I have a 1 terabyte wd and a 1 terabyte toshiba ext hd, I can plug them in my alpine car stereo and will not recognize but any flash drive will, this is on 2 different alpine systems in 2 different cars and also the stock/bose system in the suburban with same results. Now as I said any flash drive works in either vehicle, but not the hds. I noticed the flash drives acording to acronis are fat 32 formatted and the hds are ntfs, so i formatted 1 of them loaded music same result, no recognition. What am I missing here? Also note someone had mentioned a possibility of not enough power for the hds, so I had a powered usb hub i threw in the loop, same results, yes.
Thanks in advance, I know this is possible, im forgetting something somewhere.
