Sandisk 16gb SD card is freezing my camera and computer why?

I have a sandisk 16gb SD card which I use in my Nikon D5100. I was using my camera for filming which I hadn't done before, the video was approx 10 mins long. My camera screen went blank during the end of this with a yellow egg timer. This remained and I was unable to switch my camera of and in the end had to take the battery out.
After trying to turn it off and on a again and leaving the camera running a message came up saying that the sd card was not working, I tried putting it into my laptop but my laptop froze, I was unable to access the information from the SD card or connect to the internet or open anything at all even the task manager to shut down anything unresponsive. When I removed the SD card the laptop worked fine and the Camera seems fine, although I don't have a spare SD card to try and take photos with.
I was just wondering what the problem might be and if there would be anyway of recovering the photos on the SD card without downloading or using any over software. Its not the end of the world if I can't, I wouldn't want to spend any money on recovering them but if there's a way it would be great to try!

The SD card is toast. You don't want to try to recover the data on it. Replace it.

Hi

As Awffy Huffy states it sound like you borked your SD card.

You recorded a long video which took its time to be written to the SD card (probably of the wrong class too), you pulled the battery from the camera whilst it was writing the data, what did you expect?

The problems you encounter when you plug it into your laptop is indicative of a read error, your laptop is constantly polling the SD Card trying to read it but getting no reply so pours all its resources into it (hence the lock up). Pulling the card out stops this and returns it to normal.

My best advice would be to bin it and get a new one of a faster class such as this one: http://www.wexphotographic.com/buy-sandisk-16gb-extreme-pro-95mb-sec-sdhc-card/p1527814

Sandisk make SD Cards at different speeds and therefore different price points:

If you have £280 burning in your pocket you could go for this Sandisk Class U3 Card: http://www.wexphotographic.com/buy-sandisk-64gb-extreme-pro-280mb-s-sdxc-uhs-ii/p1549305

You need a faster SD card. Look for a Class 10 card (A "C" with a 10 inside it).

At the first sign of error, throw the memory card away and replace with a new one. Format the new one before using.
