I had read an Amazon review of someone with a similar problem. It’s a power down mode that the drive has and they had to put a small piece of electrical tape over one of the pins to fix it.
It took me hours to overcome the problem of the Power Disable function. This is NOT advertised as an OEM drive and so the sale is deceptive. The Power Disable Function (PWDIS) is made for off-site servers and is inappropriate for sales to general work- and home-base computer owners. It would be better to buy a retail version of the WD Purple or Red drive (7200 rpm) instead. I hope mine will continue running. (BTW, to disable the PWDIS is fairly simple, see photo). AT THE MINIMUM, THE SELLER SHOULD INCLUDE THE PROPER CABLE TO DISABLE THE PWDIS.
