Seagate 600 SSD, Failed Windows 8.1 Install, Drivers needed?

Hi

I have a Lenovo Z570 and seeking to upgrade it with a 480GB  Seagate 600 SSD.  I tried to clean install Windows 8.1, but after successfully creating the necessary partitions, it failed to write the Windows files to the disk.   A dialog then appeared stating there was a device connected for which it needed a driver. OK.  I'll get the driver.  But I found none. So I'm stuck.

Does anyone know how to get past this and install Windows onto this SSD?

Thanks!
