Some PCs may also have multiple disks those are physically separate, so you can't merge them. Keep in mind the main disk in your PC will have multiple partitions that are required for Windows to work. You'll see a list of disks and partitions on your PC, including the partitions in each disk. To check if your PC has multiple partitions, right-click the Windows icon on your taskbar and click Disk Management.

But if that happens because of a hardware failure, a partition won't do much to help you.

To be fair, there is a potential benefit to partitions, because they can separate the OS from your files, so if something is corrupted, you can reset the OS partition without losing your files. Here, you can choose whether you want to back up important folders on your PC (Documents, Pictures, and the desktop) to OneDrive, automatically upload photos and videos from devices you connect to your PC, or automatically upload screenshots you take. However, your focus is on the Sync & backup tab, which opens by default. Here you can find a few important settings across different tabs. Here, you can sign in if you haven't already, or you can access your OneDrive settings with the Help & settings button. If you want to change your settings, click the corner overflow icon (the arrow icon) on the right corner of your taskbar and then click the OneDrive icon (it looks like a cloud). When you first turn on your computer, you're already asked to set it up, and it's automatically connected if you sign in with your Microsoft account. OneDrive is Microsoft's cloud storage service, and it's integrated with Windows 10 and 11 out of the box.
