How do you define safely? It means the entire MBR record is invalid, including the partition scheme. # wipefs -a /dev/sdb Will do exactly the above on MBR disks, it removes the MBR signature making it invalid. If the GPT partition scheme is used, wipefs will remove the GPT primary and backup header signatures, and the PMBR signature, making all three of them invalid and thus not a partitioned drive. -- Chris Murphy -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
