Iv been running unraid for about 3 to 4 years now and have never had a udma crc error before. But about 15 days ago I got a LSI 9300-16I and since then iv gotten 3 different udma errors. One happened the day of install and seemed to resolve itself. However sometime last night my main data drive spun down and would not spin back up without a reboot. So I rebooted and got a udma error on that drive. If it were just that drive I might think the hba was bad or something but I also got a error on an ssd that is just plugged into a sata port on the mobo. Im at somewhat of a loss. I could just get new cables and a new hba but id like to avoid that if something else is going on. Id attached the diagnosis if that will help.

This is typically the miniSAS cable, though that amount of errors is not a reason for concern, but if it keeps happening, you may want to replace it.
