Now that more and more cameras have dual card slots for backup, I was wondering how many people have actually had to use them?

I'm not talking about physical accidental damage, just want to know about cards becoming unrecoverably (is that a word) corrupted in the camera.

I've never had it happen to me...​/photos/jackhenriques/ (external link)

I have 3 Kingston Elite Pro CF cards that became unreadable. I reformatted one of them, but it quickly became unreadable again.

My Sandisk CF cards have not had a problem

I have had some transcend cards years ago that would give me corrupted images and once or twice say unreadable, I could reformat them in camera and then they would work. But they had around a 1-2% corrupt image rate consistently.

I've had both SD and CF cards fail, but I picked CF because I've had 1 more CF card fail than SD (I use CF cards more than SD).
The Sandisk CF cards (2) were replaced under warranty by Sandisk, no questions asked...
None of the others were replaced, other than what I bought to replace them.
I use mainly Transcend cards now. They have worked without failure, so far.​t (external link)

I've had a sandisk CF and SD card go bad on me. And they were genuine ones from best buy. The SD lasted a year, the CF only a week.

I've had 3 sd cards fail on me, but none of them were sdhc cards and they all happened more than 10 years ago. 1 wouldn't read or write and wouldn't let me format it either, another was corrupted during upload in a card reader and I couldn't do anything with that either, the last one had the lock switch break off and a bit was loose inside the card so I wouldn't risk using it in case the loose bit came out into the camera.

I use all 16Gb Duracell CF and SDHC cards now but I have got a 4Gb Sandisk card a 16Gb Verbatim CF that would only be used when the Duracell cards were full up.

I had a SanDisk CF card fail first time out. No problem as they have a lifetime warranty but it takes
a while for replacement. You will need your receipt from a reputable source no e-bay purchases from
who knows where.

I have had both CF and SD cards fail. I have cards from over 6 different companies. Transcend seems to be the worst. I have had several SD failures. I have over 20 4gb cards, and have had at least 5 failures. I also have a 32g 600x CF card that failed, was replaced and now every 3 times I put it in the camera, I get a message it needs to be formatted. I take it out, put it back and it works. I no longer use it, as I don't trust it.

The SD card that came with my camera kit failed early, within a few weeks, but I haven't had one fail in 20k shots since then (3 yrs).

One CF card out of dozens in over a decade. it was a 256MB Kingston. It failed last year. From the capacity, you should have an idea how old it was.

It was NOT the Viking CF I dropped in the ocean.. which still works (though I don't use it as it is very small too.)

Two SD cards of mine have failed, a 1GB and a 2GB. So early ones..

I voted no, which is a bit of a lie as I have had a CF card fail on me, but it wasn't the card's fault. I had it in a iPaq PDA (that, children, is a small pocket-computer we used to use in the days before smartphones). I'd told it to delete some files that I didn't want deleted, so I pulled the card. Managed to scramble almost everything on the card (luckily I had a fairly recent backup).

I had a Lexar card fail, and the company replaced it within 4 days.

Yes-- I thought I had lost the first half of a state quarterfinal football game on a SanDisk Ultra3--It reviewed in camera but came up with a read error in the computer and after that it would not read in the camera either.

I was able to recover the images with RescuePro that came with the card--and then it went straight in the trash. ;)

Over the last 10 years I have had 2 dozen SD cards made by Kingston, Patriot, Sandisk & Transcend. None have failed. Now, I have 7 cards, 5 Sandisk & 2 Transcend
