Linux format large hard drive

There are differences in the partitioning and file system formatting of large data disks and small disks. The market must use the  GPT  partition format,  can no longer use the small disk  MBR  partition format. mbr  partition format: The largest supported  2 TB  disk. gpt  partition format: Maximum supported  18 eb. For large disks on the  Linux  system, also use the  GPT  partition format,  can also,  the disk as a whole device without partitioning. In the  Linux  general use of  XFS  or  EXT4  to do the market file system. Partition management on a disk you can use  parted  to partition a disk on  Linux . 1,  fdisk -l  can see if the disk exists,  because the use of large disk,fdisk  can not be used as a partition tool, but should use  parted. # fdisk -lwarning: gpt  (guid partition table)  detected on  '/dev/ SDB '! THE UTIL FDISK DOESN ' T support gpt. use gnu parted.disk  /dev/sdb: 17679.7 gb, 17679696003072 bytes256 heads, 63 sectors/track , 2141037 cylindersunits = cylinders of 16128 * 512 =  8257536 bytessector size  (logical/physical):  512 bytes / 4096 bytesi/o size  (minimum/optimal):  4096 bytes / 4096 bytesdisk identifier : 0x00000000device boot      start          end      blocks   id  system/dev/sdb1                1       266306  2147483647+  ee  GPTPartition 1 does  not start on physical sector boundary.2, use  parted  to partition  /dev/sdb .
