ReadyNAS 214 fails to recognise 4th drive

Please help! Have been trying for weeks to get my ReadyNAS 214 to recognise the 4th drive I inserted. For some reason, RAIDar could briefly see the 4th drive but the admin page will not. Feels li...

Hi NAS-Bodger,

Welcome to the forums.

I would like to verify a few things regarding the ReadyNAS setup.

1. What firmware are you using?

2. What RAID level are you using?

3. Are you replacing a hard drive or are you expanding it?

4. When you see it on RAIDar, what does it say? (screenshots from the RAIDar and admin page might be best).

You could probably do a test on the new HDD using its own utility on your PC, just to make sure the HDD is healthy.

Thank for getting back to me FramerV,

The firmware I'm running is 6.6.1 and I'm using RAID 5 (X-RAID). I'm trying to expand - I have 3 drives in already and want to add a 4th. Screenshots attached.

Thanks,

  Is the new drive at least as large as the other three?

    It's identical - they're all 2TB WD Red

  Hello NAS-Bodger,,
  
  No, do not remove the already existing one that is part of the RAID.
  
  Maybe you could test the 4th disk with disk tools.

    Hi JennC,
    
    Yep, tried that. Did a comprehensive scan using Tech Tools and found no problems. I then wiped it and put it in the NAS - no joy. Then took it out and gave it a FAT-32 format using a a USB HDD enclosure and Disk Utility in OSX 10.12. I thought it might recognise it if it had some kind of format but that didn't work either :(

Hello NAS-Bodger,,

Could you check please on the admin page's System > Volumes? This should show the 4th disk with red mark while the other 3 in green.

  Hi JennC,
  
  All I see is three drives (see attachment). It it safe for me to remove the 3rd drive and put it in the 4th slot to see if it's the slot that's the problem?
