In the post to the dell mailing list ( http://lists.us.dell.com/pipermail/linux-poweredge/2010-February/041335.htm= l ) It was pointed out that the user had installed Seagate ES.2 drives, which are enterprise class drives that have been around a while and are kind of the standard SATA enterprise clas drives and are listed so by Seagate: http://www.seagate.com/www/en-us/products/servers/barracuda_es/barracuda_es= .2 These drives were marked as BLOCKED and unusable by the system. The pdf linked to in the dell forum specifically states that the hard drives are loaded with a dell specific firmware. The PDF seems otherwise free of useful information, and is mostly a marketing tool as near as I can tell.
