ReadyNAS: lost data after removing a drive : case #17927967
Details are in the support case. A friend was interested in the build quality of the and removed one the drives and put it back. I experienced errors (in the support case) which I managed to resolve b...
Not knowing the nature of the problem, I can't say whether or not data will be recoverable in this case. I am saying that you took a big gamble. Playing poker with your data isn't a good idea.
Hot-swapping is designed for replacing failed disks or disks you no longer wish to use without downtime, not for experimenting to see how RAID works (though you can do this if you wish, but doing this without a backup is very risky).
Disks can and do fail at any time. Having said that there are a range of other problems that could have occurred (some more serious than others) and support can diagnose the situation to get a definitive diagnosis. The important thing is that making changes to your NAS will only make it less likely that data can be recovered. RAID is an enterprise feature that has come to home devices. It is a useful feature for home users. NetGear has designed the ReadyNAS to make it as easy as possible for home users to be able to use this. They do clearly warn in the manuals (http://www.readynas.com/docs) that data should be backed up.
The disk you removed and added again would have been wiped not the other disk. Until the resync completes when you add a disk, the array would be non-redundant. So a problem with a disk during this vulnerable period could result in the NAS to go into life support mode.
Updating the firmware or doing an OS re-install when you have a problem like this is not recommended unless specifically requested to by support. Basically the fewer changes made to the system while you can't access your data the better.
