Just to make absolutely sure, I ended up doing this a few times. When I just deleted the partitions and quick formatted them and put the drives back in the DNS-321... the file i had put on the drive was still there, and they were both seperate partitions still.
I just finished a full format, put the drives back in the DNS-321, and so far the format just isn't working (freezing again at 94%)
These drives were brand new, right out of the box.
When formatting the disks, it says the maximum format size is 748gb, instead of ~698gb (advertising GB vs actual GB, or however you want to call it (10^9 vs 2^30)), so no clue if that matters.
I've tried keeping an IE window/tab open to the administration page and refreshed the screen so it doesn't log me out of the administration control panel, along with just leaving it alone to do it's thing.
Also, just noticed that below the status bar, starting somewhere between 20-30% one of the frames in the popup (using the Tools -> Raid method) shows an "Internet Explorer cannot display the webpage" error, but I am not sure what page it is trying to load.
Firefox 3 (Safe mode) just freezes at 94% too, with no error message.
Tried in the initial menu (log in and it automaticailly prompts you for format type) as well as in Tools -> Raid
Computer: Vista Home Pro, using IE7, Firefox 3 (in safe mode), both the PC and the DNS-321 are connected to a gigabit switch. I do not have any spare SATA drives to throw into the DNS-321 for additional troubleshooting.
Let's see... any other information I am missing?
