Didn't Toshiba acquire Hitachi's 3.5" business? :P
Sure, they are manufactured in plants previously owned by Hitachi, but the design is Toshiba's, I believe.

They acquired part of the business, not 100%, that's why the factory is still Hitachi.
Now, maybe the design is Toshiba, don't know.

please SCREENSHOT

Agreed !
Really hard to figure out what is going on without any screenshot.
Even if you've already explained what you did, some screenshots will be really helpful.
From CrystalDisk, from Disk Management, from anything.
Please !
