RND2000-100NAS fail
After several years my RND2000-100NAS appears to have failed. Yesterday I could not access it and found it was completely dark, no lights. It would not power up. I verified AC power was good and veri...

if you are using xraid, you can get the data off using linux reader-connecting the data drive to a windows PC (http://www.diskinternals.com/linux-reader/)
Usually the data disk is in slot 1 (leftmost) and the parity disk is in disk 2. So try disk 1 first. If you don't see the data volume, then try disk 2.

Thank you very much Stephen! I installed the software you recommended, removed the drive from slot 1 of the ReadyNAS, put it in an external drive enclosure, and was able to recover almost all of my files. My backup files are unrecoverable for some reason but it appears I was able to recover all other files.
Your advice was a lifesaver, thank you very much. Based on this experience I will no longer store irreplaceable data on a ReadyNAS. The redundancy of RAID protects against hard drive failure but I hadn't considered that failure of the ReadyNAS unit itself would result in a situation where I am dependent on 3rd party freeware that may or may not be able to recover my data.
Thanks much for the help Stephen!

You shouldn't store irreplaceable data on any single device, no matter what that device is.
Backups are vital.

I'm glad you have gotten your data off. There are other ways- in particular you can mount the data volume on a standard x86 system. This is a bit more complicated, esp. if you have no other linux systems or are not familiar with linux.
In general: RAID Redundancy is primarily about availability (that is, data remains available to users during routine disk replacements). It doesn't fully protect your data from loss.
No matter where you keep your data, its important to have backups - otherwise will you lose it at some point, it it just a matter of when.
