This had me scratching my head today. Plugged in a brand new 4Tb Toshiba Canvio HDD that I bought on Amazon as a destination for a case. I happened to open up WD Discovery software, to reset encryption on another drive that I had sold on eBay & previous owner hadn't sanitized.
Was quite surprised to find this:

Definitely looks like a Toshiba inside. So I guess WD's tool just mistakenly thinks these drives are My Passport Slim drives.
