April 29, 20242 yr I have an Unraid setup that's been flawless for the past few months. I have 9 20TB Exos drives connected to an 8 port LSI 9207-8i HBA + one additional SATA cable to the motherboard. In the past day, two of my drives threw a "Device Disabled, Contents Emulated" failure at me. Two more come up as healthy but I see a lot of read errors for them during a parity sync. All four drives all belong to the one of the 4 port HBA cables + single 4 port SATA power connector. Retrying any parity sync eventually brings the drives back to disabled. Considering the rest of my drives are fine, I assumed the HBA cable was at fault. I swapped the HBA cables but still got the errors on the same drives. I've ordered a replacement cable just in case but now I feel doubtful that's the issue. I'd appreciate any other insights or opinions on potential root causes. Edit: Swapped PSU cables and the other set of drives started failing. So I guess it really is my power supply. I'm really surprised that the cables themselves could be responsible. unraid-diagnostics-20240428-2319.zip Edited April 29, 20242 yr by stringybird
