When you format a disk, it loses space.

1.44mb floppy disks are formatted to 1.38mb.

My 160gb hard drive is formatted to 149gb space.

Just how it is =)

This may explain it for you: http://articles.networktechs.com/36-p1.php

Most operating systems define a hard disk drives capacity using binary or base-2 mathematics. This translates to 1 gigabyte (GB) equal to 1,073,741,824 bytes. This is the correct value when using binary or base-2 mathematics.

However, hard disk drive manufacturers define drive sizes using base-10 mathematics, in which 1 GB is equal to 1,000,000,000 bytes (rather than the 1,073,741,824 bytes, as listed above).

This discrepancy in reporting drive sizes (base-2 vs. base-10) may lead you to believe that you have a hard disk drive of less than expected capacity if you compare the figure reported by the operating system with the figure reported by your documentation, although the actual hard drive size is identical. Microsoft Windows simply counts the size differently, and will report a different, slightly smaller, figure.

too quick for me Rafy ;)

yes, that is why, its nothing todo with formatting.
the hard disk manufacturers use a decimal rather than binary system so they define ONE gigabyte as ONE billion bytes. in practise, ONE gigabyte is actually (1024)^3.

haha i never knew why, i always thought its just something that is, like something to do with how you format it. i never suspected they use different systems

i always use the ...dunno what you call it, the system where 1024Gb is a terrabyte, not the 1000Gb is a terrabyte system

i always thought thats what everyone uses... sneaky buggers

ahh ok. I did SDD Option topic 2, so i know what Rafy is talking about, but it never dawned on me that that would be the problem.

Sneaky buggers.. I want 300 GB of space because thats what i payed for :(

(Not that i will ever use that much space).
