Ok you do much wrong. How you kill a hdd with chia mining? I dual mine burst+bhd for 4 years and 0 - Zero - no hdd died. I mine Chia for 3 months now - no hdd died  i plot 80tb with 1 nvme and it is still alive. So in my opinion you choose the wrong hardware or do something else wrong. But you cry alot in the last weeks 
By the way you can mine chia on hpool and make a new deposit address.

However he can kill - he kills. To me, Chia killed 2 HDD WD Gold Enterprise. And I only tried one for plotting and the other for storing plots. You may also have damaged discs without knowing it. Check them out with the Crystal Disk Mark
