Identify the Partition in Linux, find the position where it is located in your hard drive. How much is free and available size.

watchout for these strings in your commands you will observe now onwards

There is a special nomenclature that linux uses to refer to hard drive partitions that must be understood.

/dev/hda /dev/hdb and /dev/sda /dev/sdb and etc.,

Use the following command

`ls -l` while in the /dev dirtectory::

brw-rw----    1 root     disk       3,   0 May  5  1998 hda
brw-rw----    1 root     disk       8,   0 May  5  1998 sda
crw-------    1 root     tty        4,  64 May  5  1998 ttyS0

A device file is a file with type c or b

"character" devices, devices that do not use the buffer cache
"block" devices, which go through the buffer cache

In the listing above, this is indicated by the first character of each line.
In Linux, all disks are represented as block devices only.

By convention, IDE drives will be given device names
from /dev/hda to /dev/hdd.
Hard Drive A(/dev/hda) is the first drive
& Hard Drive C (/dev/hdc) is the third and followes.

drive name	drive controller	drive number
/dev/hda	1	1
/dev/hdb	1	2
/dev/hdc	2	1
/dev/hdd	2	2

A typical PC has two IDE controllers, each of which can have two drives connected to it. For example, /dev/hda is the first drive (master) on the first IDE controller and /dev/hdd is the second (slave) drive on the second controller (the fourth IDE drive in the computer).

SCSI Drives or Pen Drives check out when you are not having scsi controller in your Laptop or System.

drive name	drive controller	drive number	partition type	partition number
/dev/sda1	1	6	primary	1
/dev/sda2	1	6	primary	2
/dev/sda3	1	6	primary	3

Logical Partitions these are the drives same as Windows D drive, E drive and etc.,

i.e Primary Master connected Hard Disk with

drive name	drive controller	drive number	partition type	partition number
/dev/hdb1	1	2	primary	1
/dev/hdb2	1	2	extended	NA
/dev/hdb5	1	2	logical	2
/dev/hdb6	1	2	logical	3
