CPU spike after hard drive swap

I just upgraded my HDD to 1TB using your guide(s). I noticed after installing the new drive I had a giant CPU spike. It fluctuates up and down quite a bit. does this have to do with the CPU locating files on a different drive or should I be worried about something else?

I suspect Spotlight is running. Depending on how many files you migrated it may take awhile. You can check what is running with Activity Monitor application in the utilities folder.

That's exactly what it was. I didn't think of that right away since it was a clone of the old drive. Thank you though!
