hard disk partitions, we know that the total number of primary partitions (including extended partitions) cannot exceed four, nor can we enclose extended Partitions between primary partitions. According to this principle, it is easier to divide hard disk partitions and reduce unnecessary troubles in the future;
1. Use fdisk-L to view the number of hard disks mounted to the machine and the partition information;
[Root @ localhost beinan] # fdisk-l
Disk/dev/hda: 80.0 GB, 80026361856 bytes

must know how to view the partition information of a hard disk and format it accordingly. For example, you can use fdisk-L to view the partition information;
Refer to: Linux disk partition, file system, usage commands and related tools
For example, if I want to format a partition in a mobile USB flash drive, the panorama should be:[Root @ localhost beinan] # fdisk-lDisk/dev/hda: 80.0 GB, 80026361856 bytes255 heads, 63 sectors/track, 9729 CylindersUnits = cylinders of 16065*512 = 8225280 bytesDe
