Q: Why does my new cloned drive not show up?
A: It mainly happens in Windows OS
The target drive goes offline happens because of signature
collision between the source and target drive(they are
exactly same as each other after cloned).
Solutions:
For Windows 7 or later:
1) Right-click This PC -> Management -> Disk Management.
2) Right-click on the disk that is marked as Offline or Missing.
Select Online command from the drop-down menu.
3) On selecting the option Online, Windows will generate a new
disk signature.The target drive will come back online, and both
drives share the same name.
