WD EasyStore 10tb shows up as 8tb?

So I shucked a couple of WD EasyStore drives to use for my server - one 8TB from 2017 and one 10TB from 2019.  Here's what I did:

 

  1. I first plugged in the 8TB and it was recognized with no issue.
  2. I then proceeded to put in the 10TB but that was not recognized.
  3. I have an ASRock E3C224 which has 6 SATA3 slots - 4 by Intel and 2 by Marvell. The 8TB went on the last remaining Intel slot and the 10TB went on a Marvell slot.
  4. Thought maybe the Marvell slot is not configured or not working or something ... so I swapped the SATA cable from the 8TB to the 10TB.  
  5. UNRAID recognizes that a drive is there, but says it's 8TB.

 

So the questions that pop up are

  1. Is there some sort of limiter that's only allowing 8TB?
  2. Is UNRAID caching the presence of the 8TB I first put in? The drive ID value is the same no matter which drive I put in.

 

Anyone with experience or thoughts?

 

Thanks!

For Unraid to recognize a new drive, the array must be stopped and the GUI needs to be refreshed after the drive is added (hot swappable).

Or power down the system, add the new drive and power up the system. It should show the new drive. There are no limitations for 10 TB drives (or larger).

The symptoms I posted were done using the power down approach.

I don't see any 10TB disk connected there's one 8TB but it's connect to a USB port:

Ah shucks you're right.  I didn't realize that the USB attached drive (which happens to be the same kind of drive as the one I shucked and am trying to install) shows up as an option for the array disks.  

 

Looks like I'll have to try out that kaplon tape.   Thanks @johnnie.black
