I am trying to install a hard drive as the primary slave on my computer. But the hard drive came with a jumper shunt and a jumper, I removed the jumper shunt thinking I didnt need it, and went ahead and set the other jumper to slave. But when I turned my computer on the computer wasnt working right so I took it out and everything is fine now. Do I need to keep the jumper shunt on there for the drive to work. Heres the specs for my computer and new hard drive Computer -Custom Built -1.6GHZ -256MB DDR -11 GB HD-Current one set as primary master Hard Drive -Western Digital EIDE drive -7200 RPM -8mb cache -80 GB -MD #WD800JBRTL (Looked at the guide and says nothing about the placement of jumper shunt or jumper, maybe someone else will get a better understanding) I really need help because I am about to run out of room on current hard drive Thanks
