Finding the serial number of a hard drive on a Linux console (as root) is simple with the right tool.
The right tool in this case is hdparm (using the -i option).
-i will query the device directly for the details.
Example:
themachine:/proc# hdparm -i /dev/sda /dev/sda: Model=ST31500341AS , FwRev=CC1H , SerialNo= 9VS21ZXM Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs RotSpdTol>.5% } RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=4 BuffType=unknown, BuffSize=0kB, MaxMultSect=16, MultSect=?16? CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=18446744072344861488 IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120} PIO modes: pio0 pio1 pio2 pio3 pio4 DMA modes: mdma0 mdma1 mdma2 UDMA modes: udma0 udma1 udma2 udma3 udma4 udma5 *udma6 AdvancedPM=no WriteCache=enabled Drive conforms to: unknown: ATA/ATAPI-4,5,6,7 * signifies the current active mode |
Using the option -I instead gives even more information:
