Why not do a test and see if it works with 2 cameras?

Thanks I will when I get to Texas. I just sent a couple out to myself.

My cards are camera specific. I do format them in the camera in which they are intended, after transferring the files to hard drives and verifying that the files transferred error free.

Yep - formatting the card takes only a matter of seconds, doesn't hurt anything, might help, so why take the chance?

I was updating software for my D810 and D500 with a card. I used it an erased the stuff on there after using (the updates). My question is, if I have formatted a card in my D810, and then decide I want to use it in a different camera, the D500 or even the Canon I have, does it matter? I usually don't format cards to begin with, I just stick them in the camera and they work fine.


In general, it's good practice to ALWAYS format a card in-camera before starting to save any new images to it. There can be issues switching using them between models and especially between different manufacturers. You've been very lucky, if you haven't had any problems. I've often loaned a card to friends using them Nikon, Pentax, Olympus etc. and they would no longer work properly in my Canon.

I also never "erase" or "move" images off cards. I "copy" them, so the originals remain on the card until I'm sure they have all been copied off successfully and safely. So I'm simply in the habit of formatting every card, every time I install it in a camera. Don't know about Nikon, but my Canon have a user-definable page in the menu... and the very first item on mine in all my cameras is "format card". It takes me about 4 or 5 seconds to insert a card and format it. Formatting does not remove old images... It just marks them as "okay to overwrite".

Just to clarify. High level (quick) formatting deletes the INode pointers in the allocation table - the data is still on the card, just the allocation table has been changed. A low level format (which takes longer) typically writes zeros to every location on the card and the data is typically irretrievably lost. The format creates a file system (not an operating system), which may be FAT16, FAT32, ExFAT, NTFS or APFS (Apple), etc., and the particular file system you choose will govern the max file size you can write and whether multiple different compute platforms can write to the card. Each camera creates a folder under that file system, so there may be multiple folders from different camera manufacturers on the same card. I have never found this to be a problem - I have cards that have been written to by different manufacturer’s cameras and can be read without issues, but I cannot guarantee that is true in all cases.

I found my older Kodak 750DX that used SD FAT16 , 2gb max cards. I tried to reformat a 16gb SDHC C4 FAT32 card back to a FAT16 format. I could not reformat it. WHY??? Some how the computer knows that you can not go back to a FAT16 format. I googled the problem and many have tried to do the same and most have given up, again WHY? Any one with an answer?

As noted on another stream, I haven't formatted a card for years, in camera or out. No problems.

Because FAT16 has a max volume size of 4GB.

Each line of camera by each manufacturer typically uses diff software/firmware in their bodies. Why take a chance? What does it cost in time, energy, or money to spend the 10 secs to format in camera?

Follow the yellow brick road instead of the thread...

I'd rather be safe, so I reformat after every shoot has been downloaded. When I changed from Nikon to Olympus, I just reformatted the card from my Nikon in my Olympus with no issues.
