Welcome everyone in the new year.

I would like to ask you  dear readers, senior specialists in the field of hard drives and those who have knowledge of hard disk firmware about two issues that can be very useful for me as well as for many users of Hitachi / HitachiGST / HGST hard drives and hdds of  other brands.
I have two questions:
1 / Did the Hitachi / HitachiGST / GST company from 2010-2017 put somewhere on the web the pattern of its company sticker/label on hard drives with a detailed explanation of the individual units on this sticker?
If so, at what address?
Is there any knowledge available on the subject?
On the the manufacturer site?
From other websites, which in various aspects deal with the subject of IT or hard drives?
What is a real, authentic company hard disk sticker/label from that period  (link)?
Was there any company disk sticker/label pattern established in 2010-2017 by the Hitachi/HitachiGST/HGST company?
What was he like?
Were there many patterns?
What did they depend on?

Comment: As of today (01/2020) - this company is gone, the website does not exist, all attempts redirect to the WD website with its current offer. Some data from 2010-1017 can be viewed on the Internet Archive / Wayback Machine, but so far I have not been able to view the standard factory hard disk sticker along with its description find. In addition, some components of these former sites automatically redirect to the current WD page, which makes searching difficult, as WD does not provide this data.
I would like to see if Hitachi / HitachiGST / HGST had one corporate sticker/label pattern at that time, or many patterns depending on the disk model or factory producing the disk series.
Then, of course, there can be several or even several dozen patterns and the matter gets complicated.
This is generally the subject of the so-called company / factory product identification.

2 / Is the detailed technical and identification data contained in the hard disk software placed by the manufacturer are they modifiable? I mean, can they be changed / modified after some time of using the disk?
For example - general disk life hours or technical specifications. But also identification data such as serial number, model number etc. And even the disk manufacturer.
These data stored in the disk software are modifiable or unmodifiable in any way?

 
Comment: This question concerns the countless cases of purchasing a hard disk as a new one, which it turned out to be used. Or a used disk whose condition was worse than declared by the seller. And when the identification data from the disk sticker did not coincide with the data shown by disk tools.

All information is greatly appreciated. Thank you for them on behalf of myself and (I hope) many, many users not only Hitachi / HitachiGST / HGST drives but any hard drives.
