My New "2" GB MicroSD card
 
I just put my new SanDisk 2 GB microSD card into my Curve and it says I only have 1.8 GB free on my media card. Does SanDisk just round up to get the 2?

Is there anything I can do to increase free space?

The difference is due to a Binary vs Decimal conversion.
There's nothing wrong with your card. 1.8GB is correct.

Your 2GB SD card is actually 2 billion bytes.
2 billion bytes (2,000,000,000) is reported as 1.8GB because a binary gigabye is not exactly 1,000,000,000 bytes. It's 1024 x 1024 x 1024 bytes, which equals 1,073,741,824.

2,000,000,000 / 1,073,741,824 = 1.8

Awesome job there with the explanation.

no Shyt, that leaves nothing to question right there. Although BetterOff's response is more amusing to say the least

Good explanation but you also forgot one thing.

Some space are being used up when the card is formated and ready to be used. So there's already some data on the card.

True, however the space used by formatting is neglible compared to the 7% capacity "loss" due to binary conversion.

It's doubtful you'd even notice it, so I didn't think it necessary to even mention it.
