recently i put songs into my memory card by connecting to my pc .later when inserted it into my phone (samsang corby) it did not recognise and even my pc also dint recognise...wat might be the problem ?is it due to virus?
 
Hi vamshi
what I you to do go into device manager and look under USB then put in your memory card to see if it shows up in the device manager.

Then go into my computer and see if it shows up there.
