I will be sending my card in to a data recovery firm sometime in the next week and will post the results once i get them
I now have a response from a data recovery firm and this what thay discovered
Our lab has completed the evaluation and the card was found to have severe firmware corruption. The memory chip in this card is a monolithic technology which makes recovery highly complex (may be even temporarily unrecoverable).
We will need to do whatever is required to try to get a read from the memory card. If we regain access to the data, we will do a logical reassembly to try to put the files and directories back together to get them as close as possible to their original state. At the end of the process, we will provide you with a file list to review so you can approve the completion of work.
The cost of the recovery will be $950 and the estimated time to complete your case is 9 business days.

The same advice is still relevant.

Ok i agree... but in this case we'll have to change the advice a little bit..:
"Backup every time you save something to your card "
It failed after only 4 days of use and that's the problem.. ppl use the card for a few hours an then it fails.. we can't back it up every time we use it! that's nonsense..

I have the same issues. I have a car camera and keep wondering why one day it says it's recording, the next it's not. I put the 64G Micro SD into my mac and try to erase it. It says it does, and I can try to trash files too, and I empty the trash. Then I unmount it and remount it and the files are still there. So yeah, controller is not working or memory is stuck or whatever. Regardless, I'm sure a lot of people bought these like I did because they were on sale. But they're junk. I'm switching Micro SD companies and never coming back. When you don't test your products, or sell junk that doesn't work, you lose customers for life.

Bought tthe Sandisk Ultra 64 GB card for a trip I'm now on. in brand new Gopro Hero3 and after two days failed completely. GoPro can't even read the disc when inserted (says NO SD). I will return card for replacement or refund when back from vacation). Am flabbergasted that so many problems with this product have already been filed. What is SanDisk's response?
Unfortunately this product is "ultra" inferior.

gopro released a firmware update yesterday. Anyone experiencing these types of issues should probably update their gopro firmware. It may prevent some of these types of issues.

Same situation happened to me!
I ordered another card today, but after finding this forum, thinking of cancelling order and purchasing a different brand.
Contacted SanDisk about returning my defective card, see what they will do for me.
The first time my card went defective I was able to reformat. Now my computers wont even recognise I have inserted it. when trying to reformat while it is inside camera both of my computers state Windows cannot format.
Thought about buying 32 GB cards, the forums tell me theese also have similar problems!
