Duo won't boot, how to proceed?

Hi. I've been getting error emails for some time that disk 1 in my duo was getting increasing SMART errors.

Now it will not fully boot; the power light is steadily blinking, the green disk light for disk 1 is solid green and the LED for disk 2 is blinking.

RAIDar says it is doing a "file system check, 100%" but has been stuck there for a few days. I've tried pulling the power twice and turning it back on, it just does this exact same thing.

Should I remove disk 1 (the one that is probably now dead) and try to boot the NAS? I'm just concerned because I would think the LED for disk 1 would be blinking or off, but the LED for disk 2 is blinking.

Also, of course I have all the contents backed up to 2 USB drives - can I plug those drives into my Ultra 6 and read the contents? I believe the drives would have been formatted as EXT3.

Thank you

    Nope. Can I just pull it & see if the NAS will boot?

    Well should I do this?

    Are there any other options?
  • I removed both attached USB drives (should I also unplug the UPS from the USB port?) and tried the skip file check, still won't boot completely...
  • Ok, removed disk 1, booted up, and it's back up!
    Now I have to decide if I want to replace the disk or what, as I'm looking at building my own NAS....

    Double-checking now that all the data I want is backed up to USB.

    Thanks for all the help.
