First of all, has it been established that there are NO 2.5" drives that can work off the 6900 with no external power? Perhaps one of the more power efficient ones like the Samsungs?
Second of all, is there anything about that Seagate that makes it better for the 6900 than other externals (or buying a bare 2.5" drive and putting it in an enclosure)?
Third of all...how are you all liking your 6900's? I think the USB functionality is really great. But I find the UI to be quite unintuitive. Also I'm not sure that I am happy with the SQ. Everything is sounding a bit too glassy and bright even with full res. CD's. Although it's possible the culprit may be my Alpine PDX class D amps. But I don't think so...Also, sometimes it is very slow to respond to fast forward or rewind (audible) on USB.
I will say that playing ipod off of USB sounds noticeably better than aux in or the Ipod "adaptors" (non USB). The pure digital connection doesn't seem to sap as much bass from the ipod as the analog connections.
I don't THINK anyone's found an external drive that can run off the HU, and I believe that this is because the HU simply doesn't put out enough power. Remember, I believe Pioneer said that the HU was ment to use flash drives, and was not intended for use with hard drives. That didn't stop us, though //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif. Really, the inverter the TC posted is perfect. It's small, and if you take a little time, can be hidden.
The reason I chose the Seagate is simply because I like their quality of hard drives. I'm running a 320GB ATA and a 250GB SATA in my computer right now, both Seagates. And like I said, I don't believe it's a problem with the power handeling, but the HU not putting out enough power. People ahve gotton HD's to start up and spin, but not load data strictly from running off the HU.
I love my 690. I feel they could have done some things different with the display, I"d love a visulizer that also displayed the song name and artist, but I can live without it. EQ is enough for me. If I want anything that's REALLY precise, I'd just buy an external EQ.
Now, I've got to go take care of some things at work, and get to installing mine //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
