disk/dev/sda:10.7 GB, 10737418240 bytes

255 heads, Sectors/track, 1305 cylinders

Units = Cylinders of 16065 * 8225280 bytes

Sector size (logical/physical): bytes/512 bytes

I/O size (minimum/optimal): bytes/512 bytes

Disk identifier:0x000a87b0

Device Boot Start End Blocks Id System

/DEV/SDA1 * 1 512000 Linux

Partition 1 does not end on cylinder boundary.

/dev/sda2 141 614400 Swap/solaris

Partition 2 does not end on cylinder boundary.

Fdisk-s partition ... < partition number > outputs the specified partition size to the standard output, in chunks.

Fdisk-h

I. Zoning essentials

(1) Any number of primary partitions, but required (1<= primary partition <= is less than or equal to 4. For example, 4 primary partitions, 3 primary partitions, 2 primary partitions, or one primary partition)

(2) Extended partition and primary partition, 3 primary partition + one extended partition 1<= primary partition <= less than equals 4 for example: 3 primary partition + one extended partition or two primary partition + one extended partition 1 primary + one extended partition

(3) If the disk is divided into 4 disk partitions, it will generally be used: P+p+p+p p+p+p+e
