Internal drive installation - ThinkCentre 8198, 8199

Information and instructions for installing and removing internal drives.

Internal drives are devices that your computer uses to read and store data. You can add drives to your computer to increase storage capacity and to enable your computer to read other types of media. Some of the different drives that are available for your computer are:

  • Hard disk drives
  • CD drives or DVD drives
  • Removable media drives

Note: These different drives are also referred to as integrated drive electronics (IDE) drives.

Internal drives are installed in bays. The bays are referred to as bay 1, bay 2, and so on. When you install an internal drive, it is important to note what type and size of drive that you can install in each bay. Also, it is important to correctly connect the internal drive cables to the installed drive.

Drive specifications:
Your computer might come with the following installed drives:

  • A CD drive or DVD drive in bay 1 (some models)
  • A 3.5-inch diskette disk drive in bay 3
  • A 3.5-inch hard drive in bay

Note: Any bay that does not have a drive installed has a static shield and bay panel installed.

The following illustration shows the locations of the drive bays.
