![]() Same can be achieved using the “–type” option or in short “-t”. To remove only a specific signature you could use the “–offset” option or in short “-o”. If you want to remove the signatures and metadata of not just the entire block device but also the created partitions at once, you can do so by simply adding an asterisk to the device name. # ls -l ~/wipefs-*.bak -rw- 1 root root 8 Feb 27 18:54 /root/wipefs-sda-0x00000218.bakĪnd restore using the “dd” command. To restore first find the relevant back-up file. ![]() This can be done adding the “–backup” option or in short “-b”. You might want to create a back-up in case something goes wrong and you need to perform a restore. Note that “-a” and “-f” are the short versions of the “–all” and “–force” options, respectively. To wipe the disk /dev/sda run the following command : # wipefs -a -f /dev/sda # wipefs /dev/sda* DEVICE OFFSET TYPE UUID LABEL For this we need to add an asterisk at the end of the device name as a wildcard. Since wipefs does not work recursively running the command on an entire block device (e.g., /dev/sda), will not show the signatures of every partition on the device. # wipefs /dev/sda1 DEVICE OFFSET TYPE UUID LABEL To display the current signatures on a hard disk run the following command : # wipefs /dev/sda Removing metadata and signatures from previously used hard drives is important to ensure that when they are reused in a new system, they do not contain information that could interfere with the installation of an operating system and underlying file system and cause the process to fail. Wipefs is a great tool for removing signatures and metadata from used hard drives that have been previously partitioned and formatted.
