 IDE Interface   (Site not responding. Last check: 2007-10-13)
The primary drive is the master, and the second drive is the slave.
On most drives, you tell it to be a master or a slave with a jumper on the drive itself.
Setting the drive as either master or slave tells it to ignore the commands for the other drive and to only act on ones meant for itself.

 IDE Interface
The drive has the ability to lie to the system BIOS and make itself logically appear as a known device type even if the drive is physically different from the know device.
To avoid a potential conflict between the drives, one drive is designated as the "master" and one as the "Slave".
Integrated Drive Electronics (IDE) is the name for the AT Attachment (ATA) design, and IDE has the drive controller built into the drive itself.

 Hard Disk Drive Guide - What is an IDE Hard Disk Drive
Prior to these drives, hard disks were interfaced to a PC motherboard via an expansion board known as a hard disk controller.
The development of the IDE hard moved most of the electronics and firmware (low-level software on a chip) from the controller to a printed circuit board on the drive itself.
In the process, a buffer/cache' memory was added to the electronics to speed-up the process of reading and writing hard disk drive data.

 Integrated Drive Electronics (IDE)
Drives that use the interface officially known as AT Attachment or ATA are also often called something else entirely: Integrated Drive Electronics or IDE drives.
The reason for the name, of course, is that the IDE interface was the first where the logic board was integrated on the hard disk itself.
As described in some detail in the overview and history of the interface, drives prior to this point had the hard drive control logic on a separate controller card that plugged in a system bus slot.

 Installing a New Hard Drive
IDE drives have a 40-pin connector, which on classier drives is surrounded by a plastic rim with a slot cut out of it - a "keyed" connector - which with a matching cable makes it impossible to connect the drive the wrong way.
Hard drive power connectors are almost exclusively the standard four pin Molex type, renowned for their one-in-three ability to practically weld themselves together.
No modern drive needs to be low level formatted by the user, which is just as well because practically no modern drives actually CAN be, although many will accept a low-level format command, simply erase all of their data, and then report that the format is complete.

 AT Attachment - Wikipedia, the free encyclopedia
On old BIOSes (486 era and older) the drives are often misleadingly referred to by the bios as "C" for the master and "D" for the slave.
It is not possible to initiate another command on another drive on the same interface, or inform the first drive of additional commands that it should perform later (capabilities referred to as "overlapped" and "queued" operations, respectively), until the first drive's read operation completes.
Hard drive performance under most workloads is limited first and second by those two factors; the transfer rate on the bus is a distant third in importance.

 Data Recovery History
The original concept was to cluster small inexpensive disk drives into an array so that the array could appear to the system as a single large expensive drive.
The collection of drives in a RAID Level 0 array has data laid down in such a way that it is organized in stripes across the multiple drives, enabling data to be accessed from multiple drives in parallel.
This drive is used to store parity information that is used to maintain data integrity across all drives in the subsystem.

 Windows IDE Hard Drive Cache Package
The Windows IDE Hard Drive Cache Package provides a workaround to a recently identified issue with computers that have the combination of Integrated Drive Electronics (IDE) hard disk drives with large caches and newer/faster processors.
Modern IDE hard drives typically store disk writes in a hardware cache (temporary memory) and write the data to the hard disk later.
As processors have increased in speed, the shutdown time has decreased to the point that data may still be in the hardware cache when a computer is turned off, and that data may be lost.

 How To Change A Hard Drive - Popular Mechanics
If you're using two EIDE (Enhanced Integrated Drive Electronics) drives, like we are, and your system isn't too old, you'll probably be able to use the Cable Select jumper position.
When two EIDE drives are connected to a single interface cable and are configured to use Cable Select (the default jumper position), the drive attached to the end of the cable is the master, or bootable, drive.
The drive in the middle--connected to both the motherboard and the master drive--is the slave drive.
