I just recently changed out my HD. I got an enclosure to swap and everything but in the enclosure box was a plastic film it said to place on the back of the HD so I did. BUT when I put the new HD into my MBP I realize I didn't take the plastic film off the back....is this ok...should I take the cover off and remove it? On one hand I think it's ok because the enclosure box told me to put it on but then I realize it wasn't for the MBP so I don't know if the HD ever gets heated and the plastic will be a bad thing... Thanks for your advice as always!
