What's the security code of my SD?


Hi Karla! What kind of cellphone do you have? It's most likely asking for your phone's security code and not your microSD. If it's a Nokia phone, 12345 should work. You could also try 00000 or 0000. If that doesn't work, just post the make and model and we'll figure it out.

External memory card for LG kc550 won't work


I was also getting bad format error on my LG kc550. Did a little research (read the instruction book) and if you want to properly format your card to work with the phone you must insert the card into the phone then connect the phone to your computer via the USB cable supplied. Go to "My Computer" and you should see that the phone and memory card are displayed as two separate external devices, when you try to access the memory card your computer should ask you to format it. Click Ok and a Format box will come up, click Ok again and your computer will format the memory card acordingly.

Unfortunatly this resulted in my losing 4gb of space on the card, i dont know wether its based on percentage or a fixed amount the phone needs but if thats the case you will need more than 4GB for your card to be formated for your phone
