Drives
A Torx T-15 screwdriver is needed to remove and install the guide screws on a drive.
CAUTION: Make sure personal files on the hard drive are backed up to an external storage device
before removing the hard drive. Failure to do so will result in data loss. After replacing the primary hard
drive, you will need to run the Restore Plus! CD to load the HP factory-installed files.
