Linux fdisk-l command

Linux fdisk-l command description of some fdisk-l values; Disk/dev/hda: 80.0 GB, 80026361856 bytes255 heads, 63 sectors/track, 9729 cylindersUnits = cylinders of 16065*512 = 8225280 bytes this hard disk is 80 GB, with 255 magnetic surfaces; 63 sectors; 9729 magnetic bars; each cylinder (magnetic column) the capacity is 8225280 bytes = 8225.280 K (about) = 8.225280 M (about ); partition sequence boot starts to terminate capacity partition type ID partition type/dev/hda1 * 1 765 6144831 7 HPFS/NTFS/dev/hda2 766 2805 16386300 c W95 FAT32 (LBA) /dev/hda3 2806 9729 55617030 5 Extended Description: Hard Disk Partition representation: hd * x or sd * x is used in Linux, * Indicates a, B, and c ...... the numbers 1, 2, and 3 represented by x ...... hd is mostly an IDE hard disk; sd is mostly a SCSI or mobile storage; Boot: indicates a Boot partition. In the preceding example, hda1 is a Boot partition; active partition activeStart (start ): indicates that a partition starts from X cylinder (magnetic column); End: indicates that a partition ends with Y cylinder (magnetic column); id and System indicate a meaning, confirm the partition type by specifying the id. For example, if 7 indicates NTFS partition, Blocks (capacity) means capacity, and its unit is K; the value of a partition capacity comes from the following formula; Blocks = (End value of the corresponding partition-Start value of the corresponding partition) x unit cylinder (magnetic column) so let's calculate the size of the hda1 Blocks: hda1 Blocks = (765-1) x8225.280 = 6284113.92 K = 6284.113.92M
