Hi,
I've been using my 323 in Standard with 2 disks (seagate 500) and backing up from one to the other. I've been doing this for a number of months with no problem. I'm not using any plugins or modifications, and have recently upgraded to 1.6. I've got a 3rd disk of the same type, with the intention of once every few weeks switching a disk and keeping the 3rd one at work, so that if anything goes terribly wrong I've always got an offsite backup with maximum a few weeks loss. I seem to have a problem swapping disks, after doing the following:
I switched one of the old ones (vol2) for a new disk.
I removed the one I want to keep (vol1) so as not to risk formatting it
I switched on the 323 with only the new disk inside, and formatted it (choosing Standard). and it was fine, showing one empty disk in standard.
I powered down, and reinserted vol1, and powered back on.
I was prompted to format both disks, and chose to 'skip'
The problem is that although it reconsies there are two disks, it is now showing as having only one volume in Raid 1, even though I never asked for this. my information is all there, but I want it in standard, the way it was, so that I can backup between the two and occasionaly replace one of them.
How can I fix this?
Thanks!

The issue is that you are trying to use the DNS for something it was never intended to do. There are configureation files stored on each disk and in the flash memory (2 locations) inside the DNS. These files tell the web utility how the system is setup and what the serial numbers are for each disk. By swapping disks in the manner you are doing, you are getting mismatches between the information stored on each drive and in the flash. The unit is expecting to see a specific disk (as is the other disk). Since it is seeing something other than what it expects, it is prompting you to set the unit up again.
What you are expiriencing is normal and fully expected.
The solution would be to stop doing what you are doing and get another unit for copying to.
Another solution is to fun_plug the unit, insert usb-storage.ko, and then connect the 3rd drive via USB and copy your data onto that. This is probably your most cost effective solution (and very easy).
Lastly, you could fun_plug it and make some custom scripts for changing the configuration files when you are going to swap drives around. This is probably the most difficult, and poses some risk of data loss / corruption if done incorrectly.

Thanks for the reply.
just one other question - if I keep it in Raid 1 setting, would I then be able to periodically replace one of the drives and have all my data safe on the one I removed?
And if that doesn't work, then -
I know everyone on this forum will find it silly, but I've been scared of taking the plunge and going the fun_plug route... perhaps needing to follow your suggestion will finally push me into the water...

Same problem, only worse. Removing a drive is not the issue, it is how the DNS reacts to putting another one in.
fun_plug is, for the most part, very safe. I have been using an older version of ffp 0.5 for some time now. If you only want fu_plug to acomplish what you described, then you can do so without too much concern for losing your data. Obviously, if you start modifying flash, or deleting thing, you can screw things up, but something basic like ffp is great. You really do not even need that. A simple fun_plug that inserts usb-storage.ko, and mounts a USB drive is really all you need. You do not even really need telnet access, although it makes it significantly easier to copy your files. There are ways around that, too.
The nice thing abot fun_plug is that it is stored on the hard drive. Erase the file or remove the drive and it is gone. There is no actual modification to the DNS F/W.
