I ran into the same problem of Acronis not recognizing the new USB-attached (USB-to-SATA adapter) SSD as WD/Sandisk, although mine is a SSD Plus, not Ultra. I opened Device Manager, expanded Disk Drives, found the Sandisk SSD and double-clicked, went to the “Volume” tab, selected “Populate” at the bottom. Acronis then recognized the drive as WD/Sandisk and proceeded.
Other problems I had with Windows 10 Home 18363.657 -
Did not get “Restart” prompt after going through Acronis setup the first time. I got a message in notification panel/taskbar that Acronis was paused and to restart, and did so, but no “pop up”. After manually restarting I had to go through Acronis setup again and then got the pop-up message and was able to click restart from there.
Acronis did NOT automatically start after reboot. I had to go into BIOS settings. For Windows 10 you have to go into Start-Settings-Update & Security, Recovery (left pane), Advanced Startup-Restart Now. After boot select Troubleshoot, Advanced Options, UEFI Firmware Settings, Restart. After restart BIOS settings are displayed. In BIOS boot tab all I did was disable Fast Boot, as Acronis was already #1 in boot order. After saving and exiting BIOS settings my laptop booted into the Acronis clone operation.
The Acronis displayed “Time left” was not accurate at all for me. For a 500GB drive it took about 2 hours 10 min from start (once I got things working) to finish.
