The Zengaku Computer System has a function to notify users by email when logging off without unplugging USB flash devices.
ACCC (Academic Computing and Communications Center) and satellites do not accept requests for retrieving USB flash devices etc. for you, but by setting the destination of the notification to your own email address (mobile mail address, etc.), you can easily retrieve it by yourself.
To set the destination address, please follow the User System (accessible only from on-campus) .
