I had a 16GB microsd in my S3

I noticed that each time when putting down the phone, even if it gets the slightest of bumps it displayed a message saying microsd removed unexpectedly and then it would start scanning it again and then redisplay the contents. Its been doing that for quite sometime now.

And since last weekend it says microsd corrupted and unable to read from it

So I took it out and put into its SD Adapter and tried to format it using windows but I cannot even format it.
Quick format or Full / long format, both fail

Has anyone else faced this issue of the microsd ejecting and then remounting when the phone gets a bump..

I will most likely put in another microsd coming weekend.. waiting for some deals on ANZAC Day to get another microsd for my phone.

I have a bad feeling that with the phone doing the eject & remount all the time even a new microsd wont have a long life
