Hi @Firminou

The USB has a number of partitions added to it with its flashed with Balena. You need to delete those and then repartition as a single partition in whatever format you require.

Windows:

Linux:

Deleting all partitions on a USB drive using fdisk

Mac:
Disk Utility

Just take care to make sure you are deleting the right partitions off the right devices.

Cheers
