Issues with some USB flash drives on Windows

On Windows, we use the following command to detect removable media on the system:

wmic logicaldisk where drivetype=2 get deviceid

This checks for a special bit descriptor on the flash drive which indicates that the USB flash drive is a removable device. This should work as expected on most new flash drives. On some older drives, this bit may not be set leading to drives getting recognized as a local disk instead of a removable drive, which can lead to a false negative.

The code was inspired by USB Drive Detector, which is written for Java.
