t2i : Card cannot be accessed. Reinsert/change card or format card with camera

This is the SECOND time I've had this problem, this time with a different new 32gb class 6 sd card. Was out taking pictures today and for the second time in the short period I've owned this camera I got a "card cannot be accessed reinsert/change the card or format with camera" after about 150 shots. The first time this happened (with the other card) there was nothing I could do, nothing (pc or camera) was able to format the card and I had to return it- microcenter refunded me (though I never tried recovery tools). I bought another, more expensive card and now it happened again. Both were 32GB class 6 cards. I'm in the process of trying to use photorec to recover the files and it looks like it will work(still processing). Bottom line is if this is a "feature" of this camera what is Canon doing about it? Anyone else have this problem?

I had this exact same problem with my T2i last weekend!
Looks like i'm not the only one with this issue.
I'm really beginning to think this is going to become a problem with many people.

here is the Thread I started about the same issue https://photography-on-the.net/forum/showthre​ad.php?t=949486

Cameras don't have the ability to screw up flash based memory from a file system perspective, so why would you think it is automatically 100% the cameras fault? In fact, there are so many things than can and do go wrong with SDHC cards I would almost always think the card is bad.

I suspect you got 2 bad cards as unlikely as that may seem. For example, A Data is known for having a high failure rate.

seems odd to have 2 identical problems in such a short period of use with different cards. I was able to recover the files with photorec on a PC and was able to do a low level format with the camera on this latest sd card. We'll see if it happens again. I suspect many of these cards are made by the same manufacturer and just have different labels on them, and very different prices for the same exact card with different labels...

yes I think it seems odd to have that often as well

I would think that if a camera is able to DO a low level format on a card, then it could just as easily screw up that formatting if something went wrong...

What cards are you using ?

initial one was a microcenter house brand around $70, this one is transcend, around $90.

I had this problem- subsequently realizing that there is a lock feature on SD cards, like on floppy disks. might this be the problem?

thats not the problem. Took some more photos yesterday with no problem so far...
