This is while none of the partitions on /dev/sdb are mounted, lsblk shows. Wipefs: error: /dev/sdb: probing initialization failed: Device or resource busy I also tried: $ sudo wipefs -all -backup /dev/sdb The same command can erase filesystem, raid or partition-table signatures/metadata. When used without options -a or -o, it lists all visible filesystems and the offsets of their signatures. wipefs does not erase the filesystem itself nor any other data from the device. I/O size (minimum/optimal): 512 bytes / 512 bytesÄevice Boot Start End Sectors Size Id Type wipefs can erase filesystem or raid signatures (magic strings) from the specified device to make the filesystem invisible for libblkid. Sector size (logical/physical): 512 bytes / 512 bytes I deleted the partition and pluged the device into a Windows machine to format it from there, but the super block still sticks around: $lsblkĬhanges will remain in memory only, until you decide to write them.Ä«e careful before using the write command.Äisk /dev/sdb: 119.3 GiB, 128038469632 bytes, 250075136 sectors How to wipe a signature from a disk device on Linux with wipefs command I recently decommissioned Debian Linux based nas server and moved disk from my nas server to Linux-powered desktop. Mdadm: Couldn't open /dev/sdb1 for write - not zeroing Mdadm: Couldn't open /dev/sdb for write - not zeroing I tried: $ sudo mdadm -zero-superblock /dev/sdb When option -a is used, all magic strings that are visible. I don't need it in that array anymore (but need to add it to a different array) and hence would like to get rid of the old superblock but I can't. If the creation fails with a message that reads Device /dev/excluded by a filter, it may be necessary to wipe the disk using the wipefs command. The wipefs command (since v2.31) lists all the offset where a magic strings have been detected.I have a USB thumb drive that I briefly used in a raid 1 array.
