Solved my problem using memory card on mobile (Pantech Burst)
However when I tried to use this micro SD card with my new Pantech Burst mobile phone, it started giving message that SD card is damaged. Then I checked it with my PC, old mobile and it was working. Now I am little confused an checked again with Pantech Burst and it showed again SD card damaged and asked me to try formatting the card.
So I took the backup of the card, and then choose format from the phone. However after formatting also, it gave the same error. Now I thought it is because of the card incompatibility with phone. But when I put the card back to PC, I found it formatted.
Now how does the card got formatted, if it is not compatible to my phone? I did some research and found the problem.
Now these are the magic steps which made my micro SD card working with my mobile phone.
