First, you have set a password for the memory card of your Nokia phone. Obviously you did it for the purpose of securing data stored in that card. Then one day, you forgot your password or out of nothing the memory card became inaccessible. What will you do? Panic? You don't have to. Don't recall all passwords that are jumbling on your mind either. The easiest thing to do (that many mobile phone users don't know) is to rename the memory card. Surprisingly simple isn't it? But how do you rename your memory card? Here: 1. Go to the mobile phone Menu/Gallery and then scroll down to the memory card. Just highlight it, do not open yet. 2. Instead, go to Options/ Rename memory card, enter Select. 3. Delete the old name by pressing Clear several times until the entry is clear. 4. Now, type your desired new memory card name and press OK. That's it, you can access the memory card again! Note: This procedure has been done on a Nokia 6300, which is a S40 series phone, with a MicroSD Memory Card. It's up to you to try this with other phone models. Goodluck!
