I have been trying to stress test a new 8TB drive using the Binhex Preclear Docker to replace my parity drive. I have tried 3 times and the test has failed to complete every time. I have nor received any emails from the docker, and when I look at the NoVnc window it is blank except for the prompt. When I first started trying to preclear the 8tb drive all of my disks were OK, but now I have three 4 drives with smart errors, including the 8Tb drive. Diagnostics attached.

Looks more like a connection problem, replace cables on that disk and try again.

If you mean the UDMA_CRC errors those are a connection problem, usually the SATA cable.

I notice that parity has quite a few re-allocated sectors.   While not a concern as long as that number remains stable it is certainly one to keep an eye on as if it keeps increasing the disk is probably on its way out.
