Your TV doesn't recognize USB drives with movies? Here's how to fix that problem in a minute
When you connect a USB drive to your TV and get a message that the device is not recognized, the problem is almost always the wrong file system. Most new drives come with factory settings that modern operating systems on TVs like Hisense or Samsung often do not support. The solution lies in a process called formatting, which aligns your drive's "language" with the TV's software.
TL;DR
- TVs often don't recognize USB drives because of incorrect file systems, usually the older FAT32.
- FAT32 has a 4GB limit for individual files, insufficient for large HD movies.

- External hard drives with large capacities may require a separate power supply.
