It could technically still be either PATA (IDE) or SATA. But PATA would not be very future proof, so I would assume SATA. |

Ghost doesn't provide an OS; it usually boots DOS and runs from there. That is safe, but I agree with *NEVER* booting Windows with that drive connected. And I also agree that Linux is your best bet for imaging. dd will make a perfect copy. And you are much more likely to get somewhere exploring the disk with Linux.

I stopped by the local dealership this morning and the service technician provided me with a sheet showing the partitions of the hard drive. He doesn't know where the 4GB that was put towards the entertainment partition came from, though (see marking on the diagram). Thought this might be of interest.

Note that the manual says that "USB hard drives" are not supported - I assume they are just worried about power draw.... Last edited by bsd107; 01-22-2010 at 03:08 PM.. |

also, I have 145gb (35,000 mp3s) of music so a 64gb jump drive won't cut it. lastly, the stock drive is most likely 4200 or 5400 rpm. upgrading to a 7200 rpm drive would increase the overall system speed. |

You wouldn't see any appreciable increase in speed from a 7200rpm drive, IMHO. Those drives will give a faster sustained throughput rate, but we are talking really small file sizes here, so I don't think there would be a significant impact on speed (see the web on Playstation 3 upgrades to 7,200rpm drives as an example of how there is no speed improvement in some applications). Plus keep in mind that the 7200rpm drive will run hotter.... |

Strange - especially as the iDrive is supposed to cache the index for the last 4 USB devices connected to 6FL. Hopefully searching can be added to a future software update?

You're probably right about their not being much speed increase, we'll know for sure once someone tries it. 7200 rpm drives have a much fast random seek time which I though would help when calculating routes. |

I was unable to do a search by "artist" from the 6FL. When my car gets redelivered in a month I'll have a chance to play with it more. |

I'm mainly annoyed that the New iDrive does not support a lossless codec like Apple Lossless or Windows Media Lossless. Like you, I've also found that the New iDrive will play any MP3 or WMA format (i.e. bitrate, CBR, VBR, etc.) that I throw at it, with the files on a DVD-ROM. But, no PCM WAV from DVD-ROM - only from 6FL. |

I just removed my hard drive to continue this investigation. In my 2010 (with navigation, STDRD), the drive is still a PATA. The drive info can be found here:
http://storage.toshiba.eu/cms/en/hdd...?productid=226 I use linux so I had a little more luck seeing the partition table to see the partition ID's. This is what I saw with fdisk: Code:
The number of cylinders for this disk is set to 9729. There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with: 1) software that runs at boot time (e.g., old versions of LILO) 2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK) Command (m for help): p Disk /dev/sdd: 80.0 GB, 80026361856 bytes 255 heads, 63 sectors/track, 9729 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x6ad4b821 Device Boot Start End Blocks Id System /dev/sdd1 1 9729 78148161 5 Extended /dev/sdd5 1 7311 58725544+ 4d QNX4.x /dev/sdd6 7312 7694 3076416 4d QNX4.x /dev/sdd7 7695 7907 1710891 4d QNX4.x /dev/sdd8 7908 8050 1148616 4d QNX4.x /dev/sdd9 8051 9708 13317853+ 4d QNX4.x /dev/sdd10 9709 9729 168651 4d QNX4.x Command (m for help): For more info on QNX, Google it, I like what I'm reading here: http://www.operating-system.org/betr...ish/bs-qnx.htm In linux 2.6.31, the QNX support is still experimental, but I'm not too concerned considering I will never modify the original drive. I am currently dd'ing the drive into an image on my drive and will be getting another drive for hacking soon. If there is anything we can do with this, I'm confident that we will find it. But this is something that requires a lot of care and caution as well. If anyone else plans to remove their disk in order to hack with this, even though it is QNX, I still recommend that you disconnect the battery before removal. Also, the carriage around the drive is not refined so if you don't handle it with care, the rough edges can slice through your skin. |

Wow, I haven't checked this thread in a while. It looks like the hard drive is designed for automotive environments, but that's not to say a normal laptop hard wouldn't be fine. With a rotation speed of 4200 rpm, I would think a 7200 rpm wold help speed up POI searches. However, finding a 7200rpm PATA hard drive might be difficult.
As for the OS, if it is QNX, then it could hold lots of possibilities. From what I have read on the OS, it's about as feature rich as you can get for an embedded operating system. However, not much can be done without the source code. If someone were able to get the source code from bmw, the possibilities would be endless. Here's a screen shot of the QNX gui: |

Any tips on removing the lower part of the console covering the HD?

When trying to mount the drive image, I had difficulty (I got the error "wrong fsid" in the system log), but that may be an error that I need to work out in Linux). Let me know what you come up with. I have not given up yet. There are still alternatives. |

Bump. Curious if DeFKnoL had any luck with exploring more of the QNX partitions after you mirrored the drive.

I searched around for a driver for this filesystem with no luck. I even downloaded QNX and tried mounting it under tha and still got the same results. I tried all of the Wind River demos that I could with still no results. My only assumption at this point is that BMW is using a proprietary format on these drives. Likely, the OS is in a chip in the CIC and it just knows how to read the data on the drives without even doing a conventional mount. I guess it would take some hardcore reverse engineering (beyond my current expertise) to read the data off this thing. |

Posted elsewhere: "April 14, 2010 at 1:28 am By Paul Tan: Blackberry maker RIM has just cut a deal to acquire QNX, the company which makes the QNX RTOS. The QNX system powers BMWs latest version of the iDrive system, the one with the HDD navigation."

For those of you who're brave enough to take out the HDD and do a DIY upgrade, Toshiba just came out with 100 and 200 GB versions of their specially designed for auto-infotainment hard drives:

Partition Magic will not do the trick for this hack. But, once we figure out the filesystem, these drives will certainly come in handy. Last edited by DeFKnoL; 04-15-2010 at 02:54 PM.. |

Unless someone can figure out how to mount a SATA adapter on the CIC. That would open up a new world! |
