I have just installed the Windows 8.1 update and I assume that the issue described below was caused by the update.
My Drives list on DOPUS (using "Drive Buttons") used to show all physical drives. Now it shows not only all physical drives, but also a drive described as "Seagate Backup Plus Drive". The tooltip for it is "mtp://Seagate Backup Plus Drive". I do indeed have Seagate backup software installed on an external drive (Drive M:), and this drive is shown on the drives list. However, the Seagate Backup Plus entry did not used to be shown on the drives list. Moreover, when I click on the button there is no data shown in the respective window. Is there a way to eliminate the display of the Seagate Backup Plus Drive entry in "Drive Buttons"?
