What a technician must be able to justify
A technician is coming
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

What they doPlayStation, the publisher, network provider or retailer should reproduce the exact USB device model and required format, PS4 model, port, normal-versus-Safe-Mode result and whether the fault follows the device before paid account work, repair or replacement.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Freeze the first exact failure
Photograph CE-30784-2 and the complete message. Record PS4 model, system version, account/store region, affected title or device, storage/network path, timestamp and failed operation. Redact account and payment data.
Power off before reconnecting hardware. Do not open the console or accessory, force connectors, use unsupported adapters or buy a replacement until the fault follows a tested item.

Run one discriminating check
Power the PS4 fully off, reconnect the supported USB device once and test another compatible port. Compare the device on a computer or use one known-good supported device if available; do not format it until required data is copied elsewhere.
Power off before reconnecting hardware. Do not open the console or accessory, force connectors, use unsupported adapters or buy a replacement until the fault follows a tested item.
Evidence: Official PS4 error codes
Stop at the evidence boundary
A fault that follows the USB device selects compatibility, format or the device; one PS4 port or Safe-Mode-only failure selects the console path. Recognition elsewhere disproves a globally dead drive. If the same result returns after one controlled pass, do not chain resets, deletion, retries or purchases.
Power off before reconnecting hardware. Do not open the console or accessory, force connectors, use unsupported adapters or buy a replacement until the fault follows a tested item.
