i looked at the sata card specs and there is nothing about marvell controller. When I order another card, any suggestions on how I can tell if its as marvell controller or not?

so there is 1 disc using the pcie sata card, i believe that is ata4.01. Is the pcie sata card the card you are referring to as the marvell controller?

ran memtest, 7 passes, no errors.

I am still getting errors, ata7 is my parity drive. I have attached latest log, any ideas? I ran parity with correction, then without. Got 0 errors first few times, then 1 error, then 4 errors. Any suggestions would be greatly appreciated. tower-syslog-20200929-1448.zip

Thank you so much. At least now I understand what is happening. I believe that unclean shutdown was exactly what caused the errors to occur. I did not have a battery backup on the unraid server but now I will, my bad. QUESTION - so if there were errors in the parity drive, why does it still say PARITY IS VALID? Wouldn't the errors prevent some data from being properly recovered? That message kind of gives false security.

i attached the zip file, thx tower-diagnostics-20200807-0057.zip

Hello, running 6.8.3, 1 parity, 4 data drives. Normally, parity check has 0 errors. Last few runs I am getting 135+ errors. Reading other posts, is it true there is no way to see what those errors are, that would not make sense? I looked in the log but was unable to find. There must be some way to read what the errors are so you can address them? Also, is the only way to run mem tests from bios?
