How many drives must be set to master in a PC with IDE drives on the same cable?
Only one master is connected to single IDE cable
How many drives must be set to master in a PC with 2 IDE drivers on the same cable?
Only one, the one with the operating system on it.
Sata drives can a optical drive be master when its a ide?
An IDE Drive is not the same as a SATA drive, for starters. If you want your optical drive to be the master on an IDE channel you can jumper it to make it such. The second drive on the IDE channel must then be jumpered as a slave. If the optical drive is the only drive on the channel then it ought to be jumpered as the master. Alternatively, you may be able to set both drives to "Cable Select" and let the cable position determine the priority. This presumes that your ribbon cable is of a newer design and supports this option.
What is the difference between master IDE and slave IDE?
In computing, the terms "master IDE" and "slave IDE" refer to the primary and secondary IDE devices connected to the IDE bus on a motherboard. The master IDE device is the main drive that controls the bus and handles data transfers, while the slave IDE device is a secondary drive that operates under the control of the master device. Each IDE channel can have one master and one slave device connected to it.
If you are installing a second hard drive into a computer will it still work if you can't change the jumper to slave?
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.

It's not that hard to install a hard drive if you are handy with tools and repairs. But there are a few things you need to know. Depending upon whether you are keeping your old hard drive, and will now have two hard drives, or if you are getting rid of your old hard drive and will only have one hard drive, determines where you plug in the IDE cable and how you set the jumpers. Of course you might have bought a new CD burner and a second hard drive and want to install them both. So there are a variety of possibilities. No matter what your case may be, the two most important things are how the IDE plugs and jumpers are configured. The power supply cable can only go in one way, so that's easy. The power supply is a 4 pin connector.IDE Interface cable: (Also called "Ribbon Cable") * The IDE cable is flat, usually gray, about 2" wide and has three plugs on it. The plugs are 40-pin connectors. One end plugs into the motherboard, and might be blue. You don't have to worry about that end, just leave it where it is. At the extreme other end of the IDE cable, opposite the mother board is the PRIMARY DRIVE (MASTER) connector. Then there is a plug in the middle that is the SECONDARY DRIVE (SLAVE) connector. The MASTER connector on the end might be black, and the SLAVE connector in the middle may be gray. Make sure the MASTER connector is plugged into the Master drive, and the SLAVE connector is plugged into the slave drive. The most important thing to understand with the whole Master/Slave thing, is that the hard drive that boots up your computer must be set as the MASTER. The second thing to understand is this: If there are two drives on one IDE cable, then there must be a Master and a Slave, or both drives must be set to "Cable Select". * If there is only one drive on the IDE cable, then it must be plugged into the end plug, which is the Master plug. Jumper Block, Jumper * At the back of the drive, along with the power supply slot and the IDE slot is the Jumper Block. The Jumper Block has a little, tiny plug in it that connects two of the pins. That little plastic plug is called the jumper. Depending upon where the jumper is plugged into, determines whether the drive is set up as the Master or the Slave. There are 4 possible jumper settings. The jumper setting depends upon how many drives are on the IDE cable and whether the drive is a Master or a Slave.The 4 settings are: * Cable Select - (Usually the default setting) The jumper plug is usually all the way to one side nearest the power supply plug. If your system supports "Cable Select", then the system determines which will be the Master and which will be the Slave. If one drive on the IDE cable is set to "Cable Select", then the other drive must also be set to "Cable Select". You can't have your Master drive set as "Cable Select" and the other drive set as the Slave. If you aren't sure whether you system supports Cable Select, then you can use the standard jumper settings described below. * Master - For when two drives share the same IDE Cable. The hard drive that is booting up your computer must be the Master. Master is also denoted by "Single" on older hard drives. * Slave - Also for two drives * Single - The jumper plug is not present. For one drive on the IDE Cable. MASTER/SLAVEHow many drives? * The computer probably has two IDE cables, with two drive plugs on each cable. This gives you the option of having up to 4 different drives, in many different configurations. * You could have 2 hard drives and 2 CD drives. Most computers come with one hard drive on one IDE cable, and a CD drive on the other IDE cable. * People often put an extra CD drive in so they can burn from one CD to another CD. You could have the hard drive on one IDE cable and the two CD drives on the other IDE cable. * Having a second hard drive is really the way to go for backing up your data. Depending upon how many drives you have in your computer, will depend on how you need to set the jumper , you will need to: plug. And as explained above, there are a few different possibilities.1) No matter what the new configuration is: * Unplug all the cords at the back of the computer. * Remove the cover on the side of the computer * Make a note of how your IDE cables are plugged in. 2) If you are removing a drive:Unplug the power supply from the drive (The 4 wire connector)Unplug the IDE cable (2" wide, flat, gray)Unplug any other wires (Sometimes a 2 wire plug on CD drives)Remove the screws on both sides of the driveSlide the old hard drive or CD drive out.If you are simply putting a new hard drive in place of the old one, check the old hard drive for where the jumper plug is. Check to see if the new hard drive is set the same. If you are saving the old hard drive or need to copy data off it, thenyou will need to install both hard drives. When I bought a new Western Digital hard drive, my old hard drive was still working, and I installed the new hard drive as the slave. The Western Digital hard drive came with software to copy everything from my old hard drive to the new hard drive, and make the new hard drive bootable.If you need to retrieve data off your old hard drive, and the computer won't boot up, then go to the question: How do I get data off my hard drive?You will need something like tweezers or something very small to get the jumper out. The jumper is usually a little piece of white or black plastic, and it's very small.Sometimes the hard drive will have letters stamped into the metal to indicate which slot is the Master and which slot is the Slave. 3) Make sure the jumper on the drive that will boot the computer is set to Master or Cable Select. Cable Select can only be used if BOTH drives are set to Cable Select. If you just bought a new computer and are putting an old hard drive into the new computer, the hard drive in the new computer will already have the jumper plugged into the Master slot or Cable Select. 4) Put the old drive into an open slot in the new PC and secure it with screws5) Connect the open connector from the same cable as the existing hard drive of the new PC. Most computers have two IDE cables. Each of the cables has two plugs on it.6) Boot up the new PC7) In Windows Explorer you should see your old drive now as a different drive letter. I have two hard drives on one IDE cable and two CD drives on the second IDE cable. In my computer, my second hard drive shows up as F: drive. My two CD drives show up as D: and E: drive. My original hard drive shows up as C: drive. 8) In Windows Explorer you can copy or move files to your new drive. I like to right click the Start button, and choose "Explore" as a fast way to get into Windows Explorer.
What does the slave and master and the rest of the things for a hard drive mean?
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.

