Hi there, the raw capacity might be 512mb but understand that to format it requires the use of some space.

There is no way of 'expanding' it. Think of it like a 400 litre fridge - you wont actually get 400 litres of anything in there, because of the shelves that are required - they take up space before you even started.

This is completely normal.

There is another reason

Companies who make data storage devices ie hard drives, flash cars etc consider 1Mb to be 1,000,000 bytes, but companies like microsoft and others who make software consider 1Mb to be 1,048,676 bytes by reasoning that a kilobytes is 1024 bytes and a megabyte is 1024 kilobytes, so when those to systems come into conflict, like your software reading your card it decides that by using its system there is actually less capacity than you are made to believe

I was quite surprised when I read they'd actually created a new term for it aswell.

Mebibyte vs. Megabyte.

http://en.wikipedia.org/wiki/Mebibyte
http://en.wikipedia.org/wiki/Megabyte

The Megabyte entry has a rundown of common usage including the 1000x1000 and 1024x1024 usage.

I wouldn't be too worried about loosing a few megs as a result on a 512. It gets to be a bit more fun when you have a 200GB drive that's actually 186.31GiB.

Mebibyte?? Thats a new one to me having used binary for quite some time. I always found it annoying that there are the two ways of calculating data capacity....feel like im being ripped off

while we're here...

Flashcards.co.nz is selling some 133x SD card but they stated that it is not compatible with imate Jam.

my question is though, what are the max limits that Imate smartphone, Jam, JasJar can take?

I'm interested to get that 133x 2GB SD card and i will be getting JasJar when it is out. but in the meantime I am using smartphone2... so will i be safe to get this 133x SD and use it with my current phone and later with JasJar?

Internet is my backyard...
