Rockchip tablet - issue with recognizing microSD card

Hi - I got the following Rockchip Android tablet from Amazon;

Amazon.com: 7 Touch Tablet Internet Media Player 2Gb Google Android Os - ROCKCHIP CPU: Computer & Accessories

7 Touch Tablet Internet Media Player 2Gb Google Android Os - ROCKCHIP CPU

Works decently; however after a few days, it does not recognize the microSD card at all :-( Reboots do not help. The config options always says "Unmount SD Card"; the system notifications always say there is no SD card present. I have tried with 2 different versions - a 2GB card and a 8GB card. Both the cards are recognized in my Windows PC and I am able to add/view files in it. When I insert the card back in tablet, its not recognized.

The tablet is virtually useless without this extra SD card storage for me (as internal memory is only 256MB).

I am hoping someone here can help me fix this problem.

Please help!!! Thanks a lot!!!!

have you reformatted the card in your pc and then place in the tablet.
reformat again in the tablet.
see what that does.

my tablet takes a while to read the card , but gets there.
does your tablet not recognise the sd card at all ?

does it read pictures / movies / app's ?????
via your file explorer

I have the same problem, is there any way to fix this? I have tried to reset to factory settings didn't work. It doesn't recognize the sd card. Any suggestions?
