Intel Data Migration Software can display the following message if you use a third-party USB-to-SATA cable to connect the SSD to your system. In this case, replace the adapter.
If an error occurs during the data migration, run a low-level format via Secure Erase included with Intel SSD Toolbox. You can also use the Drive Cleanser, included with Intel Data Migration Software. Try the data migration again.
The capacity on the SSD label is calculated in decimal notation. Most operating systems calculate a drive capacity in binary notation. In decimal notation, 1 GB equals 1,000,000,000 bytes, but in binary notation it equals 1,073,741,824 bytes. It is normal for the operating system to indicate less drive capacity than what is on the SSD label.
If the drive capacity is not the issue, run a low-level format. Use Secure Erase included with Intel SSD Toolbox or the Drive Cleanser included with Intel Data Migration Software. Try again.
