Hi all,
I have a seagate backup plus 5TB.
When I plug-in the hdd, I see the serial number (as printed in the
back of the HDD) in dmesg.
usb 2-1.1: SerialNumber: XXXXXXXX
[ 5.244161] usbcore: registered new interface driver usb-storage
[ 5.245790] scsi host6: uas
[ 5.246015] usbcore: registered new interface driver uas
[ 5.247071] scsi 6:0:0:0: Direct-Access Seagate BUP BK
0108 PQ: 0 ANSI: 6
[ 5.285452] sd 6:0:0:0: [sda] 9767541167 512-byte logical blocks:
(5.00 TB/4.55 TiB)
[ 5.285458] sd 6:0:0:0: [sda] 4096-byte physical blocks
[ 5.285786] sd 6:0:0:0: [sda] Write Protect is off
[ 5.285790] sd 6:0:0:0: [sda] Mode Sense: 53 00 00 08
This serial number is correct ! (Actuial serial number is obfuscated)
Whereas, when I do a hdparm or smartctl -i , I get a different serial number.
ATA device, with non-removable media
Model Number: ST5000LM000-2AN170
Serial Number: YYYYYYY
Firmware Revision: 0001
Transport: Serial, ATA8-AST, SATA 1.0a, SATA II
Extensions, SATA Rev 2.5,
(actual serial number obfuscated)
Can someone explain why please ?
When I use seagate seatools, it reports both the USB-STORAGE and also
the internal HDD with the same XXXXXXXX serial number (on windows).
Regards

Your USB hard drive consists of a USB to SATA bridge and a SATA HDD. My guess is that the kernel reports (via dmesg/journalctl) the USB iSerial of the bridge as "SerialNumber" and hdparm reports the SATA serial number of the HDD.
