I'm running an array of about 8 4TB spinner disks (mixed brands between Seagate and WD) running in a RAID 6. If I remember right (this is an old issue, only just now posting), this started ever since I had some connection issues with my server that made it inaccessible (remedied by the use of replacing my old SATA card with a reflashed SAS controller).Specifically, Drive 1 of my array regularly disables itself. I would swap the drive out with another one, and after rebuild, it would hold for a while. Eventually, the problem would come back and the drive would be disabled ("Device Disabled, Contents Emulated"). Spinning it up doesn't do anything. In the past, I would get some file corruption that would get removed after putting the array in maintenance mode and running a cleanup. However, this time I can put the array in maintenance, scan the offending disk, and it won't pickup anything. I also just tried to use a different SATA cable just in case that was the culprit. That didn't change anything though, and it also showed that it wasn't the SAS card either, as this cable connected directly to my motherboard.So different drives have no lasting effect, different SATA cables don't, different drive ports on the computer, and it always has issues with disk 1 of the array. Let me know if there's anything else to check. It has been a while of me troubleshooting this off and on, so I might have forgotten to say something.

November 25, 2025Nov 25 Community Expert There are what look like power/connection issues logged with multiple disks. Any power splitters in use?
November 25, 2025Nov 25 Author I have my drives powered by some daisy chained sata power cables. Interestingly, the drives further down the chain appear to be totally fine. But let me see how I have this configured and see if I can do away with the daisy chaining for testing.
November 25, 2025Nov 25 Author Unless you are referring to the power connection to the entire computer. In which case, its also connected to a power strip. I'll move it to another wall just in case.
November 25, 2025Nov 25 Author I didn't have a spare sata power cable extender, so for now I just had to reuse the one I had. But I did move it to another Sata power cable directly from the PSU, rather than daisy chaining them this time. Not ideal, but making due.The old drive is showing its still disabled, so I'm going to put another drive in the array and I'll rebuild the disk. I guess I'll just see if this holds out. If not, I'll try a few other combinations and see what it yields.
