forgot to transfer the hard drive emi foam
So about two months ago my iMac's hard drive dies so I replace it; no problems, easy enough. Been using it for the past two months or maybe more perfectly fine; still no problems.
And today I look at the old one sitting on my desk and see the EMI foam is still on it.
Is this important? What purpose does it really serve.
I know about EMI but I've never herd of a computer needing one little tiny square of foam on it's hard drive to protect it. I've only ever seen a problem from having 50+ computers all with open cases next to each other, and space heaters. So is it really worth taking it all apart again to stick the foam on the new HDD?
Thanks in advance
