This site uses a templating system similar to Mediawiki/Wikipedia for including information about drives. There is a general template for 'drives' and a manufacturer-specific template. For example, it's useful to know if a PCB board required unlocking. This is relevant for WD and Seagate drives, but not for HGST drives. The manufacturer-specific template automatically pulls in the generic drive template.

Your drive page → calls template for manufacturer → calls template for drive

You can look at an example drive from your manufacturer of choosing. Just copy + paste the content and modify as needed. Here's an example from a wd drive:

{{template>~template|model=mymodel|pc3kfamily=somefamily|releasedate=2003|mrtfamily=someotherfamily|drivetype=hdd|recordingtype=smr}}

As you can see, each field can be edited. If you don't know a field, just leave it out.
