Here is how to make it work
The Sandisk or WD drive must be inside the laptop computer; the old drive can be connected with a usb cable.
When you connected the Sandisk using a usb cable, the Acronis program sees it as a usb generic drive … but when it is in the hard drive caddy ( laptop) the system will recognise it as “branded”.
Then Acronis will work and do a remarkable job!
