What causes the SU-30746-0 software update error on PS4?

Your PlayStation 4 may experience issues during software updates for a variety of reasons. To learn more about what may be contributing to this error, read below:

1. Hard Drive Failure

The PS4 has a traditional mechanical hard drive, an HDD. These are somewhat more unreliable and can experience early failure due to a head crash or other problems. If you are experiencing freezing or issues during updates, check for these symptoms that may suggest hard drive failure:

  • Frequent crashes
  • Overheating or excessive noise coming from PS4
  • Read or Write disk errors
  • PS4 error CE-34335-8 (no hard drive) 
  • Date corruption
  • Booting into Safe Mode
Failed Hard Drive

If you are experiencing a few of the symptoms listed above and the SU-30746-0 error, you may need to backup your HDD as soon as possible. A critical hard drive failure could render data retrieval impossible.

2. System Software Problems

The PlayStation 4 has software that runs all the major services and tasks for your PS4. This software is responsible for communicating with the PS4 hardware and managing the system’s memory and processes. If the PS4 system software is corrupt, then problems are likely to arise, such as freezing or stuttering. You can solve software corruption issues by fully initializing your PS4, which will reinstall the system software. 

3. Database Issues

Database issues can trigger error codes during software updates. Your database itself may be corrupted or just the data itself. Suspect a database issue if you encounter problems like:

  • Sputtering graphics and sound, including frame-rate drops
  • Error code CE-34875-7
  • Error code NP-32062-3
  • Slow load times
  • Issues reading game disks

You can resolve many database issues by restarting your PS4, but you can also defragment your drive.
