The Garmin Edge 820 has a sometimes temperamental colour touch screen. Today I pressed SAVE RIDE but it thought I said DISCARD RIDE. And it further thought I confirmed that. I didn’t.
This was a PB file and a nice one for the CP curve enhancement collection.
This may turn out to be a lot of work for you. It’s not worth the effort unless you’ve lost a really important file. How important can a file be in the grand scheme of things?
to cut a long story short if your Garmin is one of the newer ones that is a MASS STORAGE DEVICE, ie a USB device that appears as a drive letter on your PC, then a file recovery utility may well work.
It did for me today.
I used PIRIFORM’s RECUVA and there are a few ads pretending to be download links…carefully does it. It tries to install the google toolbar which you’ll be wary of . If you just then choose to scan and recover from the GARMIN/ACTIVITY or GARMIN/ACTIVITIES folder it will show a deleted FIT file with today’s date eg 2016-09-28-then-some-other-numbers.FIT (ie 2016 September 28th).
However your device will probably NOT have correctly finished the FIT file. so, for example, SPORTTRACKS errors out when trying to import it. Grrrr. Manually uploading to Garmin Connect also fails. Grrrr. Grrr.
So you have to fix the file.
I ALWAYS use the fit file Repair Tool (because it works) :: fitfilerepairtool.info
You may well find that the file seems to be an accumulation of your current activity and lots of (presumably discarded) previous ones. They will all be time-stamped and you will have to delete the records that are old. You may well find that the file gets allocated to the wrong date in sporttracks/garmin connect/ or whatever software you use if you have missed even one old timestamp.
That’s pretty much it.
As the title says this will probably “work” on the Fenix and Forerunner series too.
