![]() parted /dev/sdb mkpart primary fat32 1049K 15. # Now we know only 1 partition exists on /dev/sdb It was also easy, from there to create new partitions, in a straight-forward way. I found f3probe ( ) solved the problem of deleting all the partitions, quickly and easily, working with large capacity drives, and created exactly 1 partition spanning the whole drive, which was easy to delete. That deleted the partition but some partitioning software apparently found the partition backups automatically. I wanted to do the same thing (except in Slackware 14.2) but found I could not effect most of the solutions proposed here, with the most elaborate and well-documented solution creating new problems for making replacement partitions. (If you want to wipe the extended partition table, you'll need to know more about the operating system different operating systems do extended partitions in different ways.) Open up the terminal, wipe the file systems on the backing and caching device: sudo wipefs -a /dev/sda2. The primary partition table within the MBR (so, not talking about GPT here) is located 446 bytes in, so we instruct dd to seek 446 bytes in before writing.Įxtended partitions are generally created by using a primary partition slot to point at the extended partition table, so if we erase the 4 primary partitions, we effectively wipe the extended partition table as well the OS won't be able to find it, so it won't be able to read and interpret it. Boot the Raspberry Pi from the microSD card. Here, we tell dd to write 64 blocks (or bytes, because of our bs=1 parameter), since the primary partition table consists of 4 16-byte partition entries, for a total of 64 bytes. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. ![]() ![]() However, we need to address things more precisely than that, so we tell dd to use a block size of 1 byte. The default block size may be 512 bytes, 1024 bytes or 4096 bytes, depending on your system. Here, we specify which device we're writing to. Here, we specify that we're reading from /dev/zero, which is a special device which emits NUL bytes-zeros. It's the simplest flexible tool for this job. This standard command copies bytes from a source and writes them to a destination. dd if=/dev/zero of=/dev/ bs=1 count=64 seek=446 conv=notrunc Util-linux: /usr/share/man/man8/wipefs.8.If we're talking about MBR-style partitions. Or if wipefs is already installed and you need the package name % apt-file search "$(which wipefs)" wipefs does not erase the filesystem itself nor any other data from the device. Be Careful: With just a few keystrokes, wipefs can wipe out part or all of. wipefs can erase filesystem, raid or partition-table signatures (magic strings) from the specified device to make the signatures invisible for libblkid. Other examples for apt-file % apt-file search -regex "/wipefs$" Im currently trying to make my raspbian boot from a squashFS image through. util-linux: Collection of basic system utilities. To use apt_file you have to install it sudo apt-get install apt_file We know, that we search the binary, usually located in /bin, /usr/bin or /sbin, therefore your package name is util-linux and you can install it, as said with sudo apt-get install util-linux ![]() Util-linux: /usr/share/man/man8/wipefs.8.gz Util-linux: /usr/share/bash-completion/completions/wipefs Manpages-de: /usr/share/man/de/man8/wipefs.8.gz But in your case apt-file search wipefs is the better choice. Apt-cache is a good idea if you now the package name.
