    I have a white 2009 uni-body MacBook that I do graphic design work on. Once a month, I meet with my client in the city. Would there be any issue swapping hard drives back-and-fourth on my machine. I would use my 500GB drive with all my apps installed, etc. 99% of the time but when I had to take my laptop out of the office I would swap the drive to a 250GB drive that just has an install of OS X (no apps). Would this cause any issues with the firmware by doing this?

    Won't cause any issues with firmware. "Wear and tear" on the all the parts touched during swapping would be the main concern.

    Any reason you don't just put the bare OS on a separate partition?

    Why would you think your firmware would have anything to say in that matter?

    Your description is also quite vague, so more details would make it easier to see why you think there would be a problem.

    If not needed pull the DVD drive and fit the other HDD in there and pick which drive to boot from without pulling any drive and wearing out hardware.

    I pulled mine and put the DVD in a usb caddy so still had a DVD drive.
