Lost all my data on my RN104 - anything I can do?
I've got a ReadyNAS 104 that has lost all my data. After receiving an error message that stated one of my drives was having issues, the front panel locked up but I could still see my shares and files...
I don't accept your conclusions at all.
Firstly none of your disks are on the compatibility list (http://kb.netgear.com/app/answers/detail/a_id/20641). You could have run into issues directly related to compatibility issues with the disks you are using. Using Green disks is not a good idea (however those are the two disks that seem to still be O.K. of the four you have installed).
I just had another look and one of your disks had a reallocated sector count that has increased to 50 ages ago (if you download your logs you can see this in smart_history.log; note I have removed the serial numbers as those should not be posted publicly)
If the reallocated sector count increases regularly, rapidly or reaches 50 we'd recommend replacing a disk. A non-zero current pending sector count would suggest a disk should be replaced. Though the count has not increased recently this disk is not in good shape and it is one of the two disks that dropped out of your data volume array.
The disk you have been getting errors about recently should have been replaced last year. The current pending sector count was non-zero when you first installed it.
If you leave disks that are clearly failing badly in the system for months after you're aware of that you are asking for trouble. Whilst they may not be completely unresponsive these disks clearly needed replacing. Now it is too late for that. It's data recovery (which may be unsuccessful) or restore from backup.
It looks like at least one of your disks (the SeaGate disk) was used when you added it to the NAS. It is better to use brand new disks rather than reuse old disks.
With external USB drives if the external USB drive fails you lose all the data on it. So you would need to keep another copy of the data if you used those too.
No important data should be stored on just the one device.
If you are at all in doubt as to whether a disk should be replaced, how urgent it is to replace etc. it is better to ask. The community is here to help. We like to help as best we can to try to avoid disk problems leading to bigger issues but once they have led to big issues there's not much the community can do to help.

If you leave disks that are clearly failing badly in the system for months after you're aware of that you are asking for trouble. Whilst they may not be completely unresponsive these disks clearly needed replacing. Now it is too late for that. It's data recovery (which may be unsuccessful) or restore from backup.
It looks like at least one of your disks (the SeaGate disk) was used when you added it to the NAS. It is better to use brand new disks rather than reuse old disks.
With external USB drives if the external USB drive fails you lose all the data on it. So you would need to keep another copy of the data if you used those too.
No important data should be stored on just the one device.
If you are at all in doubt as to whether a disk should be replaced, how urgent it is to replace etc. it is better to ask. The community is here to help. We like to help as best we can to try to avoid disk problems leading to bigger issues but once they have led to big issues there's not much the community can do to help.
