EDIT: Ok, so the answer was yes, it was actually that easy and nothing is messed up. I still feel like that was way too easy.
So long story short, I have a new HDD(3TB), and I want to put it in my case. I'm pretty sure that I know what to do, but it feels too easy.
Currently my setup is as follows:
C: - SSD which basically has the boot data, a couple of programs, and that's all. - 750GB which really acts as the main drive(most programs are installed on it, most data that I work with is installed on it, etc.) This one's getting full.
E: - 750 GB which is basically my media/backup drive, and some programs have been being thrown there since D's almost full. This drive is... well it certainly isn't empty.
I would like to change it to the following:
C: - Unchanged - 3TB main drive
E/F: 750GB Media/Backup.
The only rub I have is that I'm currently unable to mount all my drives(my case has some special mounting screws for it's drive bay, and I can't find my spares, and I don't know if/when I can order replacement parts, since I haven't heard back from them yet and there's no easy way).
So what I'd like to do for now is just clone over my D drive to the 3 TB, remove the D drive, and then when/if I can mount it back, put it in, format, everything works out. And for the time being just have D be totally swapped with the old D sitting in wait until I can pop it back in, format it, and use it like new.
As far as I can tell, this should be as easy as:
1: With the 3TB somewhere(say, lying on the floor of the case for now), plug it into the Motherboard.
2: Use some HDD cloning tool(Is clonezilla still good? Or EaseUS?) to clone the old D drive to the new HDD. Then turn off the computer when done.
3: Physically remove the old D drive, and plop in the new one, put the old one somewhere safe so it can wait until it has a purpose in life again
4: Turn back on the computer and my D drive will now just work like before but with 2.25 TB more free.
This seems like crazy and like it shouldn't work, since I have programs installed and it seems like they shouldn't just be able to find themselves on a new HDD with stuff just copied over. Is there something I'm missing or something else I'd need to do, or is this crazy in general, or would this actually work as easily as it seems? Also do I still need to get some cloning tool, or is there a native way to do this in Win10 now?
