Windows 7: hard drive sizing rort

hard drive sizing rort

I don't know about you guys, but I build computers pretty frequently, and it really irritates me that consumers do not get what they pay for with regards to HDDs and their capacity.
I remember working for years to build my first PC - and the HDD was 320gb, and I was super excited. Although, on completing construction of this monster of the day, I realised the capacity of my HDD was in fact closer to 299gb, and I wondered... Why?
I made some calls and did some reading and I did not like what I found.
We all know (or should know) that computers are built on binary data (1s and 0s) that are organised into bits (single data) and bytes (8 data), and that octal's equivalent grouping of the decimal 1000 is 1024. Thats why a kilobyte is 1024 bytes, a megabyte is 1024 kilobytes etc.
So a 2TB HDD, in theory, should be 2048GB, right? Well... no.
Manufacturers produce HDDs on a decimal scale. KB, MB, GB and TB are made and advertised, by manufacturers, as units of 1000.
Computers continue to (And will always) group bytes in units of 1024, which means the end consumer pays for what they're not getting.
As HDDs get bigger, the difference becomes more noticable.
My 2TB HDD is, in fact, showing up in windows as 1.81TB.

So my question is, why do manufacturers get to advertise for what they're not giving you? Why is a 1.81TB HDD not advertised as such, and why is nobody doing anything about it?

Here is the USA, traditional glass CRT type TV sets and video monitors were always sold with larger size specs than they were. It was quite funny to see a box for a TV that said is was 27" in the USA and 25" in Canada. That's right, the same TV was two different sizes in the two adjacent countries. Marketeers are always out to decieve the public into thinking they are getting more than they are actually getting. It doesn't seem to matter how angry people like you may get, they just want to make that sale and the next business quarter be damned! Again, here is Southern California, gasoline is sold by the gallon. Fuel pumps are calibrated and certified by the State of California to be accurrate within a tight tolerance. However, that calibration is for when it's cool outside, which it usually isn't. So the gasoline expands and we pay more for the equivelant energy than it says on the pump, except those few days a year when it's been cold for a while. Welcome to the real world! They are the preditors and we are the prey. Your only defense is to be well informed and try to make enough money that you can live well in spite of them.

Bye.

Right on target. Let the buyer beware. Good post.

so technically, by using a decimal prefix they are, in fact, giving you what you've paid for?

what a crock.

i wonder if we'll ever get a manufacturer that adopts binary designations. i would happily pay extra to someone that plays the game honestly.

Are you for real? is it going to make all that much of a difference, we now talk in TB, thats a lot of bytes.

yes, i am for real.
for a 2TB HDD, i get 1.81 that i can use. thats 190GB. i have 128gb SSD.
you do realise i'm missing more than an entire HDD?
its no small matter - thats 10% missing. if you buy 10kg of rice, would you be happy if you only got 9? or if you bought a box of 12 cokes and you get 10 and a 3/4 bottle.
you'd take it back to the shop, right?
dont see how this is any different. i'm paying for what i'm not getting.

Well, you should complain directly to the manufacturer for not using the same unit conversion as the rest of the computer industry. Isn't there a consumer protection or something for these kind of issues?
