    How to Delete Clickfree C2 1TB CDFS Partition

    I wanted to post this in reply to the original thread at http://windowssecrets.com/forums/showthread.php/125707-How-to-delete-a-CDFS-partition-on-a-hard-drive?p=838182&viewfull=1#post838182, but since that thread is far too old it wouldn't let me. Anyway, I'm just throwing this here since I couldn't find this information elsewhere and the old instructions had a dead link and referenced an outdated FwUpdateTool version. Below are the instructions updated with current links for a Clickfree C2:

    Before proceeding with removing the CDFS Partition, I will not take any responsibility of whatever happens, IT IS ALL ON YOU!!!!!!!!! YOU WERE WARNED

    THIS METHOD IS GOING TO TURN YOUR HARD DRIVE TO A RAW FORMAT AND THAT MEANS YOUR DATA WILL BE GONE SO PLEASE BACKUP THE DATA ON YOUR COMPUTER

    The PRO about this fix is that the CDFS will be removed and the CON is that the LED FROM THE EXTERNAL HARD DRIVE WILL NOT WORK (THE HARD DRIVE IS STILL FUNCTIONAL) AND I DO NOT KNOW WHY. IF YOU CARE ABOUT THE FLASHING LIGHT, DO NOT PROCEED WITH THIS FIX!


    IF YOU ARE AN EXTREME RISK TAKER OR REALLY DESPERATE, PROCEED WITH THE FIX BUT I STRONGLY RECOMMEND THAT YOU RETURN THE HARD DRIVE AND BUY A GENERIC EXTERNAL HARD DRIVE!
    The rest is also from the original post by hayel2ko, with a handful of modifications:

    1. http://www.station-drivers.com/index....0-Controller/ click on this link and download the file that says "Version 0.00.242.00.01" (click on the floppy disk to download)

    2. Extract the file to a folder (Recommended that you make one)

    3. Go to your folder where you extracted the files and run the FwUpdateTool_v1_16_00_T2.exe

    4. When your on the tool, Select the Clickfree backup drive next to USB DISK

    5. If you see JMS539 next to chip, keep proceeding with the steps. "IF YOU SEE SOMETHING ELSE, DO NOT PROCEED WITH THE STEP OTHERWISE YOU WILL BRICK YOUR EXTERNAL HARD DRIVE"

    5A. Optional: Check the RD Version box and the "Backup Old Firmware Only" and "Include 4K NVRAM". Choose a file location and click "Run" to create a backup. Hold on to that in case you have second thoughts and want the original behavior back. Uncheck "RD Version" when complete.

    6. Select the firmware file by clicking load file and selecting the QSPortU3.bin. Errors may appear about the firmware being incorrect for the chip, though this didn't seem to matter for me

    Note: on the Clickfree C2 with the QSPortU3.bin file the light works fine, but only blinks when there's activity and won't stay lit when the drive's powered on. I tried with 255.31.3.41.22 and while the drive did work fine with that bin file, the light did not function.

    6A. AGAIN, I WILL NOT TAKE ANY RESPONSIBILITY OF WHAT EVER HAPPENS TO YOUR EXTERNAL HARD DRIVE AND AGAIN IT IS ALL ON YOU.

    7. Click run and when it says programming succeed or something like that, disconnect the clickfree hard drive and connect it.

    7A. So what we did with the Clickfree Hard Drive is that we programmed the JMS539 Bridge controller to bridge the connection directly to the hard drive and not to the Nand Chip that carries the CDFS partition.

    8. Now go to device manager (Start -> Control Panel -> Device Manager) and if you see another hard drive that you never saw before, you finished Part I of this method

    9. Now for Part II , If you don't see the external hard drive on Computer or My Computer, Do not Panic because your External Hard Drive is not formatted and doesn't have a drive letter.

    10. What I strongly Recommend for formatting External Hard Drive is to use a Linux Distro, GParted. However , if you want to use a third party formatting tool or use disk management, you can proceed with that . if you want to use my recommendation, here is the link to the iso http://gparted.sourceforge.net/download.php. And click on the Live CD/USB tab to guide you putting the iso on a cd or usb.

    11. I will not provide steps on how to boot the cd/usb and how to format the clickfree hard drive.

    12. After you formatted the External Hard Drive with Gparted (Linux Distro), third party partitioning software or Disk Management on Windows, you are officially done.

    For users that didn't get jms539 next to chip, you will have to open the external hard drive enclosure and find the sata controller chip, write down the model number and use that to find yourself a solution because you can't always depend on the internet on something like this. You have to start doing things by yourself and again not my responsibility if you screw up your external hard drive.

    To restore the drive to its original function, just use the FwUpdateTool_v1_16_00_T2.exe file to apply the backup bin file (if you created one). Once the drive is plugged back in, the original software should load up and will format the drive for you. Obviously, doing this will also result in all the data on the drive being lost, so proceed with caution.

    Yup, that's what this procedure takes care of. It overwrites the firmware on the USB to SATA chip with generic firmware that doesn't even try to read the serial flash chip with the CDFS data on it. Once done it's equivalent to removing the CDFS chip entirely, except it's reversible and won't invalidate your warranty.
