I thought there was a 2nd person that bought the 300gb Buffalo Tech, but that person never got back to us to let us know if it works or not. Certainly is expensive, but if it works perfectly with the car, then you definately have no want for more space and then its a one and done thing. If anybody else has the 300gb Buffalo unit, please let us know how well it works.

More on Buffalo tech 300gb...
The Buffalo tech website no longer lists a 300gb drive, looks like they replaced that with a 320gb drive. I was getting ready to pull the trigger on this one but it looks like the 320 version is 5400 rpm so I would not count on it working too well with 6FL.

Not suppose to, its suppose to automatically cut power in 5-10 mins or so, but you should test this yourself, leave the drive out in the open, remove the key, close the car and come back in 10 mins to see if the drive LED is still on. Officially, BMW's 6FL option does not support USB hard drives. Unofficially, it supports a few that do not draw a lot of power, there seems to be a pattern of 4200rpm drives that work versus higher rate of RPM which suggests that the faster the disk spins the more power it needs. Looks like there is some threshold that can vary a bit from car to car where certain drives work becuase they draw power that is under the threshold.

I corrected it to 4200 RPM. I guess some websites are advertising it incorrectly as 5400 RPM. Funny, but a search of Buffalo's site for HD-PS300U2 turns up nothing.

I'm starting to have an issue where mine will switch back to radio. Then when you look in AUX, instead of showing the name of my HD it only says USB. After a few minutes the name will show again or sometimes I have to unplug and plug back in.
I think I may need a software upgrade, but not sure. My build date is either 9/07 or 10/07 (picked up @ Welt 10/27) and I thought this switching issue was solved a while back. I have not made changes to my HD since putting it in the car. I have the Iomega eGo. Any thoughts?

That kinda happened to me..some times it did show up and some times it did not..I just changed the cable and it worked like a charm..

The cable is very important. I ordered custom length cables (6in) both for reliability as well as a clean install. I wish I had these cables when I started testing drives, most of the drives came with long or y-usb cables (the passport being the only exception)

Regarding the cables... is a shorter cable preferable, or a specific brand of cable? I've been waiting to purchase another USB HD until I get everything straight.

Is the running consensus that the problem is the power requirements of the drive? I'm considering going with a lower power option. The run of the mill external drive listed in this thread draw 5 Volts at 1 Amp. Smaller drives like those used inside the iPOD and Zune use 3.3V (http://sdd.toshiba.com/main.aspx?Pat...Specifications). A little more expensive but possibly more reliable. They could be plugged into a case such as http://insidecomputer.stores.yahoo.net/enc18aluz.html.

The 1.8in drives are gonna cost around $1.70/GB, the 2.5in drives are gonna cost around $0.65/GB.
To put that into perspective, a 160GB Ipod Classic goes for $300, which is $1.88/GB. Hopefully there will be a solid 2.5in solution, otherwise the 1.8in drives are not much cheaper than an Ipod.

I'm one of the people who got an Iomega 4200 rpm drive to work in my car. However, its been pretty problematic. It frequently hangs up between songs, and often switches back to the tuner because it loses the USB connection with the hard drive. I switched to a USB flash drive (holds much less, I know) and it has performed pretty flawlessly so far (less than a week at this point). I've also had some other gremlins with my radio and am wondering whether the hard drive has had anything to do with them.
Just wanted to let you know that even when it works, it doesn't work that well. If you can survive with 8 or 16gb of memory, the flash drive may be the way to go. I'll keep my hard drive for long trips, but don't expect to use it often at this point. |

I installed the 6" custom USB cable, couldn't be happier with the result! I regained usage of most of the armrest space as you can see and the drive still works great.

Voltmeter measurements...
Does anyone have a voltmeter and is willing to test the voltages and currents across the USB leads out of the car? Mine is broken or I'd do it.
http://pinouts.ru/Slots/USB_pinout.shtml has the pinouts for standard USB. As has been posted, the standard Pin_1 output is 5V with a current of 500mA. I suspect that the vehicle is outputting 5V and 500mA at the origin of the USB port in the radio somewhere. I'm not certain this is making it all the way to the port in the arm rest. Given the variability inherent in the USB standard voltages (4.75-5.25), I would guess that some people aren't getting enough voltage because we're actually quite far from the power source. The idea of variable cable sizes has been brought up and I think that's part of the answer - I haven't pulled up my console yet, but I'd wager that they're using pretty thin cable (<24AWG) for a run of >1m. It'd be fair to expect a voltage drop across that kind of distance with a really thin cable. I also think this is why supplemental power is working for most drives. I'd be interested in seeing what the voltage and current readouts are from Pin_1 from cars that are having success and ones that aren't. The other side of this story is, of course, the variability in specifications on individual drives. Some may require slightly more power than others, which is what I think is happening with the passport drives.

It does take some time to "show up" when the car is first turned on; I'd guess 1-2 minutes; but I think that is pretty common from what I read here. It has a built-in USB cable that is about 6 inches long. I've not found a good way to mount it to the armrest yet, so it is just sitting on the shelf inside like the picture two posts up from mine. -Dave |

Has anyone just tried a flash drive? Do they operate faster, i.e. load songs faster. I see slow start up times of 1-2 minutes just wondering if that happens on flash drives too? Im trying to figure out which one to go with. Would like 40 gigs but could probably make due with less if its much quicker.

Thats quite a bargain at $110, everything out there is over $200, ebay or otherwise.
