how come my 512 memory card only has 442 mega bites

if i format it will it say it has 512mb?

no... thats how digital media stoage works... it has worked this way since the inception of digital stoage media about 4 decades ago, welcome to the club.

wow that's a rip off i didnt get what i paid fornerozero25

yes you did... in order to format storage space to prepare for data it has to organize the sectors, doing so causes memory to be unusable for saving. Like I said, EVERY SINGLE form of storage since the begninng of computers works this way. It always amazes me when people are surprised by this.... is this the first time you have used a computer? It's kinda common knowledge by now.

Memory cards never have the full amount advertised of actual usable space. It's normal.gamerfreak13

Doesn't that have to do with how manufacturers recognize memory size (1000 bytes per kilobyte, 1000 kilobytes per megabyte, etc.) compared to how computers recognize memory size (1024 bytes per kilobyte, 1024 kilobytes per megabyte, etc.)? My 80 GB hard drive for example is recognized as 74.52 GB by my computer but after calculations, it's around 80 GB.

74.52 GB x 1024 x 1024 x 1024 = 80015240724.48 bytes

80015240724.48 bytes / 1000 /1000 / 1000 = 80.01 GB

no... it's always 1024, sometimes it's just rounded for sake of giving nice rounded numbers... it's impossible to get a number of bytes that is not a power of 2, because of the binary system.
