Connecting and Disconnecting Drive Cables
When removing an IDE drive data cable, grasp the colored pull tab and pull until the connector
detaches.
When connecting and disconnecting a serial ATA data cable, hold the cable by the black connector at
each end.
Like IDE connectors, the serial ATA interface connectors are keyed for correct insertion; that is, a notch
or a missing pin on one connector matches a tab or a filled-in hole on the other connector.
Hard Drive
CAUTION:
Before you begin any of the procedures in this section, follow the safety instructions located in the
Product Information Guide.
CAUTION:
To guard against electrical shock, always unplug your computer from the electrical outlet before
removing the cover.
NOTICE:
To avoid damage to the 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.
NOTICE:
If you are replacing a hard drive that contains data you want to keep, back up your files before you begin
this procedure.
Check the documentation for the drive to verify that it is configured for your computer.
Removing a Hard Drive
1 Follow the procedures in "Before You Begin" on page 53.

Since the following steps do not require the complete removal of the DVD drive and the floppy drive, it is not
necessary to disconnect the cables connecting the two drives.
2 Remove the DVD drive from the bay and carefully set it aside.
3 Remove the floppy drive from the bay and carefully set it aside.
