Thread: Pioneer Premier DEH-P600UB with Western Digital Hard Drive

But the deck power is "always on" because of the clock. (in a manner of speaking) And being that it is "always on", it is constantly powering the HD even when in the "off" position. The only way that I can fool it, is to not have the HD hooked up to the USB port. See what I mean?

I'm just trying to find a way around having to hook it up manually every time.

But still can't understand why it shuts my deck down randomly. It could be working fine for a half hour, then stop. I'm puzzled.

hmm...maybe.

The owners manuel says that it accepts most all mp3 music players and mass storage devices, so the compatibility shouldn't be an issue.

Power consumtion may be, I guess. But that doesn't make alot of sense to me either. It's drawing power from the alternator, which should be more than sufficient I would think. It powers my 500watt and 300watt amps fine. Same with all my off road lights.

The one thing I read in the manuel that raised an eyebrow was that switching your ignition position may affect it. That could explain one thing, but not the shutting off the deck. Hell, I don't know.

Any input is welcome.

That makes sense Paul, thanks for that. I know what you mean. I have a 500GB next to my tower that I KNOW would be of no use in a vehicle.

But the Western Digital HD I'm running is smaller than my hand, thinner than a pack of smokes, and is USB powered only. So it kinda throws that out the window I guess.

It starting to seem that I might just be forced to put up with it unless anyone can figure it out. I WOULD just use a standard Thumb Drive, but I think they only go up to 16GB, and that won't fit all of my music on there @ 320kbps. There might be some 32GB Thumbs out there now, but they are probably still pretty expensive. The 160GB HD that I'm using only cost me $60 so I thought that was the better route to go. It works great with my PC, just having these little problems with the Car Stereo. I hope I can find a way to solve them.

I'm wondering if I have a reset button on my HU, and if that might solve the problem??? If I remember correctly, I didn't start having these issues until AFTER I started switching the SOURCE over to radio at one point. To be honest, I don't even listen to the radio really, I just wanted to see how clear the stations would come in on the new HU. What do you think?

Here's a couple pics of that HD, and I'll post a link for my HU.

your headunit is not powering your HDD properly. Notebook HDDs (2.5") require between 0.7 and 1.0 A. A USB port supplies a maximum .5A. This does not mean that the USB port on your headunit will supply this much (it may be significantly less). Thumbdrives use about 0.05A. Maybe the reason your headunit is resetting is because the HDD is causing a surge on the USB port as it spins up. It's similar to getting a surge on a USB port in Windows and Windows tells you you need to reset the port. Bottomline: If you want to use the HDD you will have to find a way to power it other than from the headunit.
