Raid configuration is set to 2 disks, but I'm only using 1 disk

I have used my ReadyNAS Ultra 2 for a few years with one drive only (and with backup to the cloud). Recently the NAS reported that the drive has errors, and now the health status says the HDD is dead. I have been able to recover most of the data by pulling out the HDD and connecting it with USB adapter to my Pc, but with more than 80.000 files recovered without file names and folder structure this is almost useless. But at least this proves that the drive is not completely dead.

 

The NAS claims that it is set up as RAID-2 with two drives, although I've never made that configuration. Just wonder if that could be some of the reason why the NAS refuse to let me access the drive?

 

Any ideas to how I should start my trouble shooting?

  • BTW, the drive problem has come gradually, in such a way that the files and folder also gradually disappeared without me noticing this. The result: my cloud backup service has also removed the same files, assuming the files we're deleted intentionally. Since the cloud service only keeps deleted files in the archive for 30 days, they got permanently deleted before I knew there was a problem... This is why I have tried to recover my files the hard way.

      The NAS doesn't do RAID-2 (actually no one does).  Perhaps you were thinking "XRAID2".  The "2" in XRAID2 doesn't mean 2 disks, it means the second version of XRAID.  It's the default RAID on your NAS.

       

      The NAS declared the disk dead because it had too many errors, not because of the RAID configuration.

       

      On file recovery - Netgear offers a paid file recover service that you could try ( https://kb.netgear.com/69/ReadyNAS-Data-Recovery-Diagnostics-Scope-of-Service ). Some users here have posted sucess with ReclaiMe.  You might want to clone the drive, since it might degrade further.
