bro, can u snapshoot the photo? i dun think it is wd black but a black and white label sticker, as this yr i have warranty green, blue , black wd, total around 11 unit, for blue wd rma, i always got the new wd blue unit for replacement, same goes to the black wd, but for the green wd, i always get back either a new green wd or a refurbished recertified black sticker wd hdd.
I didn't come to a conclusion that it is WD Black model because of the sticker (there's no green/blue/black wording), but because of the MDL (google this WD5001AALS). It is also heavier than the green.
I also ran a HDTune benchmark:

Compare that to other WD5001AALS benchmark that I found on the net:

Plus the drive gets hot fast, another 'trademark' of the Black series.. lol.
I am just luckier than you perhaps? Not the first time something like this has happened.. last time I RMAed a 1TB MyBook Essential and got a 2TB version in return. Others have reported something similar as well.
BTW, this seems to be a shortstroked drive. Read this:
