I did what I figured should have been a very simple and straight forward thing - added a 2nd drive to the DNS323 which had been running in the default standard mode. I had one Hiatachi 2T in the left slot and wanted to add a WD 500GB drive into the open right slot and wanted to leave the system running in the simple standard mode. Therefore no raid - just two seperate drives that would be indpendent of each other. Read the manual and based on that shut down the device, plugged in the new drive into the open slot. Restarted unit, logged in. It saw the new drive and displayed the screen shown in the manual. It had a next button to continue and text stating "Your new second hard drive will now be formatted. The existing hard drive will not lose any data". There was also the box to check if I wanted to "Reconfigure to Raid 1" Since I did not want that I did NOT check the box. As soon as I clicked the continue button the next screen shows up showing the progress bar of the formatting process. Unfortunetly it also has the following text at the top: "This section allows you to setup a RAID configuration on the selected hard drives. Please note that the data stored on the drives will be erased during the formatting process". WTF -Not what I wanted to see. The formatting proccess had already started automatically when this new page was displayed. There was a "skip" button at the bottom right corner. The manual did not mention this at all having stopped at the previous screen. Since I know I did not check the box for Raid config on the previous screen and not sure what clicking the "skip" button would really do, especially since the formatting had already started auotmatically, I just let the process finish. It finished and upon rebooting and logging back in I saw the following: The original hard drive was not formatted and still has the data on it. So it was in fact NOT reformatted. Going to the Tools > Raid screen I see what seems to be confirming that the drives are not in Raid setup. Under "Current Raid Type" it has volume_1 = standard, volume_2 = stanard and a button you can click that says "Set raid type and re-format". So it looks like everything worked out ok, but D-Link needs to correct that screen that scares th S**t out of you. If you do everything per the manual you should not be seeing that. Very basic and simple thing that D-Link should correct ASAP. Of note, the system actually relabled the origial drive from volume 1 to 2 and made the new drive volume 1. Not sure why it needed to do that or if it's going mess up the mapping of that original drive.
