Ok,I'll only have to set the jumper on one, because my new one is a SATA, and I saw that it defaulted to a Master drive in the BIOS.
Re-naming the HDD doesn't erase data..right? It just simply changes file paths, right? I wanna make sure before i do anything xD.
The new HDD is still formatting, so I'll have to try this tomorrow (the back-ups are still saving as well, so they should get done at about the same time).
Thanks for the help, Soulphire =).
