ReadyNAS Duo - new disk displays Bad Disk Detected in RAIDar
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 D...
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.
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 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.

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.