You had the hard drives you op sys from your old computer made into external drives plugged them into your new computer xp op sys can get all info except what was on 'desktop' on the external drives c?
I always recylce my old drives, mainly because it is so much easier than transfering the data to a new one. It isn't exactly possible to make them "external" drives because they are not configured that way. However, computers are more resilient than people think you can mount the drives in almost anywhere. The one thing that MUST happen is that it has to be on the same IDE cable as your main drive (that is the long skinny cable, the other is a power cable). Also, you have to set the drives to run as a "master" and a "slave" drive. To do this it is best to have the books on them, but you can just put what type of drive it is in a search engine and you should be able to find the configuration settings easily. Once you know the settings, you have to actually manually do it. You do this by getting some tweezers and looking on the back of the drive near the power cable, there will be a couple of rows of pins and you will notice that some of them are covered by a plastic "jumper". Where this jumper is will determine your drives actions. Usually a slave drive is simply no jumpers at all. Once you have the jumpers done, the cables on, and of course the drive screwed to the frame, you are good to go. power it on and see what happens. If you have an operating system on both drives it might ask you which one to go off of though. If you have the op sys on the master it should do it automatically, but you never know. Be sure to not put the shell back on the tower until you are sure that it works though, you don't want to take it off again.

Why did many of the long drives end in kansas?
I must assume you are asking about cattle drives since you don't ask it in your question. Kansas was the nearest rail line for the cattle drives. Kansas City had the largest stockyards for the trains going east.
