hi all i have one 500 gig lacie external hard drive that is almost full. I bought a second 1 TB Prestige external hard drive that i now want to attach to my pc while still leaving the old one attached. I do not leave my external hard drive on except for when it is in use. What i want to know is, Is it possible to set up the second hard drive and leave the other one attached to the pc or will their be conflicting issues? is it just as easy as plugging it in and turning it on or is their special steps that should be taken? Can they both be turned on at the same time without issue? Thank you for any help
