Hi to all,
I have DNS 320 with only one hard drive installed (2TB). Now I have bought another hard drive (2TB) and I'd like to use JBOD mode.
The wizard ask me to format the actual volume_1, is it correct? In this case I have to copy the actual file on volume_1 in another external hard drive....can you confirm this?
If yes, I have installed fun_plug, after formatting and replacing the "old" file form backup, fun_plug works or not?

Thanks in advance.

Answering the first part of your question, if you change the HDD configuration (e.g. Standard Volume to JBOD), then all data on the existing Volume will be erased. You will need to make a full backup of your data prior to performing the configuration.

Many thanks JavaLawyer,
another question: if one hard drive broke, after the replacement with a new one, I have to do the same operation? I have to backup the existing data and reformat at all?

Thanks.

A single HDD failure in a JBOD configuration will result in a loss of all data across both HDDs

Please see the "ShareCenter - Best Practices" section of the following sticky post for information on different ShareCenter HDD configurations. I don't discuss JBOD explicitly, but the the information is relevant nonetheless: ShareCenter - Important Posts & Information

I couldn't find the "best practice" under the DNS 320, so I'll post my question here

I will be buying additional hdd for my DNS320, it came with a standard hitachi 1tb, but I don't like the idea that my current hdd might be formatted when i insert a new hdd, so I would like to know how to avoid that. (if possible)

Can I assume from your statement that you DO NOT have a backup of the data on your disk?  If that is the case then the first thing you need to do is make one.

Depending on how you have setup the disk that you have and what type of setup you want for the new disk the options for formatting will vary.  If both disks are to be standard and your original is formatted as a standard disk then you should be able to format the new disk as standard without problems - just make sure you select the correct disk (most problems come from finger trouble, clicking on OK before checking).

Awesome, thank you for the input. I will actually invest in a 2tb back-up external USB harddisk, just to back-up what I consider "irreplaceable" before toying with 2 x standard harddisk.

EDIT: bought a Toshiba DT01ABA200 2TB and will proceed to format it standard format.

EDIT2: ok, so my DNS320 couldn't format the Toshiba 2TB while I had my Hitachi 1 TB in at the same time. I couldn't enter access my data either, so I took out the Toshiba and kept the Hitachi in, and I had access to my data once again.

Which means I had to take out the hitachi and insert the toshiba in order to be able to format the 2TB in the type/style DNS320 prefers. Once it's done I will try removing it. and insert hitachi again to check access to the data, and then I will insert the Toshiba.

My only worry is that DNS320 calls the Toshiba same name as my hitachi (Volume_1), I will try changing the name before I insert the hitachi.

EDIT3: ok, it worked, my Hitachi has until today always been Volume_1, but now it's called Volume_2, both are standard formatted. I will try this setup (JBOD I think) for a while.

EDIT 4: I made the new harddisk available on my home network, and had to run a rebuild. After that I had trouble figuring out how to move data from one harddisk to the other, until I "fell" over Application => Web File Server. with that it's possible to move or copy folder/files to the other harddisk. I'm currently moving a little bit at a time. I haven't had luck with making the UPnP work, can't see any of my harddisks when I access it from my mediacenter, however I access it as if it was SMB, which means I can see both hdd.

Been using my new harddisk for a month now, and the noise level hasn't increased. I think it's pretty safe to recommend the Toshiba 2TB DT Desktop series PA4292E-1HL0
