Even worse, you divided by (110 * 1024) for kilobytes so theres an even bigger 
loss if you divided by (110 * 1000) .....

However, ignoring the use of 'M' or 'm' in megabytes, a *real* megabyte is as I 
have stated above, 1024 * 1024 bytes and a gigabyte is 1024 of those. The *but* 
is that a hard disc sales brochure says that the capacity is 400GB which we 
technically savvy chaps and chapesses assume to be 400 * 1024 * 1024 * 1024 
unfortunately, those savvy sales people know that we think this way - which is 
why they say it. They, on the other hand mean that 400 GB is 400 * 1000 * 1000 
* 1000 bytes - so we lose out by using the correct numbers.

It is, basically, another sales con.

Of course, the capacity decreases when you format the disc as well (how did 
they work out the unformatted capacity, because, if it is unformatted then you 
cannot store anything on it !)


Cheers,
Norman.
