For get the serial number of all hard drives in my computer, I use:   wmic diskdrive get serialnumber   But, I want to get the serial number of the hard drive where I am working.  I explain: I have 2 hard drives, one of them has 2 partitions C and D. The other has one partition E. With the command line, if I am working in C partition, when I type the wmic command, I want to get only the serial number of the hard drive which has this partition, not the serial of the hard drive with the E partition.  I want to make a license code for my software. you can install the software in any partition. i want the serial number of the hard drive that contains these partition specifycally. the volume serial number of the partition changes when you format, reinstall, etc, but the serial number of the hard drive not. i know there are softwares to change the serial number, but my possible clients are not so smarts.
From the Windows NT-based (Windows XP and 7 specifically) command prompt, how can I get the serial number of a hard drive as a variable? The one I'm looking at is the serial number of the physical hard disk drive
Is there an issue tracker for already reported Mathematica bugs? I read somewhere that companies are not required to pay dividends to shareholders (this is correct, yes?).   If so, then if company A never pays dividends to its shareholders, then what is the point of owning company A's stock? Surely the right to one vote for company A's Board can't be that valuable.   What is it that I'm missing? Derivative of function with 2 variables I've leart in Calculus 1 that the derivetive of $f(x)$ is:  $$\lim_{h\to0} \frac{f(x+h) - f(x)}{h}$$.  suppose $f(x,y)$ is a function with 2 variables,  does $$f'(x,y) = \lim_{h\to0} \frac{f(x+h, y+h) - f(x,y)}{h}$$ ?  If not , what is the derivetive of function with 2 variables? Undergraduate/High-School-Olympiad Level Introductory Number Theory Books For Self-Learning Aliens abduct mathematician, astronomer, woman Bits I remember about this SF movie which probably originated in late 50s / early 60s:   Humans are flying in a light, general aviation, high winged, single engine aircraft. An alien in a flying saucer abducts the whole kit &amp; kaboodle (plane &amp; passengers). Takes them to a secret terrestrial base Eventually tells them that his computer is damaged and he needs their help to get back to his planet. He needs an astronomer for planetary masses &amp; other information. He needs a mathematician to calculate trajectories and perform other calculations. He needs the woman as eye candy, lol They eventually make it back to the alien home planet which is under attack by its enemy. The attacking aliens are bombarding the original alien's home planet with meteors / asteroids.   That's about all I remember. Why is the Apps flash storage so high and how can it be reduced?

Edit: I had tried all the suggestions made by @user3439894 in his answer but didn't mention it before posting. What is "cloning a hard drive" and how does one go about doing it? What does cloning a hard drive mean? Is it just simply copying over all the "CONTENT" of the hard drive EXCLUDING the operating system, drivers, all the installed programs? or is it copying the ENTIRE hard drive BIT for BIT? Is the cloned hard drive bootable?  I have an external USB hard drive and trying to make a exact copy of my computer system by cloning, so that I can connect the cloned hard drive to another machine and boot into it, or install the cloned disk on another computer system and boot into it. Is this possible? Or am I going about this totally wrong?  What is ghosting a hard drive? An example of a group such that $G \cong G \times G$ I was trying to find an example such that $G \cong G \times G$, but I am not getting anywhere. Obviously no finite group satisfies it. What is such group? is one of those surprisingly clear results of mathematical calculations, for which I am inclined to think that some kind of intuitive understanding should or must be possible. However I don't know of any, do you?  *Independence of time $\leftrightarrow$ energy conservation. *Independence of position $\leftrightarrow$ momentum conservation. *Independence of direction $\leftrightarrow$ angular momentum conservation.  I know that the mathematics leads in the direction of Lie-algebra and such but I would like to discuss whether this theorem can be understood from a non-mathematical point of view also.

Out of Bag Error makes CV unnecessary in Random Forests? What does Superman do with his regular clothes after changing in the phone booth? We all know that Superman changes in the phone booth. But where does he put his regular clothes while he's on a mission? He doesn't throw it out, because he changes back. But we don't see him carrying a bag of dirty laundry while he's on a mission.  ("In his right hand, Superman has Lois Lane, and in his left hand he seems to be holding... boxers??)  And I can't imagine he leaves it in the phone booth.  So where does Superman leave his regular clothes after he changes? $\gcd(a,b,c)=\gcd(\gcd(a,b),c)\,$ [GCD Associative Law] Turning fullscreen on made Minecraft crash, and now it crashes on start every time I switched to full screen on minecraft, the screen turned black as if it were loading it took a while so i closed minecraft and reopened it.

Why is $1^{\infty}$ considered to be an indeterminate form From : In calculus and other branches of mathematical analysis, an indeterminate form is an algebraic expression obtained in the context of limits. Limits involving algebraic operations are often performed by replacing subexpressions by their limits; if the expression obtained after this substitution does not give enough information to determine the original limit, it is known as an indeterminate form.    The indeterminate forms include $0^{0},\frac{0}{0},(\infty - \infty),1^{\infty}, \ \text{etc}\cdots$   My question is can anyone give me a nice explanation of why $1^{\infty}$ is considered to be an indeterminate form? Because, i don't see any justification of this fact. I am still perplexed. Do Skyrim mods work with the Special Edition? I typically play Skyrim with a number of mods installed, and while I'm excited to try the Special Edition, there are a few mods that I'd much rather not play without.  Can I install mods built for the normal Skyrim game with the Special Edition, or do I have to wait until mod authors write new versions before I can play with those mods? iOS app blocking actions with "you must join this site" message for sites I belong to How do I set an environment variable on the command line and have it appear in commands?
