Hey, literally just figured out what the problem is as I had the same issue.


When mounting a volume it is important that you select the correct partition to be mounted, which seems obvious.

However there is a difference between selecting the

"Harddisk 2" as this will output as "\Device\Harddisk2\Partition0"


"\Device\Harddisk2\Partition1" as this will output "\Device\Harddisk2\Partition1"

You would assume that since the volume has only 1 partition that there would only be one possible option. There are two in this case, 1 is the drive as a whole and 2 is the specfic only partition. Your password will only work on that particular partition and not the drive as whole.

Try your password again but mount the single partition only and not the whole drive.

Hope this fixes your problem as well.
