USB memory keys - 2GB hold 2GB

I've bought several USB keys on Ebay recently.

(USB memory sticks in the shape of a key and under 3mm thick)

Their capacity shows up as slightly greater than their stated or
expected capacity:

- a 2GB key shows up as 2.1GB

After reformatting them I'm getting a more normal figure of 1.88GB for
the 2GB keys, however I did try filling one with data and it did seem
able to write and read a full 2GB - puzzling.

Can anyone shed any light on this?

Did you try reading back the data ... to ensure it was all copied??

Yes - it wrote it back to the HD fine.

 

Oh, o.k., but then when you re-formatted it, it was only 1.8'ish GB! So
why re-format??
