ReadyNAS Pro 2 doesn't detect new disk

Hi all, My good ol' ReadyNAS Pro 2 just indicated a few days ago that disk #2 had failed (Hitachi HDS722020ALA330 1863 GB). I've replaced it (hot-swapped) with a similar one, a brand new Hitachi ...

With new disks you'd need to do a factory default, not an OS reinstall. If the disks are unformatted that should happen automatically.

Can you test the new Ultrastar in a PC (perhaps using a USB adapter)? Not sure what diagnostic software to use, but perhaps try WD's Lifeguard.

Thanks for the help, Stephen. 8-)

I've tried the factory default too, but it didn't help. Will check the disks, yes.

EDIT: looks like I can telnet into the device, but neither my last valid password nor the factory one (netgear1) are accepted.

  Thanks for the link! Will do that, although it'd be very unexpected that both brand new disks are faulty.
  
  Actually, shouldn't RAIDar detect the device even with no disk inserted?

    Yes.
    
    BTW, the hardware warranty on your pro-2 is 5 years for the original purchaser. So if you think it might be the chassis, you should check your warranty status.

  Ok, I've tested the disk with WinDFT: all good.
  
  As for the warranty, I'm of course just 6 months out of the 5 years. ;-)
  
  Time to order a new NAS...

    Does the original disk in slot-1 boot (with slot 2 empty)?
