  • Local Disks: These are storage areas in your PC that house your operating system, software, files, and other data. They can be hard drives (HDDs), solid-state drives (SSDs), or other internal storage devices. Local Disk D refers to a secondary partition or physical drive on your computer.
  • Partitions: A single physical drive can be divided into multiple sections called partitions. Each partition can function as an independent disk drive with its own file system and data.

Now, to sum up, Local Disk D refers to a secondary partition or physical drive on your computer. To be clear, the letter D doesn't mean anything, and it's generally assigned as an identifier for the local disks that do not contain your Windows OS. That is to say, a local disk labeled with the letter C(Local Disk C:) is generally used to store your PC's operating system.
