djonesax Posted April 26, 2021 Share Posted April 26, 2021 Unraid has been complaining a lot about CRC errors on my Samsung Evo 850 500GB SSD cache drive. I have checked that the cables are connected and secure, already. I have been using this drive for at least a year with no issues until recently when I was in the system replacing a drive. I have attached the SMART report and the unraid diagnostics. Any ideas? tower-smart-20210426-1017.zip tower-diagnostics-20210426-1413.zip Quote Link to comment
JorgeB Posted April 26, 2021 Share Posted April 26, 2021 Replace the SATA cable, Samsung SSDs are very picky with cable quality. Quote Link to comment
djonesax Posted April 26, 2021 Author Share Posted April 26, 2021 I replaced the cable a few hours ago and still getting the errors. Quote Link to comment
JorgeB Posted April 27, 2021 Share Posted April 27, 2021 Try a different port/controller, but SATA cable is still the most likely culprit. Quote Link to comment
djonesax Posted April 27, 2021 Author Share Posted April 27, 2021 I did put the new cable on another port after that and have not gotten any errors since. I only got one error on the new cable on the old port, before switching, where I had gotten 9,800 before Thanks for the tips. Quote Link to comment
