I noticed today that the serial number for Toshiba drives, as retrieved by smartctl(8) is not the whole serial number. I am not sure why.

I discovered this when I went to check the warranty information for a drive. The drive is fine; I just wanted to check. Using smartctl, I got this:

$ sudo smartctl -a /dev/ada5 | head
smartctl 6.0 2012-10-10 r3643 [FreeBSD 9.1-STABLE amd64] (local build)

=== START OF INFORMATION SECTION ===
Device Model:     TOSHIBA DT01ACA300
Serial Number:    Z2U4W1XGS
LU WWN Device Id: 5 000039 ff4c23712
Firmware Version: MX6OABB0
User Capacity:    3,000,592,982,016 bytes [3.00 TB]
Sector Sizes:     512 bytes logical, 4096 bytes physical

Right there, on line 7, you can see the serial number. Count it. It’s 9 characters.

Now visit the Toshiba Warranty page (I listed a few such warranty links in a recent post). You’ll get told: Warranty could not be determined for this serial number.

Now click on How to find the T-S/N. The serial number on that graphic has an extra three characters. There is even a mention of Input the drives 12 digit Toshiba S/N, NO SPACES.

I just think it would be more convenient to find out the number from smartctl(8) without having to pull the drive.

Let’s see what Toshiba Support on Twitter says.
