DSM-G600, DNS-3xx and NSA-220 Hack Forum

Theoretically you can replace the disks one at a time without losing data on the remaining drive, however, as with any storage device, you really should have a backup of your data stored elsewhere.

That theoretically is like a disclaimer - let me put it this way - I've done it without any problems - I've swapped drives in and out of the DNS-323, probably a lot more often than many of you will ever do - and not yet lost data doing it.

BUT - that doesn't mean that the same thing will happen when you do it.

WHY?  Because in 30 years in the IT field I have developed certain habits, such as wiping disks before reusing them - which MAY be the reason I haven't experienced that "format the wrong disk problem" that others have reported.  Why do I do it?  Because 15 years ago I had a mirrored NetWare installation rebuild from the wrong disk - and no, I didn't lose anything then either, it was in a "learning lab" environment that I had created expressly for the purpose - and that in case you were curious, was why I've swapped as many disks in/out of my DNS-323 - testing to see how reliable it would be in given scenarios, before I start recommending it to small business clients.

By the way - reading your reply - I'm guessing you didn't see the other statement I made, which was - .

as this unit is use for my primary storage location I have nowhere else to be transfering 750Gb of data (atm anyway).

That statement tells me you have no backup.  That is something else that 30 years in the business has taught me, if your data isn't backed up, you are going to lose it.

The piece of hardware reliable enough to be a primary storage location, without a backup hasn't been invented yet, and don't hold your breath whilst waiting for it to be announced.
