My Duo has been working fine with the one Seagate 500 gb drive that was originally included with the unit with purchase. I wanted to add a second disk for redundancy. I purchased a Western Digital 500 gb SATA 3 1/2" drive, and mounted it in the housing. I plugged it into Disk 2 slot, and it appeared to be recognized and led began to flash. I assumed it was copying Disk 1. However, it did that for 48 hrs. I tried a few things, that I read in other forums. I was eventually able to see Disc 2 in Frontview, and it indicated it had no free space available.Next, I took out my Seagate Disc 1 and set aside. I placed the new Western Digital in Disc 1 slot, and performed the factory reset. Hoping it would erase all data it had some how accumulated from my previous attempts. Now I get the message in RAIDar indicating Bad Disk Detected. Any suggestions on how to Resolve this? Surely I didn't damage the drive by anything I was doing.By the way, the Seagate disk is still good - I do still have it removed and placed aside.Thanks,Cindy

I would remove the WD disk again and test it with the WD Lifeguard diagnostic on a PC.

I don't have the ability to hook to my pc... Pretty much a novice here. :(

OK. Try powering down the duo and move the WD disk back to slot 2 (leaving slot 1 empty), and see if it boots up that way. The slot number matters with ReadyNAS. If it boots: Confirm that your data is there, and also check the SMART+ stats on the health tab of Frontview. The stats that matter most are reallocated sectors and spin retries. If it looks good, put your Seagate back into slot 1.If it doesn't boot: You should probably assume the disk is bad. If you purchased it recently on-line, you can likely exchange it, with no questions asked. If you wait too long, you will need to RMA the disk to WD, and you will get a refurbished disk in return. The model might be different (and the size could be larger, depending on what they have in their spares inventory at the moment). WD should accept the ReadyNAS bad disk report at face value, and execute the exchange.cindygraeff wrote: ... I was eventually able to see Disc 2 in Frontview, and it indicated it had no free space available...I am a little confused about what you mean here (and what you did on the initial install). When you install a second disk for redundancy, you should see both disks on the same volume tab (volume C). The "xxxx GB allocated" on the volume tab should approximately match the disk size, and should be the same for both disks. What you will not see is free space available on each disc. The "GB allocated" is not telling you about free space; it is just telling you the amount of that disk being used in the raid array. If you set up Disc 2 as a separate volume (c and d tabs), then you aren't getting redundancy. If you are looking somewhere else on Frontview, maybe you can give us some more details.cindygraeff wrote:I don't have the ability to hook to my pc... Pretty much a novice here. :(Being able to run vendor diags is a pretty useful thing. One way that works with laptops (or desktops) and is very easy is to do: Pick up a SATA/USB adapter (for instance http://www.amazon.com/StarTech-com-USB- ... B000VS4HDM). This gives you a disk power adapter in addition to the USB connection. I've found that the USB connection works ok (though slow). Though since my laptop also has an eSata connector, I also picked up an SATA-eSata cable - so I generally use the power adapter combined with that.

I installed the WD in slot 2, leaving slot 1 empty. The blue power light is flashing once per second. All 4 of the green LED lights are flashing together in a 3 long, 3 short pattern. The RAIDar shows the 2 disk green, but the info says Corrupt Root. What's next?Thanks for your help, by the way.

What's next?Thanks for your help, by the way.You're welcome.If you don't have a current backup of your data (or your duo configuration), then I think you should remove the WD drive, put the seagate back into slot one, and make the backup(s).At that point you could possibly submit an on-line support case, and let Netgear sort it out. (If you do that, you should edit the title of the thread to include your support case number).Another thought is that after the backup step you could reinsert the WD drive, and see if it rebuilds it. Either way, please report back on your status.

You may have unplugged it too early. When performing a factory default with more than one drive (which usually takes about 15-30 minutes) it will synchronize the sectors of all the drives, even though there is no data and it can take 8+ hours. In Frontview during this time the indicator button at the far left will show blue, the indicator under the icon for the device (volume status), if I remember correctly, will be flashing and if you put your cursor on it, it will tell you the percent of completion. If that percent does not change over a period of hours, then something is wrong.

Thanks PapaBear... I booted up again with both disks inserted, and Started another factory default by holding the reset button in the back for 30 seconds..... Waiting on the two disk LED green lights to flash the second time.

Then I went to RAIDar, and got the green solid lights under Disk 1, Disk 2, and Fan. Info indicated to Click Setup, which I did. I allowed the default setting to remain to X-RAID and submitted. now on the RAIDar, the first box on left, is solid blue. The Vol. Disk does not have any lights in the box. The 1 and 2 and Fan have solid green lights. The Info states Installing.

If I hover the mouse over the green light under 1, it displays Channel 1 Seagate model number and 465 gb. When I hover over the green light under 2, it displays Channel 2 WDC WD serial number, 465 gb, and ATA Error Count: 34.

This is the way it was for > 5 hrs last night. It never passed the Installing, nor did the Vol. Disk ever display a light and progress.

Should I shutdown, remove the Disks and try to do a factory reset on each one independently?

Return de WD Harddrive and buy a Seagate.

Since you have been tried a factory default with only the WD drive installed, and got a bad disk error, I would then assume that the disk is bad and should be returned.

I do hope you have a back up of the data that used to be on the Seagate drive, unless you did not want to keep it. You have had it in the NAS and performed a factory default.
