Thanks for this feedback! And of course many thanks to fatlip, pichi and the others involved. My 500GB 7200.11 (ST3500320AS, SD15, 5QM2****) has not yet died and according to Seagates serial number check is should not be affected. But I don't have any confidence... I have the same drive and the serial checker gives me the same result. The problem is the original KB article stated explicitly that model WAS affected and models built THROUGH Dec. 08 were needing an update. Now they changed the models affected in the KB article update and say it was only models made IN December. It's confusing the hell of out people and they haven't said why they changed it or if those of us with models not listed in the update need to worry. I can't even seem to e-mail them through the Seagate website for some reason. I get some weird login error even though I'm already logged in via their forums.
