Question Advice on large storage drive, and backups needed

Yep, works.

Right click the Unallocated space.
New Simple Volume, Format, give it a drive letter.

Don't think I changed any "options", just chose "simple volume" and the disk number was "2", and just chose a drive letter.

I like that I can resize the images posted here. Are users able to click to enlarge or view in full size if I size them smaller to take up less page/post space?

Thanks for your help, sir.

Looks good.
And yes, the resize YOU did has no bearing on the actual image size.

Finally got started on copying the old drive data to new drive. I planned on doing "chunks" of 500GB or less. I first did just under 200GB, I think. I came back to one of those "path name too long" annoying messages, so it was waiting for me to click that to move on. I hate that. Fortunately, it was on the last file I think. And finished right after I got rid of that message.

I installed crystaldiskinfo, cool program. Anyway, after another, but ~400GB sized transfer, I did a couple ~700GB.
The ambient room temp. is ~25-26*C. When I checked the drive temp. in CDI, I think it first said...39*C maybe. I've checked several times now, while doing a bigger transfer, it doesn't really seem get above 37*-39*. I was thinking heat would be a problem, but it doesn't look like it. I have a nice...120mm Noctua fan behind the two drives, on an adjustable 12v adapter, pushing air over them (and likely "into" the rear of the Maiwo enclosure.
The Maiwo has pretty annoying led light(s) on the "front" of the enclosure. Solid, bright red when powered on. With a bright blue, rapidly blinking light in the center of the solid red light when there's any data being transferred. I guess that could be the "back"; the power in and usb-to-pc connections are here, but so are the two usb "hub" ports - and a "power" on/off button (which I'm afraid to actually use, for some reason).

I've got about 1.5tb left to copy. Might do some more tonight.

Anyways. Thanks for the help everyone. I hope the enclosure lasts long enough to at least get this task done. I might replace it with a Startech, or there's an iCan enclosure available too. Has anyone heard of iCan? I was looking just for "brands" of enclosure with more reputable, or at least industry "known" names.

Thanks again.

I have a drive that stores a bunch of folders/files, Drive A. I had copied all of that data to the new drive, Drive B. But now I have changed some things on Drive A (a few new files and folders, and maybe organized a couple files into a (new) folder. How do I get *all* files and folders on one drive (or both drives) to be the same now, without losing any of them and without having a bunch of duplicates, (and without taking 3 days because it's...re-writing every single file including all the ones that are already present.

Note: There might even be a file/folder on Drive B that I added that isn't on Drive A.

[With another folder, with smaller files, I managed to copy the folder (or files in it, can't remember) and "pasted" it to the corresponding containing folder (or in the actual corresponding folder, again - can't remember) on the Drive B. And it seems to have "worked" in that it gave me the option to skip duplicates, essentially.
When I tried on the next folder area I knew I'd changed/added to, I didn't see that option, and I don't know if it's just because there's much more data than the first operation I did (it's around 3TB). Maybe it has to fully calculate first, or encounter a duplicate or something first, before it will give that option.
I don't want to mess something up!
