NV+ disk#4 uninitalized

Which log? Can you post an excerpt from that log? Disk 4 is typically the parity disk (assuming you last did a factory default with all four disks in place and are using X-RAID)

The device lost power on Sunday and now have some major disk issues. I know that disk #0 or slot #1 is bad. Also i thought that disk #1 or slot#2 was bad so i created an image of it with acronis incase i had to recover it. I tried putting a know good drive back in slot #1 and it wouldnt rebuild so i started looking at the logs and found that disk #3 slot #4 is showing faulty in the logs ( shown below). So i took that drive out and was going to make an image of it also so i could recover it to another disk but disk shows uninitialized. So i assume it lost its MBR or partition information. I figured if i could get this disk repaired and it boots it would put the raid back online and then i could recover my data .

PHYSICAL_DRIVE: 3: DISK<N:3/4,hdi(56,0),ID:3,PT:1,SZ:2930256688,ST:P :faulty>

If you would like i could post a full copy of the log or email it

As I said disk 4 is typically the parity disk. It is normal for it to appear uninitialised. However from what you posted it looks like there is an issue with that disk. Have you tried testing it using vendor tools (e.g. SeaTools if it is a SeaGate disk)?

So you don't have an up to date backup?

I'd suggest opening a tech support case and working with NetGear support on this issue. You can send the logs zip file to them when they request it (or if it is an online case, attach the logs zip file to the case). If over 90 days since purchase make an online submission to NetGear.

Thanks for the response I have opened an online case this morning as this device is over 90 days old. I wasnt able to find what the SLA was for online cases by chance do you know ? And of course I have no backup. I had another NAS that i was rebuilding and moved the data to this as a temp holding spot and how this happened. Typical !

I am going to run the SeaTools on the drive tonight to see what it brings up . I did the short test and that passed (currently running the long test)

So do you think i should try to mirror this disk #3 , slot#4 to another drive ? I just dont know what application i could use as when i tried Acronis it shows do paritions on the drive and the space being unallocated/uninitalized

What i just dont understand is when i have all 4 disks in the NAS the NAS will not boot. It just gets hung at booting though when i take out drive #0,slot#1 it will boot but put the RAID offline. Is something linked to disk #0 slot#1. And the log allways shows disk#0,slot#1 online even when the disk is removed as shown below. I only had disks in slot #2,3,4

did the long test overnight and everything passed 100% on disk#3,slot4.
