Humm, yup, one of the FIRST things I tried was the power supply off the other M HD in the bedroom, along with the backed up files off it. I also have another power supply that's 12v but 3.0 amps and I tried that one also. I'm a "gear head" so the electronic testing stuff isn't here. I can build you a carburetor for your race car though.
My 3 systems are pretty much identical where sat locations for motor control, etc. is concerned. I can take any receiver I have and put it on any of my 3 systems and it will work.
The hard drives I've been using are a 120GB laptop IDE and a 640GB SATA drives and are powered by the receiver. The M HD in the bedroom uses a newer USB 3.0 to SATA adapter that works just like clockwork with that 640GB Hatachi drive I had the problem formatting a week or two back. I do have a couple of POWERED USB 2.0 enclosure types as well that I've tried on it along with a couple of different USB flash drives in various sizes and formats.
I do have one "similar" to what Toucan has but I don't have a 128GB SD card for it. I only have a 128MB card but I guess I could hook that one up to see if it would try to record to it?? Hummm................... or that 128MB may be too small to even test that? Won't cost anything to try it though, hey.
Ennywho, I'm just going to use it like it is and put up with the inconvenience of having to do manual records. That or use the other receiver for recording stuff and this horked up one for playback.
I do have options, one of which may be a Manhattan 1978 if I can get any decent feedback on them in my other thread??
Oh, and thanks everyone for the comments/suggestions.
