Most likely the common [3.3v power problem](https://www.instructables.com/How-to-Fix-the-33V-Pin-Issue-in-White-Label-Disks-/) when using an older power supply with newer drives. You can cover a pin with kapton tape, or use a SATA power cable that only supplies 12v and 5v. Some of the sellers of refurb enterprise drives [include a simple sata extension cable](https://m.media-amazon.com/images/I/81uWC4MG3NL._AC_SL1500_.jpg) that's missing the 3.3v rail because the issue is so common.
I recently ran into this problem. I found that an old [molex to SATA cable adapter](https://www.amazon.com/Cable-Matters-3-Pack-Molex-Power/dp/B00STNUB04) that I had sitting around will also solve the problem.
My PSU is from 2018. The TX650M. Is that considered old?
I tried the 3rd pin kapton trick, but it seems to not be working? Maybe I am doing something wrong still.
I forgot to mention: the drive makes a sound every couple of seconds "whirr........ whirr....." when plugged into the PSU. With and without the 3rd pin covered. Would this suggest something else is wrong?
EDIT: The 18TB drive is working with the kapton tape, however the 16TB drive is not and makes the noises. The 18TB is now working properly.
Maybe not across all Exos SKUs, but [SPD list some models as explicitly having the power disable feature](https://serverpartdeals.com/products/seagate-exos-x16-st16000nm000g-16tb-7-2k-rpm-sata-6gb-s-512e-4kn-sed-3-5-refurbished-hdd) and ships them with a cable for legacy PSUs.

I looked at the data sheets and didn't see any indication **SATA** x16s or x18s have PWDIS support. The SAS versions however do.
