Forget about jumpers on SATA drives. They are jumpered at the factory. IDE drives need to be jumpered so that the IDE channel can determine which drive is the master and which is the slave. If you jumper IDE drives as "cable sellect" the HD at the end of the IDE cable will be seen as the master and the one closest to the mobo as the slave: http://www.seagate.com/support/kb/di...ll_tshoot.html
