I TAKE IT BACK - I ONLY RESOLVED THE SYCH ISSUE FOR VOL 1.
The Vol 2 still has a problem that the HD constantly trashes 24/4.1) The synch issue turned off my network traffic. I opened the win 10 control panel and in upper right box typed synch. It showed me the green and yellow ball labeled "Synch Center" - due to some unknown reason there was an ongoing synch set to the D-Link Vol 1. I shut it off and the network settled down and the Vol 1 light remained steady rather than showing constant blinking.
2) Vol 2 light still blinks 24/7 even when all clients in the house are turned off and the modem plug pulled - only leaving the router on. I finally pulled the Vol2 out of the NAS and plugged it into my Win 10 desk top EZ-dock and ran the Crystal Diskinfo program. This gave me a CAUTION, but I cannot read the SMART data, other than to see there is a caution on the "Reallocated Sector Count". So maybe the drive (which has 64301 hours on it) is going bad. Does the EXT2 or EXT3 formatting system do all of this inside the DNS323?
If I am going to be purchasing another terabyte drive I am also going with a new NAS that uses NFTS so I can read a bad drive on my Windows PC.
(I do not know how to INSERT a jpg that is located only on my desktop)
The icon "insert pic" only gives me the html code - am I supposed to insert the location on my PC? That doesn't make sense)Here is the data if anyone can help me read
