External HDD not showing in iphone 14pro

Hi Team,

I have an external HDD 1 TB formatted as extFAT, when I connect to iPhone14 pro using Lightning to USB Camera Adapter it show power light but can’t see it in Files App. The same HDD if I connect to iphone15 pro using USB C type connector it working as expected.

My iphone 14 pro is 18.3.2 updated and pendrive are working as expected.

It seems like the issue lies in the power requirements or compatibility of the Lightning to USB Camera Adapter with your external HDD. Here's why this might be happening and how to address it:


1. Power Supply Limitation

- External hard drives often require more power than the Lightning to USB Camera Adapter can provide. The power light turning on indicates some power is being supplied, but it might not be sufficient for the drive to function fully.

- Use the 👉 Lightning to USB 3 Camera Adapter, which has a pass-through Lightning port for connecting an external power source. This can provide the additional power needed for your HDD.


2. Compatibility Differences

- The iPhone 15 Pro uses a USB-C connector, which generally supports higher power output and faster data transfer rates compared to the Lightning connector. This could explain why the HDD works seamlessly with the iPhone 15 Pro but not the iPhone 14 Pro.

- Ensure your HDD is formatted correctly (exFAT is supported) and has a single data partition. If the issue persists, the Lightning adapter might not fully support the HDD's power or data requirements.

Drive Not Showing Up:


Perform a Force Restart:

Leaving this plugged in, save what need be, and then perform a Force Restart of your iPhone, seeing if this shows up afterwards.
