Download page says the trial: Supports up to 3 attached devices Getting started guide says: "IMPORTANT: Your array will not start if you assign more devices than your license key allows." Perhaps getting started guide is meant more for the other licenses, but it was the one I saw last, so I thought I could have 4 drives in my trial system, as long as only 3 were assigned and that was not the case. The array would not start until I unplugged the unassigned drive. Anyways, just an FYI.

Running 6.1.3 and I had to do this as well for Format to actual do something after running "sgdisk -Z" to repurpose an older SSD as my cache drive.

I had the HDs removed from the boot order already. The first bootable device was REMOVABLE which is where the USB is listed under, everything else was disabled. I just solved the problem. I changed the SATA settings "Extended IDE Drive" from Auto to None, which existed for each drive and now BIOS makes no attempt to detect or talk to the drive. It doesn't show up in the POST screen at all, like it did before where it would then hang. But Linux still sees them. That BIOS setting was fine before Unraid formatted them, but no good after. Maybe it doesn't understand GPT.

I'm shocked as well. The HSTs were not formatted at all. The Seagate was FAT32 prior to the preclear. There is a BIOS and CMOS backup option, but it's to NVRAM. If I disable SATA, I can boot, if I plug in the original Windows drive, I can boot. With the 4TB drives I'm stuck at the "Press DEL to enter BIOS, Press ESC to enter Boot Menu" option. I was kind of surprised 4TB drives worked, maybe it's an Advanced Format issue, if Unraid aligned the drives?

I'm experimenting with the trial copy of Unraid. I'm using an old NF4 board, specifically the DFI LanParty NF4 Ultra D. It booted my 2 4TB HGST NAS drives no problem. I spent a few days in Unraid playing around. And I shut it down so I could run preclear on a Seagate 4TB I just removed from an external case. When I started the system back up, it would POST, the drives would be detected, but I couldn't enter set up or continue. I could CTRL-ALT-DEL, but otherwise it was hung. Through trial and error and combinations of cables, nothing worked so I removed the HGST drives and just started up with the Seagate attached. Ran preclear, 120 hours later, it's done, I restart, and now the Seagate has the same problem. It's pretty clear at this point, that the BIOS is trying to do something with the XFS file system and ends up hung. Have others experienced this? I tried turning off all HD settings that might circumvent the issues (booting, smart, etc) but haven't lucked into any setting that has worked. I'll try hot plugging them when Unraid is running. But not sure this motherboard supports that. Any ideas?

I installed the plugin and the original script from this thread. My parity check is currently running. Guess I have to delete the parity and data drive I have set up so far and run preclear on them once they're back to being unassigned.

Thanks guys. Using preclear is not part of the getting started guide for 6 that I'm following so how do I proceed?

Hello, I'm giving Unraid a trial. I've been lurking for a while and have read many references to the preclear script, I understand it's purpose for hot spares, but for a brand new array with brand new drives, it seems like it would also be a good idea?
