Have been using my Canon D5 Mark III with two cards . Up to now there has been no problem transferring photos to my computer. Suddenly the computer does not recognize the card preventing the transfer of photos . Is the card now corrupted ?

It seems that the routine for most people is:

1-Format a fresh card in the camera
2-Shoot pictures
3-Transfer pictures to a computer
4-Backup the pictures that are on the computer to external storage
5-Reformat the card in the camera to remove previous files and prepare it for the next shoot.

Is this your practice? Did this same card work before?

Does the card still work in the camera? Can you view images in the camera? If so, plug the camera into your computer to get the images off.

Does the 2nd card work in the computers card reader?

1. At the risk of getting my wrist slapped: You did format the card in-camera before starting to take photos?
2. More wrist-slapping risk: Did you set the camera to select the card you wanted to use to record the photos? Maybe they're on the other card.
3. How do you transfer the photos to your computer? If using a card-reader, try connecting the camera with the supplied USB cable. If using the cable, try a card-reader.
4. If none of the above works, does your camera have the capability to copy photos from one card to the other in-camera? If so, try that and see if you can read the second card on your computer.

I had similar problem and discovered there is an on/off switch on the side of the card. Like a small metal slider. Moving this solved my problem.

The second card works fine in the camera and in transferring photos . I use a card readerDynex which I have for years without problems of any kind . All of a sudden the 64gb has been denied access to the computer.computer does not recognize card? I do not remember fiddling with dials or controls on camera or computer . One of the mysteries I hope that can get resolved .

Have you tried rebooting the computer and then trying to read the card?

Computer guy here. Try a cold shutdown, get a cup of coffee (this is a very important step), fire the computer back up. If this doesn't solve it, I agree, see if you can read the card in your camera. If you can, plug the camera into the computer and download. Then format the card in the camera and take a few test shots to make sure it's working. If not, SD cards aren't big enough to make a good paperweight, but they are cheap enough to replace, which is what I do at the first sign of trouble.

Some time back I downloaded a program called "Pandora Recovery" to deal with corrupted SD cards. I've never used it and in fact I've never installed it in my PC - I just downloaded it with the plan to install and use if I ever had a problem like the one you describe. As I recall, it was free software.

Eliminate the card reader as the problem by using the cable. I find my card reader a PITA and always use the cable.

I assume we are talking about SDHC card? How old is the computer? You may need a driver for a PC. Has that same card worked in the computer before? What OS are you using?

I have had a host of problems with 64 GB SD cards from different manufacturers in a variety of devices, and I have stopped using them.

It seems to me to be a problem with limitations of the file system structure.

Theoretically they should work, but they aren't reliable in my experience.

They work flawlessley on my MAC, I only use them to shoot start trails. I would buy name brands and stay away from cheap knock off's.

I have this problem on my iMac. It will only read the card if I have the card inserted in the card reader when I start up the computer. If I try to use the card reader after the computer is already running it won't recognize the card.

So, try having your card in the slot and then restarting your computer.

Also, I have things about Dropbox messing up the card reader.

I hope this helps.
