September 23, 20241 yr One of my disks keeps going offline. And a few weeks back a disk would go randomly offline. I have three HDDs, one parity and two data, and one SSD, cache I had the system running for a couple of years and only recently did start going haywire. I replaced all the SATA cables. How can I find exactly what is wrong with it? Is it the cables, the hard drives, or the mobo/CPU? Any advice would be appreciated. tower-diagnostics-20240923-0018.zip
September 23, 20241 yr Community Expert Looks more like a power/connection issue, but since the disk dropped there's no SMART, post new diags after a reboot and array start.
September 23, 20241 yr Author Restarting fixes the issue, usually. Here is the diagnostics after a restart. tower-diagnostics-20240923-1908.zip
