DL2GO hidding the original drive letter
After mounting the stick with DL2Go the original letter should be hidden and there should be no windows error, because this is confusing for the user.
Our development team evaluated possible technical solutions to hide/show drive letters in Windows “on the fly”. Currently (with Windows 10) it is not possible to manually hide existing drive letters (1) in a reliable way, (2) on the fly without any user interaction and (3) without possibly hacking into Windows core features.
Because of these circumstanced we will not be able to deliver the demanded feature, although we understand the customer value for it.

You can change the policy for the Stickletter (the original letter) from Acces not allowed in Read-only for the Domain User group, or even the group Authenticated User so that Windows does not break in the drivelock denial with the disadvantage that they SEE the container file (DLV) and other files what a normal user mostly will not understand, but it is better than the error. So it is a good remark from the customer Winklhofer, the interface of DL2GO has more of these little shortcomings for years.
