Why does Time Machine report a different amount of space left?

    I understand that time machine doesn't back up certain directories, and so the actual backup size is different, but why does the log say that my drive has 210gb of free space after time machine, but the mounted volume say it has 226gb free?

    I recently deleted my timemachine plist and reformatted my external oak to start time machine fresh.

    Is this a difference between metric an binary counting of bytes?

    Yeah, I did a check - the conversion is pretty close. But why would Snow Leopard switch to Metric but leave other things in binary? For example, iTunes and iPod sizes are still reported in binary.

    I don't mind the metric, in fact, I probably prefer it, but to have both is stupid.
