What jumper setting do I need to add a second 3.5 hard drive into my PC.

I am sure your missing jumper setting.

so you should change hdd jumper setting.

how to change u r hdd jumper just visit this site.

you will need to set the jumpers on the second hard drive to slave. Unless they are sata drives then you should have no problem.

If these drives are IDE deives then check the jumper settings on these drives.
The jumper setting for master (MA) and Slave (SL)
If one of these drives is on the same data cable as the hard drive the the jumper setting for this drive MUST be set to Slave (SL) because the hard drive will be jumpered as Master (MA).
If both of the drives are on the same data cable and the data cable is plugged into the second IDE controller then one of the drives MUST be jumpered as Master drive and the other as Slave drive.

Hi,

Yes, you can add additional hard drive.Please follow the below steps to add the drive sucessfully.

STEP 1:

Make sure you have room for an extra hard drive, here's one way to do this:

1. Restart your computer and go into the BIOS menu as per below instruction.
Steps to enter BIOS:
After turning ON, immediately press the F10 key if your computer was built in 2006 or later (came with Vista). Press the F1 key if your computer was built before 2006 (XP or earlier). Press the key once every second until a BIOS Setup utility screen opens.
2. Go to the "Standard CMOS Settings."
3. In this menu, you will find four settings labeled as follows: PRIMARY MASTER:, AUTO/PRIMARY SLAVE:, SECONDARY MASTER:, SECONDARY SLAVE:. Change all fields to auto detection.
4. Reboot your computer.
5. On the first or second screen, you will see something like the screen above and it will say detecting (drive(prim/sec)) : (name of the drive if present). If any of them say none, remember which drive it is. If all of them have a drive name, all your bays are filled and you can't add a new hard drive without removing a disk drive or hard drive. Consider making an external USB drive.

STEP 2:

1.Shut down your computer.
2.Unplug all of the cords from the back of your computer and pull the computer out from the desk.
3.Remove the case screws. If you're having difficulty, it's a good idea to consult your manual on how your particular case is removed. Put the screws in a safe place so you don't lose them. Remove the side panel and place it out of the way.
4.Find the area where all the flat ribbon cables (or SATA cables, which are smaller and usually red) connect to the main board. Find the cable that corresponds to the free drive either primary or secondary.

STEP 3:

1.Set the jumpers so the drive knows whether to act as a master or slave. The jumpers are the set of pins on the back of the hard drive. They'll have a couple of rubber or plastic blocks covering some pins. Find the diagram or instructions for your new drive on to set the jumper for the master/slave.
2.Find the empty bay in your computer case. Using the screws that came with the drive or computer case, mount the drive.
3.Connect the cable to the hard drive. If it won't go in, make sure that the safety bump is aligned with the hole.
4.Connect a Molex power cable, (a smaller connector with red, yellow, and black wires.)
5.Put the side panel back on the computer and put the screws back in.
6.Plug all of the cables back into the rear of the computer, and connect them to their power sources if you unplugged them.
7.Boot up the computer. Go into your BIOS at startup.Check the BIOS auto detect to ensure the second drive is detected. On the screen that shows that primary master/slave,secondary master/slave you should see the name of your new hard drive.

All hard drives have a set of jumpers on the end by the power connector. There is also a diagram of the location of these jumpers, for Master or Slave, or maybe Chip Select. On each IDE cable (2 connectors) there will be one Master, one Slave as identified by these jumpers. These jumpers are quite small and easily misplaced, so be careful !!!

yes with a double connection hard drive lead.setup 1 hard drive to master and the other to slave on the hard drive jumpers situated on hard disks.setup the master to the connection at the end of the lead and set the slave to the next hardisk lead connection down.remember to connect hard disk power leads.

(if both drives on the same cable):
Your boot drive goes at the end of the primary data cable.
Your second drive goes on the middle connection of the same cable.
The red stripe on the data cable needs to be closest to the power connection (red stripe to pin 1).
The jumper on the boot drive set to master.
The jumper on the second drive set to slave.
Look in the BIOS to make sure it sees both harddrives.
Boot the system.. it will need to be partitioned and formatted if not already..

Ok... one end of the ide cable goes to the board... make sure that's plugged in correctly and has a blue connector.... second... the last drive on the other end has to be the master... the drive before that is the slave... if that setup is not working ensure that the drivers are set for master and slave... also make the power is pluigged into both drives

You may have the jumpers on the hard drive wrone.
Either it has to be your primary hard drive set for master and the second one set for slave or both set for cable select.
You may also have to go into the bios and turn on the secondary hard drive capability.

Update: SATA II drives do have jumpers to make them backwards compatible with 1.5 Gb/s (SATA II drives are 3.0 Gb/s). So if your system is older and can only handle SATA (first Gen) then you have to add a jumper (Seagate has the jumper setting on the drive but sometimes supplies no jumper i.e. you have to have your own).
