cyl cylinders 柱面
hd heads 硬盘面
sec sector 扇区

计算公式
磁面个数 x 扇区个数 x 每个扇区的大小512 x 柱面个数 = 硬盘体积 (单位bytes)

本例中
10号磁盘：
hd * sec * 512 * cyl = 64*256*512*638 = 5G

--linux

[root@test ~]# fdisk -l

Disk /dev/sda: 292.5 GB, 292527538176 bytes
255 heads, 63 sectors/track, 35564 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
