When you have a single drive installed in the computer it is usually set in Master mode.  If you add another hard drive to the same channel (IDE cable), you need to set it as the slave.  This is accomplished by setting jumpers on the hard drive.  They act independant of each other and will show with their own drive letters.  Most drives have the settings for the jumpers clearly marked but some don't.  You can visit the manufacturers site and find the information for your particular model drive.  Some of the drives will have a cable select jumper and this means that they will act as either a master or slave depending on their position on the IDE cable.

Dassa has forgot a couple of things you should also configur the second hdd in the bios. when the computer detects the hdd then you should use fdisk to partition the disk. format the disk and ready. Now you can save to the disk you want but you must understand it is not UNIX zo you will get multiple drive names.

I hope this is usefull information for you

To address the question on speed.  There should not be any difference in theory between a master and slave.

you have to tell the comp where you want data saved ,, C:\new folder,,,C:\my documents,, or (slave drive) D:\name of folder....(assuming D: is the slave)

Each hard disk will get a drive letter and that's the one you want to save to - assuming you're using Windows.

disks are identified by their assigned bios hooks

80h = disk 0
81h = disk 1

(80 and 81 are the only disks handled by BIOS)

82h = disk 2

etc etc

all disks above 81h are handled bi bios hook extensions, either in hardware or in software (drivers)

I'm also curious, too. Can ya tell me how does the master/slave jumper ACTUALLY work? IMHO, HDD's slave jumper will set its controller to become "child" controller of the master drive. Is this correct?

There is no diff between master and slave. (it was back in the old IDE days).

All it does is tell the drive if it should be "Drive0" or "Drive1"

And if i recall correctly, it also tells the drive (if it is slave) "Do not announce until Drive0 is online".

The solution to the question is a combination of this answer and other people's answer on speed and how the HDD saves. so this answer should be viewed in conjunction with the other answers also.
