The Toshiba HD for the BMW CIC (Car Infotainment computer) has a finite lifetime, so it's good preventative maintenance to replace it.

The CIC runs many essential features in the car (more than just maps and music), if the HD fails and you don't have an image of it, you'll need a new CIC, and to have it coded to the car.

I discuss:

- How to make a DIY sled for the cheap IDE to CF adapter (one with a 2.5" sled is a hassle to get where I'm at)
- Why not use an mSATA (or IDE to SATA etc.) adapter, the CIC OS doesn't support TRIM.

One thing I left out here is a potentially much easier method: Use pliers to carefully insert the bare adapter itself (good to do this initially for testing). It will hang in place like that without support, at least when the car is stationary.

Then use the OEM sled bracket along with something like styrofoam cut to size to wedge the IDE to CF adapter in place.

I'm linking to my own chain of follow-up comments there instead of the top level, it's 15 pages, and since it was posted years ago a lot of the information has become stale.
