Fried(?) ReadyNAS NV+ #19179228
I have a ReadyNAS NV+ (3x500GB) that has performed without problem for five years. Yesterday morning I left it unattended while copying a large file to the device from a WinXPPro machine. When I ret...
Those were my symptoms. In my case, though it took a few days, tech support advised me to test the drives using Seatools, downloadable from Seagate at
http://www.seagate.com/support/downloads/seatools/
I did this from an oldish Dell running XP, using a hotswap external USB device, and though the drives were formatted by the NV+ the utility had no difficulty running at least the basic, generic, non-destructive tests. That identified one drive (a Seagate ST3500320AS, a model that is in the HCL but in my experience had already failed once and been replaced in this device) as bad. Tech support then advised my to reinstall the remaining drives, which I did to their original slots (2-3). On the first restart the NV+ hung. So I powered it down and tried again (see below for why) and it came up with all data intact in a non-redundant array. On adding a fresh drive to slot 1 it resynched in a couple of hours and is more or less back to normal. Tech support wanted to see the logs, which indicated in the two weeks preceding the power supply failure the failed drive had been accumulating reallocated sectors, to which T/S assigned the drive failure. I am not so sure that the P/S failure had nothing to do with it, as the drive had not failed before that happened. But that is less important to me than recovering the data.
Before any of this happened, I had on my own removed the existing drives and installed a single fresh 500GB Seagate to see if the machine would restart. Much to my dismay it hung again on start up. Having nothing better to try I powered it down and then restarted it again, and it came up fine. So it may be that something in the firmware or O/S makes it more able to restart after some event of failure after a couple of tries. If you do this you should be able to access the device via frontview, from which you can take a look at the logs and see if one of your drives is experiencing a problem. I'm not that conversant with X-Raid, but I infer that if only one drive has failed you stand a good chance of recovering your data by reinserting the still-viable drives in their original slots.
This strikes me as perhaps easier than trying to mount the drives in a different machine with a different O/S, but chacun a son gout.
Hope this is of help.
