320MB equals 298GB formatted as measured by the PS3. (32,000,000.00/1,073,741.824) = 298
If you have access to an external USB HDD (fat32 format), it's best to create a back up of your HDD image (System Settings - Backup Utility - Back Up), which will archive everything down to your game saves. It's good to have a back up anyway in the instance that something kills your HDD, but not too many people do this for some reason.
If not, back up your game saves on a USB thumb drive. It's tedious if you have a lot of saves. You'll have to re-download all your PSN games and demos again.
You can pop the HDD marked cover with a fingernail. Won't scratch.
The blue caddy lock screw can be a bit sticky (it's coated and machine tightened), leading to a stripped head if you use the wrong size driver.
A #1 Phillip's found in electronics screwdriver sets fits perfectly, but you may have to use a set of toothed pliers to provide the torque leverage. Just keep pressure on the screwdriver by pushing it into the screw head while applying torque with the pliers. It doesn't take much force with the pliers before you hear a slight crack as the screw loosens.
Use the same technique to loosen the four caddy screws holding the HDD in place to avoid stripping the screw heads.
Any S-ATA 2.5" drive should fit. Best drives to use in terms of reliability are widely accepted as Seagate and then WD. The OEM 60GB HDDs were Seagate Momentus drives.
Once the replacement drive's in the PS3, upon boot up, it will prompt you twice to reformat the drive, after which, it will restart and all your games, saves, demos, video/media will be gone. The latest firmware update is on flash ROM, and will still be present.
Go back to System Settings - Backup Utility and click Restore once your backup external USB HDD is plugged in and all your data from your original drive will be on your new drive.
Best way to swap drives is with a Backup archive on external drive. Keep the backup archive in case anything goes wrong and you reformatted the original HDD.
