Regression: Recuva does no longer display logical drives

Hi

I was using version 1.42.544 and recently updated to version 1.50. I now find out that logical drives, such as those created by ImDisk, are no longer displayed in the list.

Now, only volumes found on physical devices are displayed.

And with the wizard, if I select one of these drives, I get "Invalid drive for scan."

Why such a regression? Will this be fixed?
