Memory card unreadable on Canon EOS 500D

Hello, thanks again, I really have tried everything.
I ordered the device online (Digixo), it seems reliable.
Tomorrow I plan to contact them. I also think I'll reach out to Canon France's support service.
My problem, relatively speaking, is the time I'll lose dealing with this incident and possibly the disappointment of not having a device for the holidays.
I'll keep you updated. My experience might help others.

Good evening!

Of course, the card must be of a type compatible with the device.
SD should work, SDHC needs to be checked in the manual.

I don’t have a Canon, but if it works like mine (Panasonic Lumix), there is a small preparation to do with the new card. Panasonic calls it "formatting" the card. It’s not exactly formatting, as the retail card is already formatted, but rather creating one or two predefined folders on the card where the photos will be stored.

You need to read the manual, probably in the section "memory cards."
Normally, the operation is initiated from the device’s menu, probably the configuration menu.
It is possible that a card previously used on another device may not be recognized spontaneously. After formatting, it should work, but be careful, the previous photos will likely be lost.

Finally, it is possible that the device needs to be configured to work with the card instead of the internal memory. But normally this should be automatic as soon as a card is present.

Definitely do not format the card on a PC unless you know exactly what you are doing! ..

Wait for other responses; you might be contacted by a Canon EOS 500D owner...

Good luck...

See you!

PS : I just downloaded the manual (great device!!)
The formatting of the new card is on page 40 of the manual! ..

Thank you for your response. I did try to format this new card, but "the device won't let me," I also checked that the write protection switch was properly in the up position... anyway, I don't know much about this, but I'm trying to follow the manual. I also placed a working SD card from a compact camera = same problem!
I'm surprised there might be a hidden defect at this level; I think it's more likely something I'm not doing right.

Hello
normally SDHCs are compatible
"Memory support: SD-SDHC, guaranteed compatible with Eye-Fi cards"
But I don't know more. Sorry

Is there any message?

Re

It can happen that a memory card is faulty. Several like that, it’s highly improbable.
This Canon is indeed designed for "standard" SD or SDHC cards (not specific to Canon, as might have been feared).
I assume you charged the battery correctly before use...

This looks (in my humble opinion, but I willingly accept disagreement):

- either a problem of bad contact between the SD and the Canon: I assume you inserted the card the right way, AND all the way until you hear the "click" (manual page 31).
- or a write-protected card (although the message should logically be different!): I assume the write-protect switch is fully pushed in the direction opposite to "Lock" and that you checked!
- or probably a card format issue not recognized (this is not about size, but about the organization of sectors on the card: several are possible).
If I understood correctly, you have only tried cards that have been used elsewhere, and their "preparation" might not be suitable for your Canon?
Have you tried a new card?

==>> With a new card (if it doesn’t work) or one that has been used (in which case you’ll lose its content!!) try "LOW LEVEL formatting" (manual page 40), and if that works, then do a normal format afterward. Then try taking a photo in any mode.

If that fails, it is unlikely that you forgot to do something, and I think it’s a hardware issue...

Did you buy it at a local shop? Go there and demand they demonstrate it for you (you might have to pay for a new SD card).

Did you buy it by mail order? Do you trust this supplier? Try contacting their customer service. Don’t forget you have a 7-day withdrawal right, but it might be too late... Otherwise, there’s the warranty...
But I think you can contact customer service at any Canon shop, if you have your dated proof of purchase.

Don’t regret buying this camera, I think it’s excellent. You might just be unlucky. Let’s hope your supplier is reliable, and is not selling defective batches...

I hope I was overly pessimistic!
But I think you’ve done enough to be entitled to contact customer service right now, without fear of looking ridiculous...

Good luck!
