Fixing corrupt files on the Garmin Edge 800

Beginning in the summer I started having issues with my Garmin Edge 800.  A few tracks were corrupted but I was able to download them using Topo Fusion, so it wasn't a big deal. SportTraks, none of those files would load so I have a big gap there that I am not sure how to fill. 

After my early morning, Oh Dark Thirty Ride Before Work on Friday, I turned off the unit but when I tried connecting to my commuter it would start up and hang on the first screen.  I looked it up on the web found out how to force it into Mass Storage mode, where you hold the power key and the lap/reset button and then let off on the power and it goes into disk drive mode.

Saturday morning I tried the master reset based on what Garmin recommended you do and why:

Here are a few instances in which it may be necessary to perform a master reset on the Edge 800. A master reset should be performed if the Edge is:

• Not functioning properly
• Needing to be restored to factory default settings*
• Not receiving a satellite signal
• To bring up language selection prompt if incorrect language text is showing
• Unable to pair up accessories, such as the heart rate monitor or speed/cadence sensor

All settings, workouts, and satellite data will be erased when resetting the GPS. Workouts can be backed up in Garmin Connect. Refer to the FAQ article "How can I backup my personal settings and profiles on my Edge 800?" to back up personalized settings.

To perform the master reset:

1. Power device off
2. Press and hold Lap/Reset and Start/Stop
3. Power device on while still holding both buttons
4. Continue holding buttons when the Garmin "splash" screen appears
5. Release buttons when Garmin "splash" screen disappears

The Edge 800 is now reset. Leave the device outside with a clear view of the sky for a minimum of 20 minutes to acquire satellite data.

*A User Data Clear can be performed in order to remove personal settings without removing history.

To perform the User Data Clear:

1. Power device off
2. Touch and hold finger in top-left corner of display
3. Power device on while still maintaining pressure on display
4. Release display when the Reset device settings to factory default? message appears
5. Touch Yes

This will erase personal settings, such as the user profile. However, saved activities will not be removed.

Of course none of this worked.  After feverishly looking at many different forums I came to the conclusion that I had corrupt files.  On some website, I found some one suggesting doing a CHKDSK /F on the device.  I did that and it started working!

To play it safe, I did a User Data Clear and then reset up the device and works great now!

Not sure what to do if you have a MAC.
