I just bought a refurbished 2Tb and have been 99% happy with it. Yes, it takes some getting used to and it definitely is not for the technical novice, but I have been happily ripping CDs, listening to online radio and so on with very little trouble.
Well, that "very little trouble" is true *as long as I don't plug the included WiFi antenna into the USB A port.* When I first took the device out of the shipping box, I plugged the antenna into USB-A and had all sorts of problems, the worst being the "Read-Only HDD" error and the dreaded "flashing red/green" error. Thankfully both occurred before I started ripping CDs and I was able to wiggle out from under them.
Just for fun I moved the antenna to USB-C and everything has been perfect. However, whenever I experiment by moving things back to USB-A, the whole thing goes right back in the crapper again.
So my question is this: is this problem a function of (1) I should not be using USB-A for the WiFi under any circumstances, (2) there is perhaps a flaw in the device itself, and/or (c) I should be running on Ethernet in any event.
Again, let me stress that using the WiFi antenna in USB-C yields flawless results. I have not yet run a backup or anything else that requires USB-C, but I expect that it will work OK.
Any feedback appreciated!
