Just purchased a D-Link DNS-323 2 bay SATA unit.
Have put a pair of Samsung 500gb HDDs in it.
Configured 300gb Raid 1 & remainder 400gb JBOD.
I'm using the RAID 1 portion for back up of important data.

Question please...
In MS explorer it is showing as 2 drives 300gb & 400gb (OK so far) so I assume the other 300gb unaccounted for is the RAID 1 mirror drive
Is there any way I can confirm that data is actually mirrored on both drives?

Sorry but I haven't had any experience with SATA or raid drives (current PC still on IDE)
