5D mark III problem - 32gb sandisk extreme pro destroyed

[marooni]

I encounter a problem with my 5D mark III that destroyed one of my cards.

The problem appeared when I locked two pictures on the card and after that I erased all pictures fron the card except the locked ones. The erasing proces started and after few seconds (10-15 sec) appeared the message "the card is not recognisable". Tried different approaches: close and open camera, remove and put back the card, try to format the card on 5D mk II, try to format on MAC, PC, tray to accese it with IPAd, but the card remained not recognisable by any of the cameras, pc`s, mac`s or Ipad.

Is just broke.

Does anyone knew something about this issue?

Thanks,

Robert

Try Sandisk's RescuePRO first. A 1 yr license comes with each card, if you do not have a copy PM me + I will give you one of mine.

what makes you think the canon broke the card?

counterfeit sandisk cards (approximately one third are fake says sandisk) show this behavior quite often.

that app is for rescuing deleted files. he can´t even access his card.

Have you used it?
It will erase on a card and set all the memory cells to zeros. and will then reformat it. It might not fix his card, but its worth trying.

If the above doesn't work, open up windows/system32/diskmgmt.msc. That should recognise drives/cards not otherwise recognized by the computer.

A few thoughts.

First, "destruction" implies severe physical damage. From the subject, I was expecting to read about the magic smoke being released from the card, or something along those lines. Nothing of the sort happened.

Next, as others have noted, the chances that this is the camera's fault are basically nonexistent. Zero? No, of course not. But the odds that even something like a cosmic ray caused the problem are far higher than the camera being to blame.

And, last, once a card has gone tits-up like this, I'd never trust it again. If I could get a refund or replacement, fantastic. If not, I'd just toss it, write it off, and move on. Part of the cost of the business.

Cheers,

Have you used it?.

yes... and if the OS did not see the card it will do nothing.

I did the best next thing: I tried the same thing with another card, an old 2GB Sandisk Extreme III: took some pics, locked some of them and erased the card.
Same thing happened: the card is not useable anymore.

This is telling me that my 5D mk III have a problem with locked pics. I do not know if this is a general problem, with all 5D mk III`s, but with mine is. I will buy tomorrow some cheap cards and try again the same thing.

True, Jesus did not appeared on the screen. I am still waiting! :-[

Looks like the cosmic ray caused the problem!!! 8)

Maybe you did not understood that this card is not useable anymore. How can I trust the card again if is not working?
I do not care about refund and I know well the cost of the business. I just posted a problem for a discussion hoping that someone else have the same problem or have a solution.

Don`t let negative thinking clouded your mind. Let the Force be with you! ;D!

what makes you think the canon broke the card?

counterfeit sandisk cards (approximately one third are fake says sandisk) show this behavior quite often.

The card was bought from an "authorised store" and was pretty fast. I do not think it was a counterfeit one.

And I think that camera broke the card because did the same think when tried with another card.

Perhaps time to contact Canon Support? If you have another camera you can take a video with, maybe take a video and show exactly what you are doing and the way in which are doing it.

It's screwy, but authorized retailers were also selling knockoffs a while back. It was a big problem a few years back, so I'm not sure if the issue was ever fixed.

Never tried to lock pictures, and thank you for the warning.
If this happened to two different cards, Canon needs to explain this.
The first one is/was ~ $ 300?
Painful.
If you get an answer, please post it.
Good luck!

If the above doesn't work, open up windows/system32/diskmgmt.msc. That should recognise drives/cards not otherwise recognized by the computer.

Similarly on OS X, if you open up Disk Utility (under Applications/Utilities), it will sometimes show media that isn't properly formatted or that has corrupt partition settings. If it does show up there (note that it may be greyed out), you can click on it and erase it. Be sure to use MS-DOS format and MBR as the partition type as the camera won't work with a Mac-formatted card. If the card doesn't show up in the list, there are bigger problems afoot. I also recommend contacting Canon EOS Support as they might have additional suggestions. Last but not least, you should be able to contact Sandisk for a free replacement.

I took a few photos using a old cf card, protected two of them and erased the others. There was no problem, I tried this several times and everything worked.

Since it happened twice, I'd suspect the camera has either a hardware or firmware issue. It might even be a bent pin in the camera that causes the issue.

I had a similar thought but I had found it scary and disappointing (for the 5DMkIII) at the same time! This is not the first time I read 5DMkIII involved in bent pins
My 5DMkIII is fine but I am very careful when I have to insert a CF. I didn't use to be afraid and pay extra attention with my 40D and 5DMkII (and I removed CF cards a lot).

 

[jdramirez]

I want a 5dmkiii and this wont' stop me, but i'm pretty sure what I'm going to do is just transfer my photos via usb cable. First of all, I don't have a CF card slot in my computer, 2nd, bent pins have scared me since I heard it ruined a canon xti or something old school like that.

It hasn't been determined that a bent pin is involved, its just one of the things to check. Actually, its very unlikely.

I am using 5D3 every day with 32gb Sandisk Extreme - via card reader. I have my 5D3 for one year just now. I had never have a problem with putting a card in and out. It is just about to do it carefully. It seems like "hoax" for me to read about some bent pins.
