“I just bought a Samsung 840 and tried to use their data migration software with a standard USB 2.0 external enclosure (it didn't come with the USB cable it's supposed to). It gave me the attached results. Does anyone know why it thinks 405GB (or 437 with the additional 32GB it requires) is greater than 465GB? Cause I was told Samsung Data Migration not enough space, and it tells me to delete files to make space.”
