Need help with WNDR3700v3 and Seagate Slim Backup Plus 1TB

Router's main purpose is routing so users can share Internet and files between themselves. Likes of USB port or eSATA port

is just a secondary thing. USB 3 has shielding problem and known to have inherent noise problems. When some people call USB

drive attached to router a NAS, I have to wonder. Real NAS is a computer on it's own with it's own OS which performs many

different tasks. I just leave 64GB flash drive on USB port as a scratch pad. I have Synology NAS running 24/7 .

It does not mean non-listed drives won't work. There will more which will work, If one want to use a USB attached drive as storage

facility better have self contained 2 bay enclosure which will do Raid 0/1 or JBOD set up. I had 3700 LONG time ago. I favorite f/w

for it was Trondah's OpenWRT with Luci GUI. I go thru average 2 routers a year getting newer ones for testing and review at

no cost to me. Every one of them worked. Some are easier to manage and control, some are little more difficult. But all worked for me.
