I just got my Mid 2011 iMac back today after it's 1TB Seagate hard drive was recalled last Friday. I am very happy to see that it was replaced with a Western Digital (Model WDC WD1001FALS-403AA0, Caviar Black)!! I was fearing that they would just put in another Seagate. I, as well as many others, have had multiple issues with that brand. My old computer's Seagate HD failed on me, and my new iMac's Seagate was recalled. I have also read of many other people's Seagates failing. On another note, my computer was returned with a lot of debris behind the glass screen. It's very easy to remove and clean with a suction cup, as it's held in by strong magnets, however each time I get rid of the dust I see, new dust appears elsewhere. Anyone have any tips on getting out all the dust thoroughly? There is also a small nick in the aluminum of the stand, which wasn't there before, but I think I can live with that..
