But it does have to be setup correctly.
If you use XP, just hook it up and use the XP cd to boot with and partition it and format it without doing an installation.
If you use W98/ME, do the following:
FDISK- FORMAT SLAVE/SECOND HARDDRIVE
You should have two IDE controllers on the motherboard. I would suggest that you put the two harddrives together on one cable daisy-chained together on the Primary IDE controller and the cdrom on the secondary IDE controller. Make the first harddrive the master (the one you are using now) or the master with a slave (look at the jumper settings on the back of the drive to do this), and then make the new harddrive the Slave (same jumper location).
Then, boot up to go into the bios, then go to the Auto HDD detection area and run the program saying yes to all the drives detected as long as the sizes are recognized correctly. When it is finished, go to Save and Exit and boot up with your boot disk that goes with your operating system.
NOTE: If your bios can't see the whole harddrive, you CANNOT use the ezdrive/ezbios program that comes with the harddrive on a floppy disk UNLESS the BOOT harddrive also has the program installed on it because Windows won't be able to see the drive as a slave drive when you get to the desktop although DOS will be able to see it just fine. If ezdrive/ezbios is already installed on the first/boot harddrive, you can use the software on the slave drive to do the following steps through that program instead...otherwise, you will have to consider using the new harddrive as the new bootdrive instead of using it as a slave drive.
Use the boot disk for the operating system you want to put on the harddrive (if you need one that gives you cdrom support go to http://www.bootdisk.de and download one now and make sure you get the right version for the windows that you will be putting on the harddrive and then extract that file to a temporary folder on your harddrive somewhere, read the readme file to know how to create the disk, then put a floppy disk into the drive and follow the instructions from the readme file to get your disk made. If you downloaded the bootdisk and it's an .exe file, you can just click it and it will start to create the bootdisk for you automatically. Also, when you use the bootdisk you downloaded, it will default to being the R: drive for the cdrom, but this is only temporary until you reach the windows desktop.
To check for your version windows, go to Control Panel\System and under your Registered Owner name, you will see some numbers. If the number is 4-00-950 with no letter or the letter "A" after it, you have W95A. If the number is 4-00-950 with a letter "B" or "C" after it, you have version W95B or W95C and will get the W95B bootdisk. If you have Win98 or WinME or Win2K or WinXP, this is an obvious choice for you from the site.
One last piece of advice regarding bootdisks before you format the drive.....go NOW to Add\Remove Programs\Startup Disk and create two more bootdisks (have your windows cd handy because it will ask for it). I've seen bootdisks go bad for no apparent reason when you least expect it, so make sure you have a couple of them handy just in case. Don't try to make a copy of the one you have using the A: drive copy command because the copy won't work at all since there are hidden and system files on it and they don't copy over....you have to make the new bootdisks from the Startup Disk tab. However, this will NOT work with W95 because the StartupDisk tab won't give you cdrom support so you will have to download a bootdisk for it instead.
Also, for W98, if you create the bootdisk from within windows, you will need to go here to download the newest version of FDISK.EXE then copy it to the bootdisk, allowing it to overwrite the older version. This way you will have support for larger harddrives.
FDISK LIMITATION WITH 64GB DRIVES:
Why does FDISK not recognize my disk (or RAID array) which is larger than 64GB?
There is a bug in Microsoft's FDISK under Windows 95B, 98 and 98SE that can be corrected by downloading a newer version. See Knowledge Base Article Q263044 for more information.
When you use Fdisk.exe to partition a hard disk that is larger than 64 GB (64 gigabytes, or 68,719,476,736 bytes) in size, Fdisk does not report the correct size of the hard disk.
The size that Fdisk reports is the full size of the hard disk minus 64 GB. For example, if the physical drive is 70.3 GB (75,484,122,112 bytes) in size, Fdisk reports the drive as being 6.3 GB (6,764,579,840 bytes) in size.
