have alook here for explanation of 'lost' space

Some hard drive manufacturers work out the capacity of drives different to your operating system. In Windows 1K is 1024 bytes and 1 Meg is 1,048,576 bytes, but to most hard drive manufacturers 1K is 1000bytes, 1g is 1,000,000bytes. So if you divide 40,000,000 by 1,048,576 you get 38.14 (a loss of 2 gig to me and you).
Also I think a small portion of space is lost in formatting the drive as well but its quite normal. My 120g shows up as 114g and my 40g shows up like yours as 37.2g

Oops, daings posted the answer as i was typing... damn he's quick!!!

thanks people thought i had done something wrong for a minute cleared that one up.

its the boot sector m8 you allways loss when you set them up

my external drive is a 250 but formated down to 233 17gb lost nothing you can do

17gb is not the boot sector

what is it then

see the two above yours

the boot sector is typically 512 bytes i think
