wipefs

Wipe filesystem, raid, or partition-table signatures from a device. More information: https://manned.org/wipefs.

• Display signatures for specified device:

sudo wipefs {{/dev/sdX}}

• Wipe all available signature types for a specific device with no recursion into partitions:

sudo wipefs --all {{/dev/sdX}}

• Wipe all available signature types for the device and partitions using a glob pattern:

sudo wipefs --all {{/dev/sdX}}*

• Perform dry run:

sudo wipefs --all --no-act {{/dev/sdX}}

• Force wipe, even if the filesystem is mounted:

sudo wipefs --all --force {{/dev/sdX}}
