HP does not support connecting both SATA and 3.5-inch PATA hard
drives on the same system.
Make sure to back up the data on the old hard drive before removing
it so that you can install the data onto the new hard drive.
The preinstalled 3.5-inch hard drive is located under the power
supply. To remove and replace the hard drive:
1. Turn off the computer properly through the operating system,
then turn off any external devices.
2. Disconnect the power cord from the power outlet and disconnect
any external devices.
3. Remove the computer from the stand and lay the computer on its
side.
4. Remove the computer cover. Refer to
Cover."
