Hi,

sda is an internal SATA drive

Model Family:     SAMSUNG SpinPoint T166
Device Model:     SAMSUNG HD321KJ
Firmware Version: CP100-12

sdb is an internal SATA drive

Model Family:     SAMSUNG SpinPoint F3
Device Model:     SAMSUNG HD502HJ
Firmware Version: 1AJ10001

sdc is an external "USB" drive

Model Family:     Western Digital Green
Device Model:     WDC WD20EZRX-00DC0B0
Firmware Version: 80.00A80

Load cycle count isn't shown for sda, it does not increase for sdb but
it increases for sdc.
