For past few hours i've been grappling with this strange problem with my notebook - compaq v2317 notebook (windows xp home sp2), with a Texas Instruments built-in multiple card reader.
My 1gb sd card which is working fine in my camera and which used to work fine on the notebook till sometime back is not being read properly by it now. Though it is recognised by windows but when i try to open it, i get a message saying "disk in drive g is not formatted". the card is formatted fine and was working till recently. And when i try to format it i get the message " disk is write protected", then the formatting fails everytime (though the card is not locked). this also ruins the card's existing formatting and then i have to format it in the camera.
I tried another brand new 2gb sd card - and this one is not even showing up in windows. But the strangest this is that my 1gb sony memory stick micro M2 works just fine with its adapter! The problem seems to be only with sd cards. I really don't know what to do. Can anyone please help...
