i have just setup my DNS-320, no problem seeing the drives, although I found it odd that on first format it did them as standard not raid1 as per my request....anyway.
now I have Raid1 setup, what happens if I remove either drive? will it just copy the data from the other or will it leave it be?
only reason I ask is I want to see what happens if I try to access the data held on the drives in an external usb enclosure, just in case the nas fails, not moving loads of vital information (pictures etc) onto a raid configuration until i know its retrievable (somehow)
thanks in advance
ps, i assume this is hot swappable providing no read/writes are taking place

I wouldn't like to try hot swapping the drives.
Yes you can unplug one of the drives, with the NAS switched off, and put it in a spare SATA slot in your computer or into a USB/SATA caddy.
Now, if you are running windows the fun begins. You need to get an installable file system driver that will allow you to read Ext3fs - without it you will see nothing.
If, on the other hand, you are using linux then you should be able to read the drive with out problems.
If you remove a drive and then reinstall it the drive that remained in the unit will act as the master and its contents will be copied to the other drive.
-
the contents will be copied across even if the data is the same?
-
That's a good question. I don't know if it will have to rebuild in that case.
If you try, please tell us!
-
how would i know, would it tell me it needed rebuilding?
-
Yes, under "management" > "disk management", it will tell you "Volume_1 : RAID 1 (Completed )" if everything's fine, or "Volume_1 : RAID 1 (Degraded )" if you need to rebuild!
