It's A Digital Disease!

Hi, noob datahoarder here looking for some help (less than a month into building my first TrueNAS server)

Hardware:

Motherboard: SABERTOOTH Z97 MARK 2/USB 3.1

PSU: Corsair CX600 (600W)

CPU: i5-4670

RAM: 32GB

Drive: 20TB EXOS X20 ST20000NM007D (SATA Port)

Other drive in pool: 20TB SkyHawk ST20000VE002 (SATA Port)

Software/Firmware:

BOIS: Version 3503 (latest)

Drive Firmware: SN06 (latest)

OS: TrueNAS Scale ElectricEel-24.10.0.2

Let me give you the timeline:

1. I bought a used 20TB EXOS drive (still under manufacturer’s warranty)
2. When I hooked it up, I was getting an I/O error when trying to quick wipe it. I would also get a Read SMART Data failed: Connection timed out when attempting a SMART test
3. I thought the drive was dead (used drive) and since it was still under warranty I sent it in for an RMA
4. Seagate sent me a new EXOS drive
5. Hooked the new one and tried to wipe it and SMART test it- same errors
6. After a couple of afternoons of googling I saw some people recommended disabling EPC and power balance features, so I did it with OpenSeaChest commands (and verified these features remained disabled after a power cycle)
7. I was then able to wipe the EXOS drive and run a long SMART test with no errors
8. I then created a 20TB Mirror Pool with this drive (everything seemed to be going fine)
9. I’ve been able to copy files to the pool (8TB worth of data. And by the way, I have another 20TB WD external drive on a different server as backup)
10. The issue is that sometimes while copying data to or from the pool (seemingly random), the drive gets removed from the pool (degrading it)
11. After this happens, if I try to do a short SMART test (or wipe) I get the same errors I was getting initially
12. Checking the drive with SeaChest shows the EPC feature as enabled but won’t let me disable it (when attempted it reports EPC Feature set might not be supported. Or EPC Feature might already be in the desired state.)
13. Trying to disable Power Balance throws a Failed to set the Seagate Power Balance feature!
14. A power cycle makes the EPC feature show up as disabled again, and makes the pool go back to ONLINE with the EXOS drive back into it
15. I can copy data to and from the pool again but after a while its back to number 10

Has anyone experience something similar? Any help would be well received as I’m a total noob with TrueNAS.

Forgot to mentioned I’ve tried swapping power and SATA cables/port with the same results. At some point I also tried upgrading the firmware on the drive to the latest available.
