This works much like a transactional file system, where either the file is modified or it is not. The host system sends a message to the device, marking a file for deletion, then the device removes the file upon acknowledging the signal. The host system can then send a message to the device requesting that a file be downloaded, which will be sent by the device after acknowledging the signal.

When plugging in a device such as an MTP device, the host system queries the files on the device. However, MTP, or Media Transfer Protocol, operates at the file level rather than as a large unit of mass storage at the block level. Hence, the “Safely Remove Hardware and Eject Media” message. It assumes absolute control over the file system similar to that of a hard drive.Īs such, unless explicitly commanded by the host system to sever the connection between the devices, there is a chance that the host computer might corrupt the file system. When plugging in USB mass storage devices, it gives a host computer undifferentiated access to the mass storage. SuperUser contributor Carrein has the answer for us: I am interested in understanding this for all versions of Windows (XP and later), so please include the applicable Windows version(s) in your answer.Ĭan you simply pull the USB plug on MTP devices connected to Windows? The Answer But for MTP devices (such as many Android devices) connected to a Windows computer via USB, is it necessary to perform any special or particular procedure before disconnecting the USB cable? I know that after attaching a typical USB mass storage device to Windows, it is important to properly unmount the device before unplugging it in order to avoid the possibility of losing data. SuperUser reader RockPaperLizard wants to know if you can simply pull the USB plug on MTP devices connected to Windows:
