Both past and present Drives are shown under ADVANCED/DRIVES.
It shows 2 D Drives one of which was shown as a backup.
Drive D is NOT a backup drive any more.
One might be an older disk the other current ( I can't tell the differnce from this screen).
Drive D now contains Data and specifically redirected folders like My Documenta etc which are separately backed up.
How do I remove the old drive from the list without losing the data and add it back as the current D Drive??
