I own a ST3500320AS, puchased Dec 15, 2008. Made in Thailand, firmware SD15. Luckily, I have not experienced a failure yet, but I believe it's imminent based on all I've read. BTW, the Seagate KB article is back up. I just accessed it now: http://seagate.custkb.com/seagate/crm/self...sp?DocId=207931 I am hopeful that those of us who haven't yet experienced failures will be offered a firmware upgrade that will alleviate our fears. Although based on the lack of customer service and quality on Seagate's part, even a firmware upgrade will still have me cringing every time the drive needs to reboot.
