![]() Hopefully, after that, your first drive will be working like a new one. So, when everything is finished successfully and there were no errors, you can create a new partition table on your flash drive and format it with the FAT filesystem as I showed above. And if your flash drive is big it takes a really long time. Also, writing zeros to a flash drive takes quite a lot of time. ![]() Note: Again, make sure that this is the name of your flash drive. But in this command, you do not need to specify any number, you need to provide the name of a drive, which is sdb. In the unmount command, I used sdb1 because it was a partition. Other option to format a bootable USB to normal This is due to incorrect partitioning when a bootable flag is added to a USB flash drive. For example, you copied some files there and they disappear or you can connect your flash drive to Linux but it does not work on Windows. One more solution to format a bootable USB to normalĪfter installing Linux from a bootable USB, the USB drive is likely not to work correctly.Create the partition using a graphical tool.Create the new partition using the command line.Wipe the filesystem from your flash drive.Find the name of the device in the Terminal.You can also use this method to recover any other USB flash drive which stopped working or does not work correctly Content This post will help you to format a bootable USB drive to normal. The flash drive just misbehaves and you do not know what to do. ![]() dd if=~/wipefs-sdb-0x00000438.bak of=/dev/sdb seek=$((0x00000438)) bs=1Ĭonv=notrunc Restores an ext2 signature from the backup fileĮNVIRONMENT ¶ LIBBLKID_DEBUG=all enables libblkid debug output.You have finally installed your Linux from a bootable USB flash drive. EXAMPLES ¶ wipefs -all -backup /dev/sdb Erases all signatures from the device /dev/sdb and creates a signatureīackup file ~/wipefs-sdb-.bak for each signature. V, -version Display version information and exit. Prefixed with 'no' to specify the types on which no action should be t, -types list Limit the set of printed or erased signatures. q, -quiet Suppress any messages after a successful signature wipe. Unsafe characters of a string to the corresponding hex value prefixed by p, -parsable Print out in parsable instead of printable format. "K" has the same meaning as "KiB"), or the suffixes GiB, TiB, PiB, EiB, ZiB and YiB (the "iB" is optional, e.g. Multiplicative suffixes KiB (=1024), MiB (=1024*1024), and so on for The offset argument may be followed by the Prefix then the number will be interpreted as a hex value. o, -offset offset Specify the location (in bytes) of the signature which should be erasedįrom the device. n, -no-act Causes everything to be done except for the write() call. Order to erase a partition-table signature on a block device. f, -force Force erasure, even if the filesystem is mounted. For more details see theĮXAMPLES section. b, -backup Create a signature backup to the file OPTIONS ¶ -a, -all Erase all available signatures. ![]() Note that by default wipefs does not erase nested partition When option -a is used, all magic strings that are visible Still be visible because of another magic string on another offset. ![]() It is possible that afterĪ wipefs -o offset the same filesystem or partition table will The device is not scanned forĪdditional magic strings for the same filesystem. Offset where a magic string has been detected. Note that some filesystems and some partition tables store more Partition-table signature to inform the kernel about the change. Wipefs calls the BLKRRPART ioctl when it has erased a Visible filesystems and the offsets of their basic signatures. When used without any options, wipefs lists all Wipefs does not erase the filesystem itself nor any otherĭata from the device.
