You can purchase an electronics screwdriver kit from any major retailer. Method 1 Installing a hdd Drive in a Desktop 1 Make sure that you're using a Windows computer. While it's technically possible to replace an iMac hard drive, doing so is incredibly difficult and could void your warranty. Windows desktop computers, on the other hand, tend to be fairly easy to tinker with. • If you want to install a hard drive on a Mac computer, you can take it to an Apple professional and have them help you. 2 Back up your computer's data. If you're removing an existing hard drive from your computer, back up its information so that you can restore the information later. • If you want to keep your original hard drive installed, consider adding a second hard drive instead. Alternatively, you can clone an existing hard drive to a newer one. • You can back up your data using another hard drive or external device, or using a cloud storage service, like Google Drive, iCloud, Dropbox, or OneDrive. 3 Make sure you are able to install a hard drive on your computer. Before you go purchasing a new hard drive for your computer, make sure you are able to install a new hard drive on your computer. If you want to install a second hard drive on your desktop PC, make sure it has an expansion slot that allows you to install a second hard drive. If you have an all-in-one PC monitor, make sure the hard drive inside the monitor is replaceable. 4 Buy a hard drive that is compatible with your desktop motherboard. SATA is the most common hard drive type for modern computers, though many newer motherboards support M.2 SSD hard drives, which are much smaller and often faster than SATA drives (if the drive and your motherboard support NVMe).[1] • SATA drives come in two sizes. 3.5 inch (8.9 cm) SATA drives are used in most desktop computers. All-in-one PC monitors may require a 2.7 inch (6.9 cm) SATA drive. • Solid State Drive (SSD) vs. Hard Disk Drive (HDD): Hard Disk Drives are mechanical disk drives. They are usually slower, but less expensive. Solid-state drives have no moving parts. They are much faster, quieter, and more expensive. You can also purchase a hybrid HDD/SSD drive. 5 Shut off and unplug your computer. To shut down your computer, click the Windows Start icon and the power icon in the Start menu. Click Shut Down to turn off your computer. You can also press and hold the power button on your laptop keyboard, or desktop PC tower to shut down your computer. Unplug your computer and press the power button to exhaust any residual electricity in the computer electronics. 6 Ground yourself. This will prevent electrostatic shock from damaging the components of your computer. You can ground yourself by touching something metal while you work, or purchasing static wrist bands that you wear while you work inside your computer. 7 Remove your computer panel. You will most likely need a Phillips screwdriver. Remove the side panel of the computer tower. You may need to remove both sides of the computer tower. 8 Remove the old drive. The way a hard drive is mounted varies from one computer case to the next.[2] If you are removing an old hard drive, make sure any and all cables are disconnected from both the motherboard and the power supply. You may need to remove more cables or cards in order to access the hard drives in a tight case. • Drive Bays: Some computer cases have a drive bay that you slide the hard drive into and then secure it by fastening it to the chassis with screws. If this is the case, remove the screws and then slide the hard drive out of the drive bay. • Drive Cages: In some computer cases, the hard drive is mounted to a metal or plastic drive cage that is then inserted into the computer case. The hard drive may be secured to the drive cage using screws, or it may be a toolless drive cage that uses pins and clips that fasten to the hard drive. If your computer case uses a drive cage, remove the screws or detach the clips that secure it to the computer chassis, and then slide the cage out with the hard drive inside. 9 Transfer the drive cage to the new hard drive (if present). If your computer case uses a drive cage, remove all the screws and pull the old hard drive out. Place the new hard drive in the same enclosure and secure it with the screws. If you have a toolless drive cage, pull the sides away from the hard drive to unfasten it, and then slide the hard drive out of the drive cage. 10 Secure the hard drive. Once the hard drive has been inserted, use the screws that came with it to secure the hard drive in the drive cage. Ideally, you should use two screws on each side of the hard drive. If the hard drive is loose, it can rattle and cause more noise and lead to physical damage. • Tighten the screws to a firm tightness but don't over-tighten as that may cause damage as well. • If you are using a toolless drive cage, make sure the hard drive is securely fastened to the clips and pins of the mounting bracket. 