FAQ
Frequently Asked Questions
No. Plug and play refers to the system automatically detecting and configuring a new device. Hot swapping specifically refers to the physical act of adding/removing the device while the system is powered on. A device can be hot-swappable but not plug and play, and vice versa, though they often coincide.
Most modern USB devices (flash drives, keyboards, mice) are designed to be hot-swapped. However, you should always use the 'Eject' or 'Safely Remove Hardware' option for storage devices to ensure all data has been written before removal to prevent corruption.
The opposite is cold swapping, which requires the system to be completely powered down before a component is added, removed, or replaced.
It is safe if the component, the interface (e.g., USB, SATA), and the operating system all explicitly support the hot swap functionality. Attempting to hot swap a non-hot-swappable component (like a traditional internal SATA drive without proper support) can cause damage or data loss.
