How to shrink your C drive (add a new partition) Windows 10?

Hello. So I have a new computer. It came with a 1TB HDD. A WDC WD10 if that helps. Anyway, what I'd like to do is split this HDD into two partitions so I have a C: drive (for my OS) and a D: drive (for downloads/storage etc).

Now I know how to do this, I've been reading around on it. I can do it using the Windows 10 Disk Management or even EaseUS which I have. But I'm just asking here first to see if anyone else has done this before I do something drastically wrong! LOL

Basically, I'm at the shrink partition part, and I know that M$ say Windows 10 needs at least 20GB but you should make it larger just in case for installed apps etc etc. So I'd like to set the C: drive partition to 40GB and then the rest as my D: drive partition.

Basically, what size should I put into that field? I know that 1GB = 1000 MB. So if I wanted a C: drive partition that was 40GB I would enter 40000 there, right? And from there on I can format it with NTFS etc and voila! I have my C: and D: drive.

Right?

Anyone know about this stuff or has done it before?

Is my query right? Is that what I need to do for to make this happen like that?

Thanks in advance.

Mike.

I had the exact same issue when I first got my computer. For some reason, it had 90% of space on disk C and the 10% on D. I use it same as you. C for all the program installs and D for my downloads and games so I was pretty frustrated.

I decided to do the partition on my own since it isn't hard at all. You don't need any program. Just do it through Windows 10 like you showed. It's pretty straight forward, don't fear.

1GB = 1000 MB, so if you want 40GB type 40000MB. If you are still confused you also have good YouTube tutorials.

Yeah, it's not really hard. I have done it only once in my life so far, and I did it without any tutorials. Although if you are unsure how and what to do, just go to youtube or google for answers with provided pictures and easy to follow steps

On Windows a gigabyte (GB) is 1024 megabytes (MB), this is NOT true of all operating systems. So, if you want a partition that is 40GB you would use 40960MB as the space remaining. The prompt is asking you how much to shrink the partition by which, is the partition size minus the size you want it to be (eg: 952568MB - 40960MB = 911608MB).

PS: While rare, partitioning attempts can fail which, can result in data loss. It is advisable to have a backup of anything valuable on the disk, including the OS.

I suggest doing this through disk management software instead of using the default Windows disk partition. The reason being some of the disk partition tools can do it lot easier and also understand that they can have less fragmentation. You just have to make the simple settings that work out for you. I don't think Windows 10 would be offering it any harder. The settings are lot simpler and you can find video on youtube.

I actually find it interesting that you would partition it. When I bought my laptop, it came with a 256 gigabyte solid-state drive, and a 1 terabyte standard HDD. Both were partitioned into two drives, so I technically ended up with four drives on there. For whatever reason, that was just silly to me. I can do two drives, but I ultimately prefer just having one so I ended up changing things and combing the SSD into one drive, as well the HDD. I don't know if there are any benefits to partitioning your drives, but I just feel more organized this way.

Thank you for the information in this discussion. I am not techie although we have a desktop at home that would probably need some tweaking for the capacity to be maximized. We currently have 500 GB of disk storage and I feel that it needs to be partitioned so that the master disk will be separated from the data disk. Or perhaps it is easier if I would buy another hard disk for the purpose?
