Removing a Hard Drive from the Rotatable Carrier (Tower or Desktop Computer)
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.
CAUTION: To guard against electrical shock, always unplug your computer from the electrical outlet before opening the cover.
NOTICE: To prevent static damage to components inside your computer, discharge static electricity from your body before you touch any of your computer’s electronic components. You can do so by touching an unpainted metal surface on the computer.
NOTICE: To avoid damage to the hard drive, do not set it on a hard surface. Instead, set the drive on a surface, such as a foam pad, that will sufficiently cushion it.
1If you are replacing a hard drive that contains data that you want to keep, back up your files before you begin this procedure.
2Follow the procedures in "Before You Begin" on page 151.
