Display device serial numbers (#751251)
Run "hdparm -I /dev/DISK" to get the hard drive serial number of every device which has one and display it in the Device Information. The displayed value can either be the actual serial number, "none" or blank. "none" means the device doesn't have a hard drive serial number, such as for Linux software RAID arrays, BIOS fake RAID arrays or USB flash drives. Blank means something went wrong getting the serial number. Either it couldn't be found in the hdparm output or the hdparm command wasn't installed. Example real hard drive: # hdparm -I /dev/sda ... ATA device, with non-removable media Model Number: SAMSUNG HM500JI Serial Number: S1WFJDSZ123732 ... Example Linux software RAID array: # hdparm -I /dev/md127 /dev/md127: HDIO_DRIVE_CMD(identify) failed: Inappropriate ioctl for device On my desktop with 4 internal hard drives 2 Linux software RAID arrays on those hard drives, 2 USB flash drives and 1 USB hard drive attached, running hdparm 9 times added 0.07 seconds to the device refresh time. Bug 751251 - Show serial number in device information

hdparm - used to query disk device serial numbers

vol_id - used to read volume labels
