One of the advantages of a desktop computer like the Dell Vostro 200 slim tower is that it is easier to upgrade than a laptop. If you need additional space, or a spot to back up your important files, you can install a second hard drive in your Vostro. You do not have to pay a professional computer technician to do the upgrade. With a few tools and some time, you can upgrade the Vostro on your own and start enjoying all that extra storage space.
Shut down the Dell Vostro 200 and remove anything attached to it. Lay the computer on its side with the case facing up.
Remove the two screws that secure the computer cover. Set those screws aside, then pull the cover forward and lift up to remove it.
Lift the tabs that connect the front bezel to the computer to release them. Lift each tab one at a time, then pull the bezel away from the computer.
Lift the card retention bracket at the back of the computer. Remove the cable securing the support bracket, then pivot the bracket up and remove it from the PC.
Locate an empty drive bay in the Dell Vostro 200. Slide the new hard drive into the bay and attach the shoulder screws to hold it in place. Attach one end of the drive cable to the back of the hard drive and the other end to the secondary hard drive slot on the system board.
Extend a power cable from the power supply to the power port on the back of the new hard drive. Place the support bracket back in place and replace the computer cover.
