I just got a LaCie 5TB mobile drive. I didn't want any of the free software included so I just plugged it into my PC (Windows 10) which my computer recognized immediately. I started transferring 2TB of hi-res files from a solid state drive onto it. The transfer is only 92% complete after 24 hours(!) Have I screwed up by not using the setup assistant first? I had read that the drive is plug & play... Also, while the files were transferring I was seeing song titles that I know weren't on the host drive. What's up with that?
