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. . 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. 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. 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).  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. M.2 SSDs come in a variety of sizes.  This size of the drive is coded using a 4 digit number.  For example, a 2280 M.2 drive is 22x80 mm, and a 2260 M.2 device is 22x60 mm.  In order to install an M.2 SSD, you'll need to see if your motherboard has an M.2 connector slot, and what size SSD the motherboard supports.  2280 is the most common size for desktop computers.  You'll also need to check if the M.2 connector slot on your has an M or B key slot.  An M.2 SSD with an M key slot will not fit in a B key connector.  Check the manual for your motherboard and make sure the M.2 SSD you purchase is compatible with your motherboard.    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. To shut down your computer, click the Windows Start icon, and then click 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. 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. . 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. . If you are removing an old hard drive, make sure any and all cables are disconnected from both the motherboard and the power supply. If the hard drive is screwed in, remove all the screws. You may need to remove more cables or cards in order to access the hard drives in a tight case. Some computers use a special enclosure to secure the hard drive.  If your hard drive has an enclosure for the hard drive, 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. Place the hard drive in the hard drive slot the old hard drive was housed in, or the expansion slot for a new hard drive. Once the hard drive has been inserted, use the screws that came with it to secure the hard drive in the housing. 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. 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.  To install an M.2 SSD, simply insert the SSD into the M.2 slot at a 30-degree angle.  Press down on the other end of the SSD and screw it to the motherboard. 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 for your motherboard. 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. Replace the case sides and reconnect your cables if you had to move the case to work on the inside. 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. . Empty hard drives require an operating system to be installed on them before you can use your computer again.
