I was attempting to write a new SD Card for my Raspberry Pi and got an error. I instantly thought it was the SD Card that failed, however further testing with a different SD Card today results in the device never showing up.
Looks like the SD Card reader has died. The model I have been using is the same one here from the same ebay seller. Not sure its got a warranty, but will soon find out, as I asked.
In the meantime, found a different model from China for $1 delivered. So ordered 2 and will keep a spare.
I guess I can write the SD Card tonight using a digital camera that takes SD Cards, which I do have access too.
Still a bit annoying to say the least.
