The most common cause is a bad or wrongly connected HDD, with other factors including damaged drive data, loose SATA connections, or a damaged motherboard connection.
1. Reinstall the Hard Disk Drive
When encountering the CE-34335-8 error code, the first step is to reinstall your PS4’s existing hard drive. A slightly misaligned drive can prevent the system from detecting it.
2. Replace Hard Drive
If reinstalling the hard drive doesn’t solve the issue, the drive is likely faulty and needs to be replaced. This process has three parts: downloading the latest PS4 system software to a USB drive, replacing the hard drive, and reinstalling the system software in PS4 Safe Mode. Follow the instructions below.
2.1. Download Latest System Software
2.2. Replace the Hard Drive
2.3. Install System Software
