Removing and 
Replacing Drives 
Your PC has several drives that you can replace or 
upgrade. You can add a drive into an empty drive 
bay. See the preceding topic, “Locating Components 
Inside the PC,” for drive type and location. For hard 
disk drives, see “Removing a Hard Disk Drive“ on 
page 5. 
IMPORTANT: Before adding a new diskette drive, 
memory card reader, optical drive, or hard disk drive, 
make sure that it is compatible with the Microsoft®
Windows®XP operating system. Also, make sure you 
have the correct software and drivers for the drive to 
work with the operating system. 
Removing a Drive 
1 Complete the procedures to prepare the PC, to 
remove the side panel, and to remove the front 
panel. See “Opening and Closing the PC“ on 
page 1. 
2 Locate the drive you want to remove. 
3 Disconnect the power cable (1) and data cable (2) 
from the back of the drive you want to remove, as 
indicated in the following illustrations. Use a gentle 
rocking motion. Some units may have a sound 
cable. If so, disconnect the sound cable (3).
