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.
What are some problems with the primary slave drive?
If you add an additional HD to your computer, the second drive becomes the slave drive because the computer must boot from the Master drive
The second drive.....
Well an optical drive is a cd/dvd disk drive. Slave means it is in the secondary position on an IDE cable. So a slave optical drive is a cd/dvd drive positioned secondary to a different device on a singular IDE cable.
Configure the hard drive as the master and the CD-ROM as the slave.
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.
We generally use the jumpers to set the disk drives as master or slave.
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.
Hard drive as master and DVD writer as slave.
To remove a partition on a slave hard drive you can go into the BIOS. You should look up a guide if you plan to do this.
To allow for two drives on the same cable, IDE uses a special configuration called master and slave. This configuration allows one drive's controller to tell the other drive when it can transfer data to or from the computer. What happens is the slave drive makes a request to the master drive, which checks to see if it is currently communicating with the computer. If the master drive is idle, it tells the slave drive to go ahead. If the master drive is communicating with the computer, it tells the slave drive to wait and then informs it when it can go ahead. The computer determines if there is a second (slave) drive attached through the use of Pin 39 on the connector. Pin 39 carries a special signal, called Drive Active/Slave Present (DASP), that checks to see if a slave drive is present. Although it will work in either position, it is recommended that the master drive is attached to the connector at the very end of the IDE ribbon cable. Then, a jumper on the back of the drive next to the IDE connector must be set in the correct position to identify the drive as the master drive. The slave drive must have either the master jumper removed or a special slave jumper set, depending on the drive. Also, the slave drive is attached to the connector near the middle of the IDE ribbon cable. Each drive's controller board looks at the jumper setting to determine whether it is a slave or a master. This tells them how to perform. Every drive is capable of being either slave or master when you receive it from the manufacturer. If only one drive is installed, it should always be the master drive. Many drives feature an option called Cable Select (CS). With the correct type of IDE ribbon cable, these drives can be auto configured as master or slave. CS works like this: A jumper on each drive is set to the CS option. The cable itself is just like a normal IDE cable except for one difference -- Pin 28 only connects to the master drive connector. When your computer is powered up, the IDE interface sends a signal along the wire for Pin 28. Only the drive attached to the master connector receives the signal. That drive then configures itself as the master drive. Since the other drive received no signal, it defaults to slave mode.
In computing, you can have two disks, the main and the slave - these are set by jumpers on the hard drive. In classical hardware, the main would have priority over the slave. However, with better electronics's, most computers don't differentiate between slave and main anymore.
