ReadyNas Duo+. I updated the firmware to the latest 5.3.11 and on reboot of the NAS one of the drives(volumes) is not recognized and the blue light is flashing. I was able to reboot the NAS and do a volume scan, but it did not come back.What options do I have here? Is there some way to attach the drive to my Win7 PC and run some kind of recovery program on it? Is there something I can try on the NAS itself?

What status does RAIDar show?The v2 should still be under warranty - did you contact Netgear support?

The NAS box itself appears to be fine. It's a failed drive I'm trying to recover data from.

You could try to clone it.Netgear support does offer data recovery services, but they are not free.

I was hoping for some kind of shareware/freeware data recovery.This is the email sent to me:***** File system check forced at Mon Nov 10 12:03:14 PST 2014 *****fsck from util-linux-ng 2.17.2e2fsck 1.41.14 (22-Dec-2010)fsck.ext4: No such file or directory while trying to open /dev/c/cPossibly non-existent device?e2fsck 1.41.14 (22-Dec-2010)Pass 1: Checking inodes, blocks, and sizesPass 2: Checking directory structurePass 3: Checking directory connectivityPass 4: Checking reference countsPass 5: Checking group summary information/dev/mapper/d-d: 16132/30285824 files (28.2% non-contiguous), 343523523/484573184 blocks

I don't own a v2, so I have no recommendation on tools that work with it. I do know that linux reader will not work (though it is the easiest option for the duo v1).

All drives are SMART enabled these days. I'm disappointed there was no warning. Surely for something like a NAS it could interrogate the SMART data and return if the reliability of the drive is degrading. To go from functioning to paperweight with a single reboot seems unncecessary to me.

You don't always get a warning from SMART errors that a drive is failing.

So you got no emails about SMART errors? IF you check the SMART stats of the disk does it show a problem?

No email warnings from the NAS. Right now, I'm moving data from the remaining good drive to a windows mounted drive. Once that is done, I'll take out the drive, try to find an NFS2 driver for windows and see what's left on the failed drive.

You can also see the SMART stats on the windows system (even if it doesn't recognize the file system). Acronis drive monitor is a freeware package that will do that.

Thanks Stephen, I'll take a look.