NOTE: This hotfix is not designed for 48-bit logical block addressing (LBA) hard disks, and it is not supported on hard disks larger than 137 GB. However, even if the drive is physically larger than 137 GB, if you create partitions
smaller than 137 GB, this FDISK.EXE version will work correctly. (THE FORMAT COMMAND WILL SHOW THE DRIVE AMOUNT IN DOS TO BE OFF THE MARK, BUT WILL BE CORRECT WHEN YOU GET INTO WINDOWS ITSELF)
Direct English Version download:
This package installs the updated Fdisk.exe to the Windows\Command and Windows\Options\Cabs folders, on a computer running Windows 98 or Windows 98 Second Edition. If you are starting a computer from a Windows 98 Startup Disk in order to partition and format the hard disk, you should copy the updated Fdisk.exe from the Windows\Command folder to the Startup Disk, replacing the original Windows 98 or Windows 98 Second Edition version of Fdisk.exe on the Startup Disk.
You can also get around the 64GB limitation of the Windows9x FDISK utility by specifying the desired partition size as a percentage of the total disk size rather than as an absolute size. Alternatively use a freeware FDISK replacement such as FreeDOS FDISK that supports up to 128GB.
One person wrote in a forum: ... as an update on disks greater than 64gb, the FreeDOS FDISK utility does work. First of all, the operating system must be specified in FDISK.INI for it to recognize FAT32. Secondly, reporting of partition size is somewhat peculiar. For a partition between 64 and 90 GB, I have one listed as 39,184GB under Option #4 (Display Partition Info) and -26,402GB under Option #5 (Change Current Drive). I have a 3rd IDE drive connected to IDE1 which is set up as an extended partition. Its letter is changed while in Windows than it is with the FreeDOS FDISK. Finally, the FDISK only works if it is on a bootable floppy. Trying to run it in a DOS window under WIN98 causes the system to freeze. This is a suitable workaround for the 64gb limit, but does take some experimenting. The IBM utility doesn't allow repartitioning from the same physical drive from which the system boots (although not the same partition). A workaround would be to temporarily install a drive on IDE1 or 2 and boot with it, then partition the RAID setup as drive D and beyond...
When you get to the A: prompt, type FDISK and then choose#5 - CHANGE DRIVES so that it gets to the number 2 drive (the new one).
Then choose #1-First (Create Primary Dos Partition or Logical Drive)
Then choose #2 - CREATE EXTENDED PARTITION and use the WHOLE drive amount for that partition.
ESC key and it will ask if you want to create LOGICAL DRIVES within that Extended partition, say yes. Now, depending on how large the new drive is, you can create one complete drive with the whole space or you can create smaller partitions at this point....I would go with partitions if the drive is very large because smaller drives will scandisk and defrag faster and you have control over where you keep games, other programs, data, etc. installed). If you decide to partition, make each one about 8GB in size depending on the size of your new drive. As you create the Logical Drives keep track of the drive letters that get assigned because you will need to format them later and this way you will know which drive letters to format. The following example shows a D: drive, but yours will vary.
When you are finished with creating the logical drives, ESC back to the A: prompt and reboot again with the boot disk.
When you are at the A: prompt again, type FORMAT (DRIVELETTER): and format each of the new drives you created by typing in the drive letter for each format you type in. If the new drive letters are D: E: and F: then you would type in FORMAT D: and when it is finished then you would type in FORMAT E: etc. until all new drives are formatted. When you are finished, take the floppy disk out of the drive and boot up to the desktop. Print this so you have it handy while you are doing it rather than try to remember it all. The steps outlined will only take about ten minutes to do (except for formatting the drives) but take your time and you will do it right.
Hey, i was just wondering....after installing a second hard drive, do i need to install windows to it again? I know how to do the hardware portion, but that's got me a little confused....i am going to install my buddie's hdd, and well, i want to be sure exectly what to do so i dont look like an idiot
