Please check it:
Control Panel, Administrative Tools, Computer Management (please run as administrator; right click it), Disk Management. What is the information of your 1 TB hard drive? Is there any unallocated space?
Testimonial: "It says there is 335.34GB unallocated."
Here is a screen shot.
Basically, there is an unused 335.35GB, so you can format it and create a new drive letter, or you may merge it with its existing allocated drive (try to drag the border between blue and black to the right).
or when you click on the blue area (next to the unallocated area), and right click it, you will see "extend volume". You can try to increase the number and see if the system allow you to change the allocated space using this method.
All fine now, thanks very much

Go into My Computer, look for the drive.
Right click on the Drive, click on Create Shortcut you will be asked if you wish to place shortcut on the Desktop instead. click yes.
A new ICON will appear on the desktop, to access the new drive you only have to click the ICON of the drive and it will open....

One or more of the hints below will probably sort out most USB problems with most USB portable / external hard drives and OTHER devices (though not always)
A few things to check but assumes USB and Windows for other interfaces / operating systems (mac/ Linux) similar steps may be adapted to suit.
1. Ensure it is connected directly to the computer to a USB 2.0 port not a USB 1.0 port as this can have effects on performance and reliability
2. Use only the cables that came with it NOT one that fits that may have been lying around or is longer. Not all USB cables are equal even though they should be)
3. Do not connect through an external USB HUB unless that hub is USB 2.0 AND has its own power supply.
4. Use ONLY the power supply that came with it if it has an external power supply Don’t use any other unless you know it has both the same voltage and current rating e.g. 12V 500mA anything rated below that would not work properly. 5. Always use the same port for connecting your devices. Some devices do not like being switched about. If switched they may want to install software / drivers again. This can be especially true if you move a HUB to another port
6. For FLASH DRIVES you should ensure that the device is set for "quick removal" using the drive control panel properties or use the USB "Safely Remove Hardware" option. If you dont do this there is a very strong chance that any files you transfer may not be there when you plug into another computer.
7. It is possible to remove drives from the enclosures in most cases and connect directly inside a PC to fully check it.
You should also do this to cheack the drives connections are not bad inside the enclosure.
8. If none of the above steps help look at updating the drivers from the manufacturers web site in the support section.
9. If you checked and fixed anything there and still have issues then check your hardware from CONTROL PANEL / SYSTEM / HARDWARE.
Any exclamation marks by hardware need fixing before you investigate any further
10. ensure that you have set removable drives for "quick removal" or that you use the "Safly Remove Hardware" option often shown on the lower toolbar.It is possible that files my not be fully written to external devices before they are removed. This corrupts the file itself and even on occasion the drive.

perhaps the new hard drive is bad western digital software is junk take it back and get seagate external w/freeagent on it

I have a similar drive but I have not had this problem so far.
First the obvious: Make sure everything is plugged in securely (power, USB). Try the drive with other computers to make sure the problem isn't
just your own system. If your device works fine, keep reading, if not, go to the last paragraph.
If you're sure everything is secure, go into your Device Manager (Windows Logo key + R and enter "devmgmt.msc") and look under "Disk drives". You SHOULD see a drive in there that looks something like "WD MyBook _____ USB Device".
If the drive is in there, try uninstalling that device and unplug and plug your drive in. Windows should recognize the drive and reinstall the drivers needed for it.
If this doesn't fix the problem, scroll down to "IDE ATA/ATAPI controllers". Do the same thing uninstall-unplug-plug in deal with "Standard AHCI1.0 Serial ATA Controller".
If this does not fix the problem, or if you don't see either device in your device manager and your drive does not work on another computer, you MAY be in possession of a faulty drive. Do a warranty check to make sure you're still eligible for WD Warranty Services: http://support.wdc.com/warranty/index_end.asp?lang=en. From there you can do a status check, have your hard drive replaced or repaired, or request email support from the makers of your hard drive.
Best of luck!
SOURCE: My 1 tb WD hard drive isn't even being recognized
do you have 2 usb cables coming out of the drive
make sure you have plugged both in to usb ports
and you mentioned your computer is old htere is a possibility you might have usb1.1 ports which doesnt support 1tb external hard drives
use this guide to chek your usb version

Hard drive manufacturers market drives in terms of decimal (base 10) capacity. In decimal notation, one megabyte (MB) is equal to 1,000,000 bytes, one gigabyte (GB) is equal to 1,000,000,000 bytes, and one terabyte (TB) is equal to 1,000,000,000,000 bytes.
Programs such as FDISK, system BIOS, Windows, and MacOS use the binary (base 2) numbering system. In the binary numbering system, one megabyte is equal to 1,048,576 bytes, one gigabyte is equal to 1,073,741,824 bytes, and one terabyte is equal to 1,099,511,627,776 bytes.
Simply put, decimal and binary translates to the same amount of storage capacity. Let's say you wanted to measure the distance from point A to point B. The distance from A to B is 1 kilometer or .621 miles. It is the same distance, but it is reported differently due to the measurement.
Capacity Calculation Formula
Decimal capacity / 1,048,576 = Binary MB capacity
Decimal capacity / 1,073,741,824 = Binary GB capacity
Decimal capacity / 1,099,511,627,776 = Decimal TB capacity
Example:
A 500 GB hard drive is approximately 500,000,000,000 bytes (500 x 1,000,000,000).
500,000,000,000 / 1,048,576 = 476,837 megabytes (MB) = 465 gigabytes (GB)
