Can't get OMV6 to see new drives

Newbie in need of some direction. Got sick of trying to use MyCloud storage. So got a Mini PC and put OMV6 on it. It has internal 500GB and I added a new 2 TB drive inside. Everything looks good to this point. Pulled the drives from my MyCloud Home Duo devices. I have two 2TB and two 4TB WD Red drives that I put into a Terramaster D4-300 enclosure. I grabbed AOMEI and wiped / killed partitions in the drives. I partitioned and formatted one drive just to prove I could see it on my windows PC system, and I can. I attach the usb connection of the Terramaster to the Mini PC and I cannot see any evidence of the drives in the OMV NAS. What am I missing? TIA Don

Update - I was able to see all four drives in the TerraMaster D4-300 box when it was attached to my laptop. I found that if I pull three of the four drives out of the box, I could see the remaining drive in OMV. I could see any drive in OMV as long as it was the only one in the box. Works for laptop but not for Mini PC OMV? Anyone have an idea for a fix?

That sounds right to me. Yes, laptop is Windows. I really want to use this with the OMV (Debian Linux) NAS. Convenient arrangement if I can get it to work. Thanks.

Well, looks like a dead-end. TerraMaster is writing it off as an OMV problem. See below.

Hello,

Thanks for contacting TerraMaster!

Sorry that is almost impossible for us to troubleshoot the problem at OMV for you.

If it works at your laptop, it should be normal for use.

Best regards

Well, I've sent it back out of frustration. I may just use individual USB SATA enclosures to add my drives. Thanks for the responses to my issue.

Well, it's kinda the result of running down the rabbit hole! I didn't have an old PC with sata ports lying around. I thought I'd try the Mini PC and OMV route along with reusing the drives from a MyCloud device I was totally sick of. I thought (thinking is questionable here) I could just attach the drives with USB enclosures. But then I found the TerraMaster device and the form-factor was really nice. Just wouldn't work properly with OMV usb. So now I ditch the TerraMaster and go back to the original plan. Kinda hard to back up from here, so we'll just forge ahead. Thanks for the comments.
