How to delete everything on sd card

[Help pls 64]

I use a Samsung Galaxy Core 2. Please help as fast as possible not being able to use your sd card at all sucks ( i do have space on the sd card and the format sd card option on the phone doesn't work)

If your PC or laptop has a SD Card slot, buy a carrier the size of that slot to house the much smaller Micro SD Card your phone uses. Remove that small card and put it into the carrier then out that into the laptop and do whatever you want to.

If you format it, choose the FAT option. NTFS is for Windows systems and isn't ideal in Android systems.
