Big question for the scientific ones....

[Ingolstadt]

I was wondering this for sometime now:

Imagine there are two 5000GB hard disk.

1. Totally empty with 5000GB free space

2. Fully loaded with movies pics and whatsoever with no space left.

Will 2 be at least slightly heavier than 1 ??

0's and 1's don't weight anything.

No. The same weight.

How is information stored on the hard drive? How is it written and read exactly?

Taken from Wikipedia:

HDDs record data by magnetizing a magnetic material in a pattern that represents the data. They read the data back by detecting the magnetization of the material.

An arm writes all the information 0101 or a variation of that onto a magnetic disk(s). That's why you can hear spinning if you load a program. That's the sound of the info being accessed.

I actually knew how data was written on HDs. The reason i asked this, is that by magnetizing, they had actually added electrons in it right? So does it weighs differently?

There is no such thing as 'nothing' if you understand me. Hence i asked using a 5000GB HD and 'slightly, even a tad' heavier. Imagine all the movies, pictures and stuffs.... 5000GB of them.... nothing was added? weird.

So.... is it?

Do you know how much an electron weights? Even billions and billions of them wouldn't add anything.

EDIT: 9.109 3826(16) × 10e-31 kg

So it's actually heavier? DATA written on a disc?

You can always enlarge my whole assumption to perhas 10000000000000000000000000000000000000000000000000 0000000GB hard disk

"The entire internet weighs 0.2 millionths of an ounce and although torrent traffic amounts to a massive 12 petabyte, it weighs in at just 0.06 millionths of an ounce."

What is the wight of all the bittorrents in the world?

how much does the internet weigh?

[derekthetree]

i would say no it isn't any heavier. the method used to magnetize the portion of the hard drive doesn't add any electrons, or anything else, to the material
the orientation of the magnetic dipoles will just change

[aiasib]

now that thats solved:


Is a charged battery heavier than an empty battery?

yes, a charged cell (a battery is a battery of cells ) will have more electrons than an uncharged one

[Kultag]

Don't forget E=mc^2. Doesn't the more energy and the moving parts mean higher mass?

[drakkie]

True... We learned on high school the principle.. long ago and far back in memory, i think this was 2nd grade (14 y/o)

Anyway the liquids in the cell react to a kind of thingy in it. In this process they become solid (Redox reaction). I can't remember if there is much difference in weight, but I don't think so. It might be lighter, if you count in the loss of electrons in the process.

Say you have a reaction where 2 electrons leave the molecule, which then sticks to something becoming in the solid state. The 2 electrons leave it and go through your car

Damn how I hated chemistry !!!
