Help with corrupt fit file

Former Member over 9 years ago

Might as well start a thread for this like they have over in the 500 forum.

I've only had my 520 for a week, and I really like it. The only issues I've had so far are that sometimes the bluetooth requires me to restart on the device to work properly, and then tonights FIT file is really corrupt so I can't load it over to strava.

The online FIT tool doesn't fix it, and then I opened it in golden cheetah. It seems the timestamps are all whacky, where it should be increasing every second, but it looks like the stamps are becoming integer overflows. The data is there, I just don't know of a way to edit all of the timestamps by just setting them as monotonically increasing seconds after they start getting corrupt in the file.

Any ideas?

Hi Mike, I competed in K2 today. My fit file failed to sync with "Invalid File Format .fit file not recognised" or similar.

Would you please be able to take a look and see if it has a problem…

hi jammacdo

If you can upload the original .fit file in a reply to this message or get yourself a free Dropbox account, upload the file to there and then share the link, I will see what I can do - no guarantees though until I have seen what data is in the file to manipulate.

cheers

Mike thank you very much. here https://cisco.box.com/s/tzb72eol11w52j6cgv0obtuzh4eb6i3m is the location. The larger file is the one I really want but the smaller one has the same issue. Let me know if you are able to fix and ill be most grateful. If it works I'll be able to add this as evidence for the successful World Record ride. thanks

hi jammacdo,

The link you've provided is asking me to provide a user name and password and looks like a Corporate storage site?

cheers

Really sorry Mike. Should work ok now.

hi James,

I know what the issue is with your two files - the 99,999 point limit in Garmin Connect prevents activities that are longer than 27 hours in length when using the one second recording option on devices being uploaded.

Currently there are 182564 data points in the two files when they are joined together so I will split it at 90000 data points and give you two files.

I will update this post once I have had a chance to work on it in a couple of hours.

cheers
Mike

hi James,

Does it have to be 1sec timing? I can get it to successfully work at 10sec timing and I'm trying to it to work on 5sec time. The 1sec timing is taking over hour just to import and do a simple export....

cheers

mike 10 second is fine, to be honest 1 min would be fine! the spot tracker we had was pinging every 5 mins. whatever makes it easier for you, seriously im so glad of your help.

Perfect - it loaded into Strava and Training Peaks. Some ridiculous numbers in there :) Fantastic, thanks so much for doing this - and adding the two together was great. How did you fix this? What did you use? I have the return Lands End to John O Groats to fix as well but ill give it a go if you let me know how. Don't want to add to your workload! Cheers.

hi James,

All my repairs are done using the Fit File Repair Tool which I have a license for.

cheers
