There is only 1 thread that has most of the Guardain stuff in it, Sticky. We have just started getting these through here with in the last 6 mo.

You can transfer the OS form one HD to another. It does it automaticly when you cold boot or hot swap. The difference is, if hot swapped will start the resync, on cold boot it only transfer the OS. But for things to work corectly a few things need to be checked.
1. Stop the scheduler for SnapShots.
2. The AV if installed (optional on 4400) must be disabled.
3. The HW stores drive info in flashram, If diaster recovery is active. With snapshots disabled releases this info. Failure to do so will drop you into to recovery mode if you start swapping HD's around.

The os is copied across all HD. Transfer the OS from 1 unit to the other can only be done if all HD are clean on the destination unit.

Procedure.
source (newer os) = snap1
destination = snap2

1. power down both units.
2. remove all hard drives from snap2. You must erase these HDs, a quick format will work. But it can not show any part of the linux file system or it will not work. I recommend using the mfg HD utility. And select any OS but Linux for the quick format.
3. install the clean HD in the snap 1, position 2-4, your choice.
4. Boot snap1. Watch the hd led in front. You will see the new HD led come on a stay on for 15-50 sec depending on the speed of the cpu. This normally happens around the 4-5min mark on my 4500, so yours may take a little longer. This is where the OS is transfered over. Normally after 10 min it has completed. If the diaster recovery page comes up, the diaster recovery was not disabled.
5. Power down snap1, via menu. and remove the HD
6. Remove the rest of the HD's from snap2.
7. Install the HD from snap1 in to drive 1 position on snap2.
8. Boot snap2
9. once it comes up you can hot swap the remaining drives. You must now do the complete setup as a new unit.

I would search the units for the .GSU (OS) files. The OS is supplied on CD with the units. It is required if you have to use diaster recovery, no way around it. There is a HD structure change between some of the OS's . As long as your are doing a clean install you will not have any problem. You are required to have liesen for each NAS. The V4 OS is a lot more refined than v2 or 3. It will also give you full support for Vista and OSX.

Depending on the age of the snaps the cmos battery may be failing. Do not change the battery unless Phoenix32 (Andy) says it needs too. Once removed you will have to setup the BIOS to work correctly. Andy has done this on several units and can assist you if needed. But I think what you were doing was not taking due to the fact that the os resides on all HD. If it sees one different, ir restores from the others.
