[font=Arial]Disk /dev/sdb: 8019 MB, 8019509248 bytes
247 heads, 62 sectors/track, 1022 cylinders, total 15663104 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0xe2441ca9

Device Boot Start End Blocks Id System
/dev/sdb1 * 2048 32767 15360 b W95 FAT32
/dev/sdb2 32768 15663103 7815168 83 Linux


正常从63 开始分一区(原来是这样), 现在变成从2048开始了!

    fdisk -u -l
    查看分区

    fdisk -l和fdisk -lu不同

    root@debian:~# fdisk -u -l /dev/sda

    Disk /dev/sda: 1981 MB, 1981808640 bytes
    255 heads, 63 sectors/track, 240 cylinders, total 3870720 sectors
    Units = sectors of 1 * 512 = 512 bytes
    Disk identifier: 0x000c308b

    Device Boot Start End Blocks Id System
    /dev/sda1 63 3212999 1606468+ b W95 FAT32
    /dev/sda2 3213000 3855599 321300 83 Linux
    root@debian:~# fdisk -l /dev/sda

    Disk /dev/sda: 1981 MB, 1981808640 bytes
    255 heads, 63 sectors/track, 240 cylinders
    Units = cylinders of 16065 * 512 = 8225280 bytes
    Disk identifier: 0x000c308b

    Device Boot Start End Blocks Id System
    /dev/sda1 1 200 1606468+ b W95 FAT32
    /dev/sda2 201 240 321300 83 Linux

    这是分区的最小单位,和硬盘不同啊
    Units = cylinders of 15120 * 512 = 7741440 bytes

    U盘默认不用分区,整个就是一个区(不是分一个区/dev/sdb1,而是只有一个/dev/sdb)
    用U盘格式化工具,格式化成HDD(windows下有很多相应工具),就可以像硬盘一样分区了。
