Memory-card randomly stops recording??

I bought a new memory card not too long ago. It's a 32GB (Class 10) Sandisk. It's been having this problem where it will randomly stop recording. Now, I don't exactly no how to explain it, but this little icon will pop up on the screen that I know means it's having trouble writing to the card fast enough (because I've seen it happen with lower class cards). I've formatted the card and it still happens. And it's just this one card. I have several other 8gb cards that work fine but those don't hold much HD footage. It's really frustrating. I'm recording 1080p/24fps on a T4i.

Any ideas what would cause this to happen? Also, what cards do you use to record HD video and do you like them?
 
I use Sandisk too, they are great! I've like 5 of them (16GB)
Hadn't any issues like that with mine.

The wee gold chips on the end could be damaged. See if they're damaged. Or it could be a faulty card, just take it back to where you bought it from.
 
Yeah it sounds like you got a lemon. For my T3i I've used a scandisk class 10 and it's never had an issue.
Check the card when you pop it out too, see if it's really hot or not. If it's overheating after a few minutes you might want to get your camera checked out too.
 
I had similar issues with one of my old Sandisk SDHC cards but it wasn't a class 10, I was trying to use it in the 650D and it would record for around 30 seconds. I use a Kingston 64GB SDXC myself now and it works flawlessy. It sounds like a card issue to me though, if you have tried a low level format I dont think theres anything you can do other than replace it.
 
Thanks for the advice guys! This helps a lot. Yeah, I'm definitely going to have to look into this a bit more and get to the bottom of it. I'm thinking there's just something wrong with this card. Like I said, it doesn't seem to be happening with my other ones.
 
Hey there, this sounds like a strange issue.

As others said it might be a physical problem or as we all know production companies cant make 100% perfect items so you might as well consider that you just got a faulty cards.
But it might be something else, as I discovered the following :
I have a phone that came with a 8Gb microSDHC ( no manufacturer name on it ) but even before I got it I invested in a supposedly better microSDHC I think it was a Sandisk class 10 same size 8Gb, then I finally got the phone and got some testing tools, just to find out that the card that come with the phone which is totally no name and is supposed to be class 8 is faster than the one I bought as class 10. So I think you might as well go ahead and if you can run some speed tests to see if it's fast enough for real, since lack of speed may do this as the recorder's buffer fills up and at the same time it's unable to write it out since the card is too slow.

Also keep in mind that card speeds are not symmetrical, class 10 is only the read speed, for many cards write speed stays undefined. I know its a class, but still they tend to over-enhance the truth by saying it's class 10 while it's write speed is almost class 10.
My experience is that cheap cards go near ratio of 2:1 ( reading / writing speed ) and expensive cards are nearly 1:1, they write as fast as they read.
A real-life example I can give you is a stat form my phone : Sandisk class ?? microSDHC - read speed 4.5 Mb/s | write speed 4.5 Mb/s

So yes it should work for you , the problem is that as you say, it doesn't work :D

Awesome! Thanks. There's some really good information here. Yeah, I'm definitely going to do a speed test and compare it to my 8gb card that works fine, and that should give me a good picture of where the issue is coming from!
 
A class 10 is more then enough for HD video recording with most cameras. However, there are a LOT of fake Sandisk cards in circulation at the moment. They are very hard to spot since they are such a good replica. Even some large retailers, like Amazon, sometimes unknowingly have fake cards! You could possibly have a lower speed fake card in your hands!

If you Google 'How to spot a fake Sandisk SD Card' you should get plenty of results with how to spot a fake. ;)
