levijay Posted October 7, 2022 Share Posted October 7, 2022 (edited) Hey there, I am at wits' end with this issue. I have tried 3 different HBA cards (with the original working fine for over 5 years). I have 8x 8TB drives and a 12TB parity drive which was working fine until about 1 month ago, the drives would suddenly drop off and I would have to restart unraid for them to appear again. Nothing has changed on the hardware side (except to try different HBA cards). I have put the HBA cards in different slots to no avail - same issue. I have attached the log from today. I have connected the 12TB parity to an onboard SATA - this appears to have no issues. CPU: AMD Ryzen 7 3700X 8-Core @ 3600 MHz Mobo: B450M MORTAR MAX (MS-7B89) Version: 6.11.1 Any help would be appreciated. Thank you, Levi syslog.txt tower-diagnostics-20221008-0902.zip Edited October 7, 2022 by levijay Quote Link to comment
