I just bought two Western Digital Easystore 12Tb HDD. I haven't taken them out of the external enclosure yet because I am out of SATA ports on my motherboard. I have them plugged into the back of my motherboard as regular USB 3.0 devices. Previously, I have successfully precleared drives with them directly plugged into the SATA port and a USB 3.0 port so I know this is something that can be done. I currently have one drive part of the array as a USB device and everything has been working fine.
I am still on the trial version of unRAID 6.8.3. I'm running Preclear Disk version 2021.01.03, Unassigned Devices version 2021.01.16b, Unassigned Devices Plus version 2021.01.24.
I load up the Preclear plugin and on the rightmost column Preclear status for both drives shows up as "Disk mounted" so I click "Start Multiple Sessions."
The first issue is that the box that says "Select Disks: Preclears Disks" is a gray font and if I click on the box for the drop down menu, then the 2 drives are also gray. I tried this with only one disk plugged in and it's the same gray font but now with only one drive showing. I can't recall exactly but I think on my previous runs, they were a black font.
I then click "START" button which turn it into 3 white dots that light up gradually like a loading logo. That button stays like that for about 30mins without anything happening or showing me the progress. I have tried this with both gfjardim - 1.0.20 script and Joe L. - 1.20 script with the same results.
