Have More Than Two Hard Drives in a PC
Sometimes it feels like there can never be enough disk space. Perhaps you don’t want to delete anything on your existing drives or just want a fresh new space to keep your files organized. Unfortunately, there is only so much space inside of a computer to expand. These are some simple and low cost ways to make room and get the disk space you need.

Steps
Attaching an External Hard Drive
- Determine your best option. External drives come in many shapes and sizes to fit any user’s needs. Make sure your computer has a spare port to plug into.
- Just want to plug and play? Look for a model without an external power supply.
- Frequently backing up your data? Some models come with automatic backup software.
- Pay attention to USB speeds! Newer versions of USB will transfer data faster, but your computer must have a corresponding port. Luckily both port and cables are backwards compatible!
- Connect the external drive. External hard drives are usually connected via USB port, although some models may use external SATA. Once connected, the driver should install automatically and you can start using it to store data!
- Access the drive. Open the file explorer to verify that your drive is listed with your other storage devices. You should be able to start storing data immediately!
Mapping a Network Drive
- Determine if a network drive is right for you. Network drives are great for storing and sharing files with other users on a network. They are also useful if you want to store the drive out of the way, since they can be accessed remotely from anywhere on the network.
- Connect the drive. Network drives can be connected to your network and can be accessed like any other disk as long as you remain on the network.
- Plug in the network drive to an outlet if it requires external power.
- Connect the drive to the network. This can be done via the router or modem - usually with an ethernet or USB cable.
- Map the drive. This allows you to easily access the drive like any other hard drive whenever you are on the network. The following steps are written for Windows 10 and may vary slightly depending on the version of Windows you are running.
- Navigate to This PC > Map Network Drive.
- Select a drive letter and press Browse.
- Select the network drive from the list and press OK.
- Access your network Drive. Open the file explorer and you should see your drive appear listed with the rest of your storage devices.
Replacing the CD, DVD, or Floppy Disk Drive
- Purchase a new internal hard drive. If you don’t want to expand externally, but don’t have any extra space inside the computer, you can replace the CD, DVD, or Floppy (AKA Optical Drive). A standard 3.5” internal desktop hard drive is a good way to add lots of space for cheap.
- Both hard drives and optical drives can utilize either an IDE or SATA interface cable(two alternates to USB). Most hard drives will come bundled with the cables they need, but you may need to purchase them separately as well.
- Acquire necessary adapters. Most optical drives utilize a 5.25” expansion bay, which is too large for a 3.5” hard drive. You may need mounting brackets or a 5.25” to 3.5” bay adapter. Consult your manufacturer’s specifications to verify the size of your optical drive first.
- The expansion bay is the space that holds the drive. Both mounting brackets and bay adapters will allow you to fit your smaller hard drive into the larger space.
- Remove power from the computer. You want to make sure the computer is completely powered off and unplugged before touching any of the electronic components.
- Open the computer. You will likely need a screwdriver to open the computer wall. The type of screwdriver will vary depending on manufacturer.
- Disconnect the cables attaching the drive. Most optical drives are connected via two cables: power and data.
- The power cable typically has a white tip attached with black, yellow, and red wires.
- The data cable has a wide tip attached to a ribbon cable.
- Unscrew and remove the drive. Once the screws are removed, the drive should either slide out or release with a latch.
- Install the mounting brackets or bay adapter (if necessary). Secure the necessary adapter with screws.
- Mount the hard drive in the empty bay. Slide the drive into the bay and reattach the screws.
- Connect the hard drive to the motherboard. Reattach the power and data cables.
- Restore power to the computer. You will need to plug the computer back in to setup the drive.
- Setup the drive in the BIOS. BIOS (Basic Input/Output System) is the software used by the processor to identify its hardware like your newly installed hard drive. Different manufacturers use different software to access and modify the BIOS. Consult the manufacturer’s specifications to confirm exactly how to access the BIOS and the hardware section within.
- Power on the computer, and press the necessary key during the startup screen.
- Look for a tab named “Hardware”, “Setup” or something similar. Navigate using the keyboard.
- You should see your newly installed hard drive listed. If not, power off the computer and double check the cable connections.
- Look for an option labeled “Auto-detect” and make sure it is enabled.
- Save and Exit. This usually has a specific key bound to it in BIOS. Your computer should restart automatically.
- Format the Drive. The drive needs to formatted into a filesystem that your computer can read before it can be used. If you plan to use any Windows system files you will need to format to NTFS, but for simply storing data a filesystem like xFAT or FAT32 will be fie. The following steps are for Windows 10, but should work for other versions of Windows as well.
- Press Windows Key + R to bring up the run menu.
- Type diskmgmt.msc and press OK. This launches the disk management tool.
- Right-click the new hard drive in the list and select ‘Format…’
- Select your desired filesystem and press OK. Formatting a disk can take some time depending on the storage size of the disk. Once formatting is complete you can use your new hard drive to store data!
Tips
- Each IDE cable has two or three connectors. One end of the cable is connected to the motherboard, and the other end connects to the drives. No more than 2 drives can use an IDE channel. If you are out of connectors, you will have to install an IDE controller card. If your motherboard supports it, use the faster Serial ATA (SATA) drives instead. Many motherboards support up to four SATA hard drives (rather than the usual 2 IDE) so you can create a RAID array.
- Be mindful that other users on your network may be able to access and use your network drive. Protect your data!
- Any internal hard drive and be mounted to a matching external enclosure and used as an external hard drive.
- A smaller 2.5” laptop hard drive can be used in place of a 3.5” internal desktop drive (if you have one handy), but you will need to acquire the necessary adapters for the even smaller form factor.
- If you want to expand internally but cannot remove something from the computer to make room, you may consider acquiring a larger computer case.
Warnings
- Safety first! Always unplug the computer from the power socket before operating. Also, be sure to touch unpainted, uncoated metal before touching the computer, so that any static electricity you may have built up doesn't flow into the computer.
Things You'll Need
- An extra hard drive.
- A screwdriver. If you intend to use a method where you need to access the inside of the computer, you’ll likely need a screwdriver to open the case or remove parts. The type of screwdriver will depend on the manufacturer of the case.
- Any necessary adapters. If you plan to remove an Optical drive, you will likely need mounting brackets or a 3.5” to 5.25” adapter to fit the smaller HDD into the larger drive bay. If you plan to use a 2.5” laptop hard drive you will need a supported tray or adapter.
- A sufficiently large power supply. More hard drives means more power! Consult your manufacturer’s specifications to make sure your power supply will be able to support the extra drive.
- Available connectors for the appropriate type of drive: both power and data. There are splitters that can be purchased if you do not have enough power connectors.
- BIOS that supports the number and size of hard disks you want, unless you are creating a RAID array.
