Linux use tips 5--format USB flash drive

Generally speaking, formatting a partition of the USB stick is very simple, only need to use the MKFS command to specify the target file system, the example is as follows:

sudo-lsudo mkfs -t vfat /dev/sdb1

The-t parameter is the destination file format, the others are Ext3,msdos, and the default is ext2.
We can also do this with the following simple commands:

Mkdosfs(8),MKE2FS(8),MKFS.BFS(8),MKFS.ext2(8),MKFS.ext3(8),MKFS.Minix(8),MKFS.Msdos(8),MKFS.VFAT(8),MKFS.XFS(8),MKFS.Xiafs(8)

After the Linux use Tip 3 is made into the system boot disk, the USB stick is actually divided into two partitions.

$ sudo fdisk-l ... DISK/DEV/SDB:4009MB,4009754624 bytes -Heads +Sectors/track,3824Cylinders, Total7831552Sectorsunits = Sectors of 1* += + bytesSector size (logical/physical): + bytes/ + bytesI/O size (minimum/optimal): + bytes/ + bytesDisk identifier:0x7680fe3eDevice Boot Start End Blocks Id system/dev/sdb1 *0     2611199     1305600    -Hidden HPFS/NTFSDISK/DEV/SDB1:1336MB,1336934400 bytes -Heads +Sectors/track,1275Cylinders, Total2611200Sectorsunits = Sectors of 1* += + bytesSector size (logical/physical): + bytes/ + bytesI/O size (minimum/optimal): + bytes/ + bytesDisk identifier:0x7680fe3eDevice Boot Start End Blocks Id SYSTEM/DEV/SDB1P1 *0     2611199     1305600    -Hidden Hpfs/ntfs

This will hide a large part of the space, only the format of/DEV/SDB1 is not enough. Also format the/DEV/SDB so that the entire USB stick is formatted. But here's a problem:

-t vfat /dev/sdbmkfs.3.0.9 (312010)mkfs.noton‘/dev/sdb‘-Ito override)

Follow the prompts to add the-I parameter:

$ sudo mkfs.vfat -I /dev/sdbmkfs.vfat3.0.9 (312010)

Re-insert the USB drive, the entire disk space is back.
