Default Kingston CF Elite pro 133x 16GB - exact byte capacity

I was experiencing some trouble formatting this card. Finally it seems I did it but I wanted to check if it is fomatted to the correct size. In order to do so I searched for the specifications but couldn't find this data.

I was wondering if someone that pocess this card can tell me the "bytes of TOTAL disk space".

The exact card model I have is CF/16GB-S2.

Every manufacturer's 16GB card will be different, and it's unlikely that any two 16GB cards will have the exact same capacity or free space.

First, different manufacturers put different amounts of memory in their cards that can't be used normally, but are only used to fill in for failed memory locations when that happens.

Second, different cameras are likely to format cards with slightly different settings and slightly different configurations, so even if all went well, you'll probably see some difference in the byte count.

Third, storage device manufacturers count kilobytes, megabytes and gigabytes, differently than operating systems in computers and cameras. To the manufacturer of your card, a kilobyte is 1,000 bytes, a megabyte is 1,000,000 bytes, and a gigabyte is 1,000,000,000. But your computer and camera use binary numbers to count, so everything is a power of 2. In binary notation, a kilobyte is 2^10, or 1024 bytes, a megabyte is 2^20, or 1,048,576 bytes, and a gigabyte is 2^30, or 1,073,741,824 bytes. So even though 16GB is really 17,179,869,184 bytes, so long as the capacity of your card is at least 16,000,000,000 bytes, the manufacturer has given you what you paid for. (That's the total capacity, not the free space, btw)
