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...
As I said before I didn't 'experiment' with the device. My landlord (who is a friend of mine) paid a visit to my flat while I wasn't there. He explained the situation but should have known better as we are both programmers. but that doesn't change the situation does it. That being said I really can't believe the result of this to be honest. Basically the unit has corrupted itself. It is hardly as though the external situation / sequence of events is that complicated that it couldn't deal with?! And to boot it could have destroyed one of my drives.... Great
In response to: "Well disk 3 appears to be dead (light not lit) and disk 4 has a huge ATA count which indicates the disk is pretty much dead", is that what the error message I posted would indicate? It is a ReadyNAS Duo v2 with 2 disks in it so unless disk 3 and 4 apply to partitions I'm unsure how that would apply. The lights are alight for both drives and do not flash or indicate any issue. Yes, disks can and do fail at any time but if it has failed and is not dead due to what happened then that is complete unacceptable. A hot swapping feature that trashes drives. In any case, that hasn't been confirmed to be the issue yet.
In regards to backup I consider having a second hard that is being replicated onto a form of backup. In reference to the manual: "Data can be lost due
to a number of events, including natural disaster (for example, fire or flood), theft, improper data deletion, and hard drive failure. By regularly backing up your data, you can recover your data if any of these happen to you". Improper data deletion is obviously a user error, fire a theft is obviously going to result in a loss of data although I don't keep spares of everything I own and leave them at remote locations in case there is a fire or it gets stolen. That leaves the third, hard drive failure. I thought a solution to that was buying a second drive that was replicated to from the first one. Apparently not. Given my scenario there was no hard drive failure. The system has failed and that has resulted in a loss of data.
So you can't say whether the data can be recovered or not.... Or add anything of value. You would prefer to post about the do's and don't's of backup routines. Thanks for the input.
