I just added a brand new 8TB drive to my server. I clicked unassigned devices so it would show up. It took a while for it to be listed. I went into unassigned devices and looked at the log and see this:

Oct 7 11:51:56 AUBURN kernel: sd 7:0:21:0: [sdn] 15628053168 512-byte logical blocks: (8.00 TB/7.28 TiB)

When it did show up this is what is showing in the unassigned device area: I can't click format.

 

I decided to go in and try to pre-clear the drive and when I select start pre-clear the process starts but just shows as starting.... I gave it about 30 minutes but still shows as starting. I stopped the pre-clear and status still showed as starting. I cleared the status so now it says Start Preclear.

 

Am I doing something wrong? Bad disk? Anything I should be checking?

I removed the disk and waited a minute then re-inserted it. This time the unassigned devices saw the disk. I just restarted the preclear again but it shows as starting... it has been this way for about 10 minutes and still there.
