New 1TB Green drives WD10EADS

I have eleven WD10EADS drives working in a USB EZ-DOCK Kingwin docking station to perform server backups. I have two new drives manufactured on 31 OCt 2009 that are not being recognized by the windows server disk management configuration.   The same two drives I have taken and put in as a second drive in a Vista box and formatted NTFS but still not recognized. Are these two built differently from the other eleven WD10EADS that are working properly? Is there a specific manner I need to format the NTFS?

You will need to talk to kingwin and see if those drives are even compatible.
