Where is the hard drive located?
Obviously, this would only apply to the 09's with iDrive. I'm thinking about installing a larger hard drive if the system is using a standard computer hard drive.
Depending on the file structure of the drive, it may be possible to extend the 13gb partition allocated for music. |

It depends on if they use a proprietary file system. My guess is that it's a stadard laptop hard drive running VxWorks. That would most likely mean it uses the RT-11 filesystem.

After doing some research it appears that it does use VxWorks and the RT-11 filesystem. That means it might be possible to modify the partition tables.
fyi - VxWorks is closed source. |

It is probably a 2.5" SATA disk these days.
If you can get physical access to it, I would get a second similar drive and make using Linux a byte for byte copy. You then have all the time to try to understand the partition and filesystem layout (assuming it is not something custom) without messing with the original disk. Note that I said Linux and not Windows for a reason. First of all Linux understand many more partition schemes and filesystems then windows does, second windows has the nasty habit of writing to the disk even when you think your just looking at it. |

Where did you find that? The old iDrive system was indeed based on VxWorks running on the 32bit SuperSH processor. I had not heard anything about what the new system was based on.

I planned on imaging the drive using norton ghost. I don't think making an image with ghost would write to the orginal drive. Once I have an image, I can modify it using ghost explorer. Finally, I'd dump the new image on to a new hard drive and try it in the car. |

Oh, it's possible that the information I was reading was referring to the old iDrive. Even if it was, there is still a very high chance that the new system still uses VxWorks.

The new iDrive is said to be from a different vendor then the old system, so it might not be based on the same software stack. Just like they switched from NavTeq to TeleAtlas maps for the new system.

True, thats why I posted this thread. Someone must know. Or at least have the shop manual, it should say where the hard drive is located.

When I get a new car, I plan on getting 6FL so I can just use a USB hard drive. I don't want to bother copying everything to the internal hard drive. Upgrading the drive sounds like a pain in the arse, if it is even possible.

Ghost is filesystem independent. It will make an image of anything. More than likely I won't be able to edit the image, but I can still make a back up of it.

How large is the stock drive in the car? I've been told (shown) that the navigation partition is 65GB. If the music is 13GB then with the other two partitions of 4GB and something like 12GB, this would mean a minimum of about 100GB.

Interesting math.

Well yeah, you can do a byte-level image. But that won't get you anywhere as far as actually modifying or upgrading the drive. If you restored that byte-level image to a larger drive, the partition table would define the partitions the same size as they were before, and the file systems would be the same size as before.

I would just use something like 'dd if=/dev/sdb of=idrivehdd.img' under linux. Much safer. If you do not have a Linux system, you could even just boot it from a live CD/DVD image and never even install it on your HDD. |

I'm talking about Ghost Solution, it's designed for network imaging. This OS looks similar to this. |

The BMW info on the CIC system says the hard drive is "comparable to the hard drive on a home computer or laptop." Its a 2.5" 80 GB drive. In addition, they say the CIC's modular construction make the hard drive independently serviceable - its inside the CIC in the lower half mounted on a slide-in tray. (However, BMW dealers will just replace the CIC as a unit.) If you take the bezel off the front, there is a little rectangular port in which the drive slides out backwards (towards you.) ...see attached
