My 700D Will Only Recognise My Kingston SD Cards.

I've got some really weird stuff going on.

My 700D will only recognise my Kingston SD cards. I have cards from various manufacturers like Lexar, SanDisk and Transcend and an older 8GB Class 6 Kingston that also isn't recognised. I can't even format SD cards other than the two Kingstons pictured.

Though I'd check with you guys before sending my camera to Dr Canon.

Assuming that you have already checked the write protect slides...

Have you tried to format your cards on the computer? My PC says that they are formatted in FAT 32.

Try formatting one in FAT 32 and see if it recognizes it. Then, reformat it on camera.

Thanks Gerry,, I'll try that..

Gerry,, tried a FAT 32 format,, no difference. Camera still won't access the card.

In the initial post you showed what will work. How about showing us exactly won't work.

All these aren't recognised.

I had this problem once. With a brand new (never used) card, that I formatted first on the PC. My 60D refused to recognize it. Thankfully my old P&S did, I used it to format the card and then the 60D accepted it and I formatted it once more with the 60D. It still works!

It may work for you (if you haven't tried it already...).

If you have a card reader (or a card slot in a PC) check a card for two things.

1. It should be formatted to FAT32.

If formatted by a camera it should have the following directory structure.

I tried to re-create the problem using a SanDisk 8 GB card I keep in my wallet as spare. I couldn't.

I formatted the card on the PC in FAT32. No Canon directory structure as described above. Put it in the camera, took a shot. Voila! Directory structure established, photo saved.

I formatted the card in NTFS! Put it in the camera. Camera says that it doesn't recognize the card, offers to format it. I go for a Low Level format (I always format low level), take a photo and voila! Directories/photo saved.

Since I am running Linux, I formatted the card in ext4 (Linux File System, one of the many). Normally, a drive/card formatted in ext4 would not be detected in a Windows PC. I put in the card in the camera, it said it didn't recognize the card, offered to format it, I accepted, and I took a shot! ...Voila... Directory structure/photo all there.

I give up! I'd be inclined to say that the mechanical switch which detects the card insertion is broken, but you have two cards that work!

Maybe you could re-flash the camera before you pay Canon?

This may be a desperation move, but I'd try it before paying Canon to fix it.

Blow FORCEFULLY into the card slot, several times, with and without a card present. (I suggest doing this a secluded spot, by yourself.) Perhaps a speck of something is stuck somewhere it shouldn't be.

I've tried that. No good but thanks..

Thanks Tom.
