Roku Error Code 019 — What It Means & How to Fix It

What Does This Error Mean?

Roku error 019 means there is a problem with a USB device connected to your Roku. The device cannot read the USB drive or the files on it. This is usually caused by an incompatible format, a faulty drive, or an unsupported file type.

Affected Models

Roku Ultra
Roku Express 4K Plus
Roku Streaming Stick 4K Plus

Common Causes

The USB drive is formatted in a file system Roku does not support (like NTFS or exFAT)
The media files on the USB drive use a codec or format that Roku cannot play
The USB drive is drawing too much power and the Roku port cannot supply enough
The USB drive is physically damaged, corrupted, or failing
The USB drive was not safely ejected from a computer before use

How to Fix It

Unplug the USB drive from the Roku, wait 10 seconds, then plug it back in firmly. A loose connection can cause this error.

Make sure the drive clicks or sits firmly in the USB port.
Check the USB drive format on a computer. It must be formatted as FAT32 for Roku to read it. NTFS and exFAT are not supported.

On Windows: right-click the drive in File Explorer > Properties > look for 'File System'. Reformat to FAT32 if needed — this will erase all files on the drive.
Check that your media files are in a supported format. Roku supports MP4, MKV, MP3, AAC, JPEG, and PNG. Other formats may not play.

You can convert unsupported files using free software like HandBrake before copying them to the drive.
Try a different USB drive to test whether the problem is with the drive or the Roku. Use a simple, small drive formatted as FAT32.

If a different drive works, your original drive is the problem.
Avoid using USB hubs. Connect the drive directly to the Roku's USB port. Hubs can reduce the power available to the drive.

Powered USB hubs are an exception — they supply their own power and usually work fine.

When to Call a Professional

If multiple USB drives show error 019 on your Roku, the USB port on the device itself may be damaged. Contact Roku support with your device model and serial number. A damaged USB port usually means the device needs to be replaced.

Frequently Asked Questions

What file formats does Roku support on USB?

Roku supports common video formats like MP4 and MKV, audio formats like MP3 and AAC, and image formats like JPEG and PNG. Less common formats such as AVI or WMV may not be supported. Check Roku's official site for the full list.

How do I reformat a USB drive to FAT32 on Windows?

Plug in the drive, open File Explorer, right-click the drive, and choose Format. Select FAT32 from the file system dropdown and click Start. Warning: this erases everything on the drive — back up your files first.

Does Roku support external hard drives, or only USB sticks?

Roku can work with small external hard drives, but they must be self-powered or bus-powered drives within the Roku's USB power limit. Large hard drives that need their own power adapter may not work reliably.
