Raid metadata

Como remover informações de BIOS RAID metadata do disco

When I installed CentOS on a used disk, it gave me an error message: “Disk contains BIOS metadata, but is not part of any recognized BIOS RAID sets. Ignoring disk sdb”

[root@localhost ~]# dmraid -r -E /dev/sdc
Do you really want to erase “pdc” ondisk metadata on /dev/sdc ? [y/n] :y
