I have a drive showing with a red X, device is disabled. About my system, I'm running Unraid 6.2 on an older Supermicro PDSMi board with a RR1U-ELi riser card with a SuperMicro AOC-SASLP-MV8 card. The drive that is having problems is connected to that card. It's a 4TB Seagate drive. I got it from a schucked enclosure a number of years back from Costco. I have two of those drives in the computer. I believe my mobo bios is up to date, I'm not sure what bios the card is running.
This first happened about 3 months ago. At the time, I stopped the array, powered down the server, pulled and reset the power and data cables, restarted the server, checked the smart report, it came back clean on the drive, so went through the process of adding the drive back into the array, Things seemed to be working well for a bit.
About a week ago, I noticed the same thing, I took the same steps only this time, I connected the drive to a different end of the breakout cable, the one I had it connected to looked a little suspect, same process, clean smart report, added drive back in.
And now, back comes the red x, same drive.
No now trying to figure out what's next. I'm not sure the drive is bad because after each reboot, it come back clean. I've tried different ends on the breakout cable (Monoprice). I could try ordering a new cable to see if that might be the issue. I'm not sure if it's the expansion card or maybe the riser or the combo. I don't think my mobo supports just the card without the riser.
Any thoughts or am I too the point where I need to look for a new expansion card, or maybe a mobo that supports more SATA connections, or supports the card I have directly instead of via riser.
