Question: I have a Pentium III running WIN 98 and want to install another hard drive,which was out of another computer but it is running Win Me. I want to still use WIN 98 but want to retrieve programs and use the second hard drive as back up. Do I need to uninstall Win Me from the hard drive and how do I setup my computer to run both drives?
Answer: Make sure that the current hard drive has the jumpers on it configured as Master and change the jumper on the hard drive you are installing to the Slave position and attach it to the other connector on the same cable. Note that it doesn't have to be a pre-used drive that you add, these same instructions will work for new drives as well).
If you have a cd drive in that position move the cd drive to the cable that comes from the next socket over on the motherboard. Doing it this way will give the fastest access times to both drives and will set the new drive as D: (your cd drive will be moved to E: but that is going to happen regardless of which hard drive is which).
As the computer will boot from C: your existing operating system will be the one that runs.
You can then delete whatever files you don't want from the second drive. If there are any programs on the second drive that you want to run you will have to reinstall them so that the operating system recognises them properly.
Note: The above description relates to the use of IDE drives in your computer. If your hard drive you is using a SATA connection then the process is even easier as each SATA drive has its own separate connection to the motherboard instead of having two drives connected via the same cable. This means that selecting between master and slave is not required for SATA drives.
When it comes to selecting which drive you want the system to boot from (if it tries booting from the wrong drive after you plug in an extra drive, there are settings within the BIOS that will allow you to tell the computer which drive it should look at first. Simply open the BIOS when the computer first starts up (pressing the DEL key is the most common way to do this but some computers use a different key - in any case there will be a message on the screen telling you which key to use). You should then be able to select which drive you want the system to boot from. The exact location of this option within the settings varies between the different BIOS chips but should not be too hard to find.
