Toshiba HDD Date Calculator


I'm currently trying to research a way of calculating the date code from the serial number on the Hard Drive?

Does anybody have any information on this? Happy

I use the old fashioned method.

I read the label on the drive. No software or PC required.

Label reading

Yes, sorry maybe I wasn't clear.

Some Toshiba drives do not include the Date of manufacture on the label.
I require a way of calculating this without software or PC

Only been reading this for decades.

Pre-DOS and even last year still finding dates on drives. Even if the dates were not on the printed label (worn off) you can get dates off the chips on the PCB to get an approximate date.

Then we have some drives that were only made for a few months. For that I take the drive model # and google that.

And finally some makers have a warranty claim web page that you pop in the serial number. Not as sure as the above but may help cover the last few other cases.

further info required

Thank you for your advise.

Should the situation arise were the DOM is not printed a Toshiba
hard drive or has rubbed off

I am working in a unique situation were I require to be able to calculate the DOM from the serial number alone without the use of software or the internet.

Then you MUST ask the HDD maker for that data.

Here I find the latest date on the chips to be so close to the DOM it's not funny. I've been within a few months over and over using that method. As most of the drives are so far OOW (out of warranty) the date is only for logging in the company failure report.

That said you might encounter an OCD person that wants it spot on.

Here's the formula

First Three Letters of Serial # Month, Year, Day

Month of production (1,2, ... October is X, November Y, December Z)
Last digit of the year of production (eg. 0 for 2010, 4 for 2014, 5 for 2015)
Day of production (1,2,...9,A,B,...) (eg. G is for 16)
