My DNs-323 has performed well for about 4 years now.
I have 2 x 1TB WD drives set to RAID type standard - individual disks.
Adding some downloaded .mkv files the other day, I triggered a manual refresh. This refresh took 3 days.
The drive contains around 175079 mb free. I use it to stream content over a wired lan to my Samsung TV.
I understand the more media added to the drive, the longer it would take to refresh...but 3 days Huh!!!
Current firmware 1.10
Any ideas ?
