I just returned from an out of town visit where I upgraded 2 different laptops… to Sandisk Ultra II SSD’s…
One had previously had a Seagate Momentus XT Hybrid drive, and other was another mfg (which immediately went into a USB Enclosure for a data use…)…
Both were updated flawlessly with Acronis…
From what you posted, it might be that the Acronis you got was a free copy from a drive mfg, and they may have ‘altered’ it… so it only works with their drives… ???
