Reconnect the drive straight to the console
- Who:
- you.
- How:
- unplug the USB cable and plug it back in fully. If you use a USB hub, remove it and connect the drive directly to the PS5.
- Result that matters:
- the console recognizes the drive with nothing in between.
- If it recognizes it:
- the fault was a loose cable or the hub.
- If it still does not:
- try another port.
- Evidence to keep:
- Whether there was a hub and which port it used.

Try another USB port
- Who:
- you.
- How:
- connect the drive to another PS5 port. For extended storage, Sony names the USB Type-C or Type-A SuperSpeed USB 10 Gbps port.
- Result that matters:
- you learn whether the fault depends on the port.
- If it works in another port:
- the first port is failing and the drive is fine.
- If it works in none:
- the problem points at the drive.
- Evidence to keep:
- Ports tried and the result in each one.

Try another drive and check requirements
- Who:
- you.
- How:
- connect another USB drive. If it is used as extended storage, check that it is SuperSpeed USB 5 Gbps or later and 250 GB to 8 TB, and that two extended storage drives are not connected at once.
- Result that matters:
- you learn whether the console recognizes another drive.
- If it recognizes the other one:
- the first drive is unsupported or failing.
- If it recognizes none:
- the problem is on the console side.
- Evidence to keep:
- Model, capacity and connection type of each drive.

Reinstall the application that triggers the error
- Who:
- you.
- How:
- if the error only shows while one application runs, go to Settings > Storage > Console Storage > Games and Apps, delete it and reinstall it from your library.
- Result that matters:
- the drive is recognized with that application reinstalled.
- If it is recognized:
- the application was the cause.
- If it fails with any application:
- go back to the port and drive tests.
- Evidence to keep:
- Application name and date of the reinstall.

What it means
CE-109737-7 means the console does not detect the connected USB drive. Sony's steps separate four areas: the physical connection (cable not fully in or a USB hub), the port used, the drive itself (whether another drive is recognized) and a specific application that triggers the fault. For extended storage Sony requires SuperSpeed USB 5 Gbps or later, 250 GB to 8 TB, with no hub. The code does not prove a console port is faulty.
