After upgrading to the newest firmware on my AC68U I noticed that my 3T drive is not mounted but working fine. Is this a fixable thing or anything to worry about?
Not sure it helps but I have a WD 2TB My Passport Ultra HDD plugged in to my RT-AC68U USB3 port and running latest Asuswrt-Merlin 380.65 Beta firmware and mine mounts fine and can be accessed via DLNA (tv) and SMB (macbook pro) without issue. Maybe plug in to your computer and and do a chkdsk (disk error check) either that or maybe an issue with detecting 3TB+ HDDs.
