Hello, I have my unit setup with Raid 1. The unit seems a little buggy and I am worried about my the unit crapping out and even though I have two disks, loosing everything.
Anybody have a comment on this?
But my real question is this:
I copied some data to the drive, then popped it out and mounted in linux to see if I could access the data in an emergency, just to see if it would work. It did.
Then I popped it back it and it said it would take 400 minutes to rebuild.
Now it finished and here is what it says
Stock firmware 1.4
Volume Name: Volume_1
Volume Type: RAID 1
Sync Time Remaining: Completed
Total Hard Drive Capacity: 979745 MB
Used Space: 54330 MB
Unused Space: 925414 MB
Volume Name: Volume_2
Volume Type: JBOD
Total Hard Drive Capacity: 7415 MB
Used Space: 4 KB
Unused Space: 7415 MB
My question is 5 fold.
1. So what is Volume_2? Why do I have it? Should it be there?
2. If I pop a drive out for a month and then put it back in what exactly would happen?
How does it keep track of the good disk(with data your data on it) v.s. a disk that you just throw in there?
3. So when it detected that I popped one drive out, does it just scan sector by sector and copy from the one to the other?
4. How do I really know my data is secure and mirrored and identical?
5. I suppose I could shut the drive down and run a utility to make a checksum of the drive data on each unit individually just to see if everything is working? Will this cause any problems? Has anyone ever done or know how to?
Can anyone comment?

1. If you build a RAID drive using less than the available space, the DNS-323 creates a JBOD volume with the remaining space.
2. The unit should rebuild the array - it may or may not rebuild using the current data - to guarantee a correct rebuild you need to insert a new or clean (no partitions) disk.
3. I'm not certain but I believe a sector copy.
4. Good question - you don't.
5. I suppose, you could, I have no idea, and I have no idea.

This is why you back it up - RAID is not intended to be a form of backup.
