However, a differing charge in the drive will have an interaction with anything magnetic around it, making its observed weight different without the mass changing.

Well, if the distance between the platter and the centre of the earth changes, the weight will change.

so what ended up being the over all answer to this?

by technicality the HDD Gains a Little Weight, in an incredibly small sense

but then the moving mechanism themselves shave off particles over time losing weight in an incredibly small sense?

Meaning, that more than likely, the HDD Ends up weighing the same no matter what?

At this point, the questions cannot be answered? Because if it loses particles, and weight due to the mechanism itself working, then the variable of how long the drive has been in use would then determine how much weight it lost vs gained ?

Im stupid confused

No such thing as a "more charged" electron. The electron itself is the charge (bit simplified, but for this argument it holds true). While electrons can have different states of energy, they are always charged with -1. So an SSD would have extra electrons.
Also, E=MC², as you mentioned later on, states that energy have mass. Though this is an oversimplified version of the truth. Photons have mass, so light has mass. Heat is just molecules moving.
Wikipedia is probably the most accurate information source out there. Sure, anyone can change it, but that doesn't make it inaccurate. If you change an article, exactly what you changed and the stated reason why is easily accesible, so filtrating away inaccurate information is simple. Most people editing articles on physics (read: all people) only do so when they know they are correct. Sources are allways given, so if you have any doubts regarding the subject, just check it's sources. If someone made a bad or incorrect edit, every single previous edit of the page is available for reading.
Wikipedia is also better than most other media, such as physics books becouse it is constantly updated, gives sources and directs you to relevant related information.
The question at hand has already been answered so I won't bother with an input, but I will thank all the answers; I learned something new.

I don't deny that Wikipedia can be exceedingly accurate, but I have to other experience out-side of that. Can you cite Wikipedia when submitting research papers in college (honest question, never been to college)?

You cite the sources that Wikipedia lists.

A HDD enclosure is vacuumed shut upon factory, which is more relevant than a one that is not in this discussion.

And also to 1 rep-wiki scholars, law of conservation of mass is not in any form dependent upon a closed system. thumb.gif
(i.e. burning a match does not equate to net loss weight but merely the carbon mass is dissipated through the atmosphere and heat.)
