Hidden disks refer to storage devices that are not immediately visible or accessible to users within a computer system. These disks can be part of a larger storage solution, such as a hard drive or solid-state drive, and may contain important data or system files. They are often used for backup purposes or to store system recovery information. In some cases, hidden disks are intentionally concealed by the operating system to protect sensitive data or to optimize performance. Users may need specific tools or commands to access these disks, making them less straightforward than standard storage options. Understanding hidden disks can help users manage their data more effectively.
