Usually, a volume is made with a specific file system like NTFS, FAT32, or exFAT. A different drive letter or mount point in the operating system lets you tell each disk apart.

Volumes help people better organize and handle their data by separating content based on file type, user, or application.

Before you trying to add a new volume on a hard drive, it's necessary to check if there is enough free space on the disk to create a new volume.
