Back Up Your Hard Drive
Connect a USB flash drive to a USB port on the PS3.
Turn on the PS3 and go to "Settings."
Select "System Settings."
Choose "Backup Utility." Three options appear. Choose "Back Up."
Choose "Yes" to confirm you wish to back up your data to an external device.
Choose the USB device. The PS3 backs up your data to the USB flash drive. After you install your new hard drive, you can load your old data.
Install New Hard Drive
Turn off the PS3 and remove the hard drive bay cover by pulling it off the side of the console. You can gain leverage by working the Phillips screwdriver beneath the cover's hinge.
Unscrew the blue screw, located on the hard drive's holder, using the Phillips screwdriver.
Grab the metal latch on the hard drive case, slide it toward the front of the console and then pull it out of the PS3.
Use the Phillips screwdriver to remove the four screws on the hard drive case.
Slide the hard drive out of the case.
Slide your new hard drive into the case then reverse install everything back into place.
Load the backup utility again, but instead of choosing "Back Up" when the three options appear, choose "Restore" to load your old data onto the new hard drive.
