Reasoning: Energy =^ Mass. Entropy being reduced.

Come to think of it: Does it maybe get lighter? As entropy is reduced (depending on the initial state of the disk)

The material of the drive remains the same, and the energy of the drive remains the same, so the mass does not increase. The entropy idea is actually incorrect because the bits of data are no more or less entropic when written. The perceived order is just that- perceived. It depends on the machinery or software that interprets it.

Nope, the orientation of the magnetic particles are changed but they are neither added nor removed, so mass remains the same.
Entropy does not really enter into it - when a drive is formatted all the bits are arranged to "zero", so entropy (as it refers to the orientation of groups of the magnetic particles) is already minimized at the beginning.
If you want to call entropy the breaking up of a string of "zeros" by adding in "ones" then, yes, the entropy will increase as data is added.

No. Entropy does not apply here. There is no difference in energy between the two magnetic states of one bit on a disc, so no change in weight.

No, the only change being made on the hard disk is that the magnetic charge has been changed, nothing that will affect its mass.

There is possibility for an unnoticeable i.e very small increase in surface area with no change in weight of the hard disk.

data is essentially a postive charge for a 1 and a negative change for a 0, so even if the drive is empty it is already full of data.

No!! It does not get heavier!! That's about like the question: How much does light weigh? DOY!!

wow, no buddy, does your brain get heavier when you learn a new song...
