Hey guys, my SD card (~16 Gigs when bought) only shows 3.73 Gb when I put it in my computer. Before you ask, yes I checked Disk Management and it says that there are no partitions on the SD card other than the 3.73 Gb one. Also yes, it did have 16-ish Gb when I bought it. I don't know what could've happened when I "lost" 12.3 something Gigs. Any and all help would be appreciated. Thanks.
