 2 - Checking Directories ** Phase 3 - Checking for Orphan Clusters Found orphan cluster(s) Fix? yes Marked 38776 clusters as free Free space in FSInfo block (661485) not correct (700261) Fix? yes 807 files, 22408352 KiB free (700261 clusters)
* FILE SYSTEM WAS MODIFIED * Volume repair complete.Updating boot support partitions for the volume as required.
TestDisk reported the following:
Disk /dev/rdisk3 - 31 GB / 29 GiB - CHS 62333952 1 1
The harddisk (31 GB / 29 GiB) seems too small! (< 4138 GB / 3854 GiB) Check the harddisk size: HD jumpers settings, BIOS detection... The following partitions can't be recovered: Partition Start End Size in sectors

So a happy ending, but this definitely was pretty stressful.
So the final question is what should I do with the SD card? Reformat it on the mac or camera? How? Safe to use?
