bloodlust Posted January 3, 2021 Share Posted January 3, 2021 (edited) Over the last 3 months, I have swapped out my disk 2 HDD a total of (3) times. The first drive was older and I believe was beginning to fail. It was throwing errors and unraid was disabling the HDD. I purchased a brand new drive, It lasted about 2 months and began the same deal. I sent it off for warranty replacement. I then purchased yet ANOTHER new drive. It's been in the array for about 3 weeks and now it's throwing errors. WTF is going on? Is it possible to find out what might be causing the drive to throw errors? This third drive has not been disabled yet by unraid but it showing array errors. I would imagine it's only a matter of time. Also, Everytime a rebuild of the drive seemed to be successful when it was replaced the last two times. I also run a parity check usually every few months on my system. unraid-diagnostics-20210103-1521.zip Edited January 3, 2021 by bloodlust Quote Link to comment
trurl Posted January 3, 2021 Share Posted January 3, 2021 Connection problems are much more common than actual disk problems and it looks like connection problems. Probably nothing wrong with those other disks you used before. Check all connections, both ends, power and SATA, including splitters. Quote Link to comment
bloodlust Posted January 3, 2021 Author Share Posted January 3, 2021 I did replace the SATA cable when I replaced the drive the third time. I also switched SATA ports wondering if that might not be a possible problem as well. The only thing not changed was the power cable as I only have 1 modular cable, I guess I could put it on one of the other connectors to a different drive. Is there anyway to see if this is the actual issue or is it more or less swap a cable and see what happens type of troubleshooting? Also, I do have a Marvel SATA card controller in the system, Which I know some people have had issues with. I've had mine in my system for almost 6 years and have never had an issue with it on any of the 6 drives currently connected to it. When I switched SATA ports, I took that drive off the MB SATA port and plugged it into the SATA card. Quote Link to comment
trurl Posted January 4, 2021 Share Posted January 4, 2021 Be careful with modular power supply cables. You must only use the cables that came with the supply since the pinout is not standardized. Are any disks still using Marvell? Some people are able to use those as long as they don't try to use IOMMU (hardware passthru to VMs). Quote Link to comment
bloodlust Posted January 7, 2021 Author Share Posted January 7, 2021 Yes, I have 6 HDD's on the Marvel card. Never had any issues with it. The drive that's giving me problems was plugged into the MB, Not sure what chipset is uses however. I switched it over to the SATA controller card and haven't seemed to have any issues the last few days. Quote Link to comment
