wipe all partitions on disk
wipefs --all /dev/sdX
wipefs can erase filesystem, raid or partition-table signatures (magic strings) from the specified device to make the signatures invisible for libblkid.
wipefs does not erase the filesystem itself nor any other data from the device. When used without any options, wipefs lists all visible filesystems and the offsets of their basic signatures.
wipefs calls the BLKRRPART ioctl when it has erased a partition-table signature to inform the kernel about the change.
