Fuel Posted October 26, 2020 Share Posted October 26, 2020 (edited) Hello All, I just recently received some free SAS drives and when I got them, unRAID would not see the drives. Doing some Googling, it looked like the issue was the drives were set to 520 sector size. So, I reformatted the drive to 512 sector size, but it still doesn't see the drive? If I go to Tools -> System Devices -> SCSI Devices the drives show there, but the size isn't listed. Any help appreciated! atheon-diagnostics-20201026-1600.zip Edited October 27, 2020 by Fuel Quote Link to comment

After I restarted they finally showed up and man do I feel dumb, thanks for the help and the reply! Quote Link to comment
