Not a dead drive. SB850 chipsets and onward had a problem initializing certain samsung drives (mainly F3 models). That clunking sound can be fixed with a firmware update. I had the exact problem, this fixed it.http://www.samsung.com/global/business/hdd/faqView.do?b2b_bbs_msg_id=308
Make an old school boot disk with a USB, just something to get you to command prompt (like a win 98 boot disk or w/e) run f3.exe, done deal.
Sorry for resurrecting an old thread, I just spent hours trying to figure out this exact problem and stumbled across this on google. I felt this deserved a proper answer instead of the cliche "its dead, rma it" response.
