According to the most recent downloadable DNS-323 manual (v1.30), p.87-89, you can install one drive, then "add" another drive. If I read "between the lines", it seems to suggest that you can have the first drive in "Standard" mode, then transition to RAID 1 mode while adding a new drive by checking ON the "Reconfigure to RAID 1" option box. The manual shows a screen capture that reads "Your new, second hard drive will now be formatted. The existing hard drive will not lose any data." That seems pretty clear.
This, of course, goes completely against the proposed solution in this thread ... that is, the idea of removing the existing drive to format the second drive, then replacing the first. According to @keralihr, this remove-format-replace method doesn't allow you to "upgrade" to RAID 1 mode, preserving your original data.
So, my questions are:
1. Is the manual wrong?
2. Has anyone done this successfully without losing data?
3. (I realize the OP was begging trouble using v1.08, so) Has anyone done this with v1.09 or v1.10b7 ... how does it behave?
I ask because I'm still trying to deploy two Seagate ST2000DL003 drives in my DNS-323 in RAID 1 mode and am wondering if there's a way to add one drive at a time. I realize these drives are AFT and I intend to use v1.10b7 to format them.
Thanks all,
DH
