I was wondering does the DNS-321 support the Time-Limited Error Recovery (TLER) feature? I have two Western Digital 500GB Green Power drives (WD5000AACS) and planning on running RAID 1 configuration and these drives do not have the Time-Limited Error Recovery (TLER) feature so I just wanted to confirm does DNS-321 does or does not support or have this? I believe this is one of the tested and and supported hard drive for the DNS-321 also?
