How to Find if USB Storage is Hotplug Ready on Windows

Everyone has at least one USB mass storage device these days. These are great for carrying your important files and portable programs with you everywhere. Some of the USB drives with massive capacities such as 1 TB or 2 TB are also good for keeping backups of your files.

When you are copying files to and from an external storage device such as a USB mass storage device or a USB external hard drive, you cannot pull it out from the USB port or the files will get corrupted. But for some USB flash drives (pen-drives or thumb-drives) it does not really matter if you detach them from your Windows PC in the middle of a file operation. And some of these USB devices, you cannot even remove without first shutting down the Windows PC.

The devices that you cannot attach or remove without first shutting down Windows are called non-hotplug devices. The devices that you can freely attach or detach to a USB port on your Windows PC without first shutting down the PC are hotplug ready devices.
