This is my problem: https://www.youtube.com/watch?v=en4Rmb1a… The optical drive sounds like a machine gun when I start my Imac. Is there a way to shut the optical drive off without removing everything ? ANy ideas what to do? Thanks for your help.
Sorry guy I don’t think your optical drive is the issue here. First, the optical drive doesn’t start up right away its a bit more delayed in the POST process. This sounds more like a fan blade has failed and is hitting the fan case cowling. Lets see if we can ID which fan needs service. Install this app TG Pro.

You want to get the system warm so the fans run. If you get the full version it has a diagnostic service which should point out the defective fan. iMac Intel 21.5" (Mid 2010-Late 2011) CPU FaniMac Intel 21.5" (Late 2009-Mid 2011) Hard Drive FaniMac Intel 21.5" (Late 2009-Mid 2011) Optical Drive Fan Update (04/17/2019) If you’re sure it’s the optical drive, try just disconnecting the cable from the drive. Carefully pry the cable end off the back side of the drive there’s just enough room. I would try to take the optical drive fully out following this guide iMac Intel 21.5" EMC 2428 Optical Drive Replacement If you are having a problem with a screw you’ll need to find a way to get it out.
