Hi all, First post. I have read a large chunk of the 7200.11 solution thread and although I am not sure that it has helped me, I would like to show my appreciation for those that have put so much effort into helping others. Now to my problem. I have a 4 500gb Barracuda drives and have had two of the St3500320 drives fail. Seagate have replaced them under warranty, buy of course that is small consolation for the grief of losing data. I wish I had known about the 7200.11 fix 18 months ago. I now have a 500gb ST3500418AS that is showing zero capacity. It is detected in bios and disk manager in win7, but does not show up as a drive letter. The drive is partitioned into 3 partitions, (four if you include the one for win7 100mb), and I have been using the drive as a backup for data rather than main boot drive. The drive fails all Seatools tests. My question is could the drive have the same problem as the 7200.11 series drive and respond to the same solution? Also, did it make any difference the 7200.11 fix if the drive was partitioned? I also saw a video on you-tube,
, where the guy had a blown diode and removed it to retrieve his data. I am not sure why he didn't replace the diode or how he knew that that was the problem, so I am very cautious about trying that fix. I hope someone can help, and thanks for the great resource. Baz
