It is preferable that you have the SSD connected via SATA directly when using the Intel® Data Migration Software and that Windows* sees the drive. Make sure the SSD has been initialized. Here is step:
1 - Got to Disk Management (Control panel >>> System and Security >>> Administrative Tools >>> Computer Management >>> Storage >>> Disk Management).
At this point, you will see a message saying that the SSD needs to be initialized. Let the Wizard complete the process. If you are prompted to choose between MBR or GPT, please select MBR. If you do not get this message, please right click on the square box that says Disk #, example ( Disk 1) and initialize SSD. If the SSD is labeled unallocated, that means it needs to have a partition created, in order to do so, right click where it says unallocated and select New Simple Volume. Follow the default options. Allow it to format at the end. Once the process is over, you should see that the SSD is labeled the same as the C: drive and then try the Intel® Data Migration Software once again. However, there are other alternatives that you can try that might help you resolve this issue as well.
