Recuva help with mapped NAS

Before I buy a pro version, will the pro version detect a Nas that has been mapped and has a drive letter?

The free version does not detect anything other then C. I do not have partitions.

The pro version says is has enhanced drive detection but they may be talking about partitions for all I know…

Taken from Recuva documentation

Recuva is capable of recovering from NAS devices, however the drive needs to be connected directly to the machine via USB/IDE/SATA. Recuva is not capable of recovering data over a network
