I have Win 7 with 3.1 USB drivers booting from an M2 on a Z390-E mobo and the M2 is listed as disk 0. I can't believe I did it without your help but I'm right where I want to be.

Now I want to add 3 HDDs:

Work
Data, and
Backup (manual, mirror source to target, when I feel like it. A dupe of Work)

For this I bought three new 2TB Seagate Barracuda HDDs

  • Can I just add HDDs from this point?
  • Do they have to be mentioned in the BIOS?
  • Should they be designated as GPT or MBR?
  • Can you think of anything I should know before I screw up?


Thanks - rev
