Duo v1: Dead volume

Am I correct in assuming that (a) the volume frontview and RaidAr say is dead, is not recoverable, and (2) that the data which was Raid-2 protected to the second still has a copy of my data?

Thanks!

  • There's a possibility that your data can be recovered. It depends on what is really going on with your device. Did you have drive failures? ATA/Reallocated sectors? If you were protected with X-RAID, you can lose 1 disk and still have all of your data. If you lose both disks, you would lose all of the data on that device.
  • My second disk does still have my data- do you know how I can determine how the drive failed? All frontview says is dead.

    Thanks!

    Since you can get to Frontview, Download the logs via Status > Logs > Download All Logs, then put in in a dropbox and send me a private message on the forum and I will look at them for you.
  • Disk 1 appears to have failed out of the RAID.
    According to these logs, it still detects your volume, so you should be able to access your volume and data.

    I'm going to recommend at first to reboot your unit. It should re-detect the disk. From what I see here, you're using green drives, but the drives look fine to me. Green drives tend to drop out of raids because of their slow spin up time. Your first disk's start up time was 6300 while the second one was 3825, so the times were a little different when it came online. If it doesn't re-detect the disk and put it back in the RAID, turn off the unit, pull disk 1 (Device Model: WDC WD20EARX-00PASB0 Serial Number: WD-WCAZA8307523 <<< verify this disk serial) start the unit with disk 2 only, then pop disk 1 back in the unit.
  • OK, I'll do as you recommend, and see how that goes- thanks for your excellent support!!
  • Unfortunately, this is not working... still getting dead status for this disk...
