Identifying a Hard Disk Using hdparm command.

When working with hard disks it is sometimes difficult to determine which piece of hardware corresponds to which Linux device. The hdparm command can provide identifying information to tie the physical drive to the device file in /dev. For example to find the Model and Serial Number of all /dev/sdX devices present on the system

Code: [Select]

# hdparm -I /dev/sd?|grep -E "Number|/dev"
Example Output:

/dev/sda:
        Model Number:       HDS722516VLSA80                         
        Serial Number:        VN6D3ECDD7RG1D
/dev/sdb:
        Model Number:       WDC WD740GD-00FLA1                     
        Serial Number:        WD-WMAKE1690676
/dev/sdc:
        Model Number:       HDS722525VLSA80                         
        Serial Number:        VN6J3ECFEALJRD
/dev/sdd:
