Preinstallation Considerations

Consider the following when replacing disk drives in the system unit:
v Use caution when you are handling all disk drives. Disk drives are more likely to be
damaged during installation and service than at any other time. A fall of as little as
.25 inch, bumping, or rough handling can all cause latent failures.
v Media drives are particularly sensitive to electrostatic discharge. Follow all
electrostatic-handling procedures prior to handling the media drive.
