Dear All,

Yesterday I bought a Sandisk Extreme 16GB CF card. When checking the memory space on the computer, noticed it read :

Used space : 8 KB
Free space : 14.8 GB

What happened to the other memory space? Is this normal?

Thanks for reading.

Normal.

Even when you buy hard drives, same thing. E.g., if you take a 500GB drive, completely brand new from a shop and plug it in, you will see that the free space is less than 500GB.

Don't worry and enjoy taking more photos. :)

In Decimal system 1 GB =1,000,000,000 Byte

In Binary system 1GB=1,073,741,824 Byte.

If you multiply 14.8X1.074, you'll get close to 16GB.

You're not getting anything less but it's because computers uses binary system to count :)

As above, your computer "counts" 1 Gb as 1 000 000 000 bytes instead of 1 024 000 000 bytes so on every kilobyte level you "lose 2.4%", on megabyte level you "lose" 4.8% while on gigabyte level you "lose" 7.2% :)