11 Slide the hard drive back into the case. Go ahead and slide the hard drive back into the hard drive bay in the computer chassis. If needed, secure it using screws. 12 Attach the drive to the motherboard. Newer hard drives will use SATA cables, which are thin and resemble USB cables. Use a SATA cable to connect the hard drive to the motherboard. SATA cables can be connected in either direction. • If you are connecting your primary hard drive, the SATA cable should be plugged into the first SATA channel. This may be labeled SATA0 or SATA1. Refer to your motherboard documentation for detailed information on your motherboard. 13 Connect the power supply to the hard drive. Most newer power supplies have SATA power connectors, though older power supplies typically only have Molex (4 pin) connectors. If this is the case, and you are installing a SATA drive, you will need a Molex-to-SATA adapter. • Ensure that none of the cables can come undone by wiggling them a little bit. 14 Close up your computer. Replace the case sides and reconnect your cables if you had to move the case to work on the inside.[3] 15 Plug in your computer and power it back on. You should hear the hard drive begin to spin up. • If you hear beeps or any jarring noises, immediately turn off the computer and check the hard drive's connections. 16 Format the hard drive. If you are installing a new primary hard drive, you will need to install Windows. If you are installing the new hard drive as a secondary drive, you will need to format the new hard drive. Use the following steps to do so on Windows:[4] • Right-click the Windows Start menu and click Disk Management. • Locate the new hard drive. It will probably be listed as "Unallocated." • Right-click the new hard drive and click New simple volume. • Click Next in the dialog box. • Leave the drive space as it is and click Next. • Enter a new drive letter (or leave it as it is) and click Next. • Click Next and then click Finish. It is important to note that formatting and partitioning an HDD will erase all existing data on the drive, so it is important to back up any important data before proceeding. Practical 4 Understand layout, characteristics and functions of different components of Hard Disk Drive (HDD) as a storage device The components of a Hard Disk Drive (HDD) include: 1. Platters: These are the circular disks that are coated with a magnetic material. Data is stored on the platters in the form of magnetic patterns. A typical HDD can have multiple platters stacked on top of each other. 2. Read/Write Heads: These are small electromechanical devices that are used to read and write data on the platters. The read/write heads move back and forth across the platters, reading and writing data using magnetic fields. 3. Actuator Arm: This is an arm that holds the read/write heads and moves them across the platters to access the data. 4. Voice Coil: The voice coil is responsible for moving the actuator arm and the read/write heads. It works on the principle of electromagnetic induction, where a current is passed through a coil of wire, creating a magnetic field that interacts with the permanent magnet on the actuator arm, causing it to move. 5.

Practical 6 Install and understand the working of printer A printer is an output device that prints text or graphics on paper or other print media. There are various types of printers available, but the most common ones are inkjet printers and laser printers. Inkjet printers work by spraying tiny droplets of ink onto the paper through a print head that moves back and forth across the page. The ink cartridges contain different colored ink, and the printer mixes these colors to create the desired color output. The print head moves across the page in a series of horizontal lines, laying down ink droplets as it goes, until the entire image or document has been printed. Laser printers, on the other hand, use a toner cartridge that contains a powder made up of tiny particles of toner. The printer heats up the toner particles and transfers them onto the paper in the form of an electrostatic charge. The toner is then fused onto the paper using heat, resulting in a high-quality printout. Before printing, the user sends the document to be printed to the printer through a cable or wireless connection. The printer receives the data and converts it into a format that can be understood by the print head or toner cartridge. The printer then prints the document by moving the print head or toner cartridge across the page and depositing ink or toner onto the paper. In summary, a printer works by receiving digital data from a computer, converting it into a printable format, and then depositing ink or toner onto paper or other print media to create a physical copy of the document or image.
