Fdisk –l 详解:
[root@jetsenLin ~]# fdisk -l
Disk /dev/sda: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders
Units = cylinders of 16065 * 512 = 8225280bytes
注释:这个硬盘的大小是10.7GB,有255个磁面,63个扇区,1305磁柱(cylinders)
每个cylinder(磁柱)的容量是 8225280 bytes=8225.280 K(约为)=8.225280M(约为);
Device Boot Start End Blocks Id System
/dev/sda1 * 1 13 104391 83 Linux
/dev/sda2 14 1305 10377990 8e Linux LVM
磁盘容量的算法是
磁面数*扇区数*磁柱面数*每个扇区字节数=XXX(单位bytes)
