We generally use the jumpers to set the disk drives as master or slave.
Configure the hard drive as the master and the CD-ROM as the slave.
Hard drive as master and DVD writer as slave.
The Harddrive needs to be set as "master" and the CD ROM as Slave.
Here is how I will configure the machine: IDE2 Master -Boot drive IDE2 Slave -Storage drive1 IDE1 Master -DVD ROM IDE1 Slave -Storage Drive2
Mount the drives in the carrier connect the 40-pin cable to the drives set the drive at the end of the cable to master set the drive in the middle of the cable to slave install the drives in the computer and configure the drives
If the Hard drive is IDE (40 pins on the back) you would configure the primary hard drive as Master and secondary hard drive as Slave using the jumpers on the back of the hard drive.
Primary Master Primary Slave Secondary Master Secondary Slave Primary or Secondary will depend on which cable are you using to connect the drive. Master or Slave will depend on the drive's jumper configuration.
That would depend on certain variables, such as whether you were putting it on the same cable as the other drive. In IDE, you must have a Master drive on each channel. The second drive must be set to Slave. You were not clear in which drive you could not change the jumper. Assuming the drive in the computer is alone on the cable, it is set to Master, so your new drive must be either set to Slave and be placed on the same cable, or set as Master and placed on another cable.
Master and slave does not apply to scsi drives
There are jumpers on the drive itself that can be configured to set it up as a master or a slave. Refer to your hard drive's documentation for the pins to use for these configurations.
On the older style ATA drives, now called PATA or simply IDE, each drive chain had two positions for drives. One was called the Master, and the other the Slave drive. The drives performed in exactly the same manner, and the only difference most people would notice was that the Master drive was given a drive letter before the slave drive. In short, a Slave drive does everything a Master drive does.
the hard drive should be set to master...
