What should follow after backing up your data when adding a new hard drive?

When adding a new hard drive, the logical next step after backing up your data is to turn on the computer. This action is necessary to initiate the process of hardware detection when the new hard drive is installed. Upon powering on, the system will recognize attached devices, including the new hard drive, and prepare for the subsequent setup and configuration steps.

Once the computer has been turned on with the new hard drive in place, the operating system will typically lead you through the process of formatting and configuring the drive. This ensures that the drive is ready for data storage and can be effectively utilized alongside the existing drives in your system. Other actions like installing the new hard drive or configuring it using Device Management are indeed important, but they occur only after the computer has been turned on to recognize the hardware.
