Continuing issue - Already on 2 computers message after replacing hard drive

[kutani]

Best buy. At the time, it was the only software on their besides the operation system. It was a toshiba HD..
I didn't have much music on it at the time as well so when I learned that it would need to be replaced, I didn't think much of it. I figured if I have a problem, its best to deal with it now rather than after I get a ton of data on there...

I upgraded to a higher speed, much larger cache and faster read rate Seagate. I didn't want to take a chance. I'm a vocalist and I'm using this for performing and I need the music to be there.
