i have received the following string of errors during a preclear cycle of a new disk (disk is attached to a AOC-SASLP-MV8 card, not the onboard sata of the a880g+ board. running unraid 4.7 and latest preclear script:

i have read others reporting the same issue but i have yet to see someone provide a valid explanation or solution.

seems to be an issue when preclearing with the supermicro AOC-SASLP-MV8 card.

guess i can try to preclear future drives with the onboard sata ports.

 

can anyone provide a definitive answer/solution/explanation?

thanks!

anyone?
