I have finished building my new computer including a 3TB SATA HD with Windows 10 installed. In my old computer I have a 1TB SATA HD with Windows XP installed. I have files I need to transfer from the 1TB HD to the new 3TB HD, then format the 1TB HD and use in the new computer. Both HDs are Western Digital Black SATA 7200RPM. Would it be safe to put the 1TB HD in the new computer, transfer the files, then format the HD using the new computer? Will it be okay if there's another version of Windows (XP) on that 1TB HD while I have Windows 10 installed on the 3TB HD?
