Close to two weeks ago I posted a question about AppleCare authorized repair center policies, regarding a Rush fee. It was kinda shady but I let it slide. Note: I did not a pay for the Rush fee. Here is the previous thread link: http://forums.macrumors.com/showthread.php?s=&threadid=60328. Well I got my iMac back. Turns out, it was a defective drive. It took the place 5 days to get it fixed, not including the weekend. Anyway, I checked the drive model number and it is something totally different than the original drive. This, to me, was to be expected. However, the Superdrive on my 17" iMac won't close properly. It gets hung on the external lid that pops down when opening the drive. Also, this new drive seems to be flimsy and not as well constructed as the Pioneer model. The replacement drive is a GCA-4020B. Anyway, your thoughts are welcomed. Thanks.
