Seagate Date Code on HDDs – Why Code the Date ?
The firmware problems have me doubting Seagate’s competency. The date code on HDDs has me doubting Seagate’s sanity.
Googling “Seagate Date Code” will turn up sites that have decoders and explanations of the date coding. Apparently the coding is as follows :
Date Code = YYWD or YYWWD
YY = fiscal year, beginning on the 1st Saturday of July YY-1
W[1-9] or WW[10-52] = fiscal weeks from 1st Saturday of July YY-1
D = days from the beginning of week WW (weeks run from Saturday to Friday
This has me wondering why code the date at all? Why not simply put the date on the HDD?
The “fiscal” in the coding suggests a link with accounting and inventory management but how could a date code be more useful than a simple date?

Probably helps them keep track of manufacturing sets/runs, when they implement different batches with slight changes to something.
There's a small program that can automatically decode the code if you want, google "SeagateDateCode.zip".
