I have this 2gb micro-sd transcend card that no longer works on my phone. I tried formatting it on my Windows 7 Toshiba laptop.And another thing, I don't see any security lock on the side's.Every time I hook it up on the laptop..it says Windows needs to Format it. I clicked on format and then another pop up message appears saying.."Windows was unable to complete the Format. Now what could be the problem..is my micro-sd card bad?
If the card is on the older side, I would say that it probably malfunctioned to the point where it's not even worth trying to mess with it. You can head to newegg or walmart or something and get another for cheap.
