Intermittent corrupted activities

Former Member over 6 years ago

I've had my Garmin 645m since August 2018. And I've had a persistent and frustrating fault across multiple firmware versions of this watch.

It will intermittently corrupt running activities. Some runs complete and sync fine via Bluetooth to my phone or by cable to my pc. But some just error out..

These acitivies show in the summary on the watch but trying to go into them to view detail makes the watch immediately go back to the watch face. If you then try and sync via USB Garmin express will then tell me that there is and error with some files which I then have to manually remove. Which I obviously do. Meaning that activity is then lost completely.. The watch will then sync fine until a few runs more and exactly the same thing happens again. It will corrupt an activity. And I'll have to remove the files again.

I have tried multiple hard and soft resets of the watch and the same thing will occur again in a few activities time. As I've had the watch since August 2018 this has happened over multiple firmware versions. I seriously believe there is a hardware problem with my device.

I can handle a few training runs being lost but I lost a complete half marathon recently. I've logged a support request with Garmin, admittedly I should have done this some time ago but my life has been quite busy. I hope the 2 year warranty is honoured Garmin. I thought I'd pen this post in case anyone else is suffering the same issue. I'll keep this thread updated with my progress.

hi Steve,

Have you got a couple of the corrupted activities still on your device that you can attached in a reply. I'll run them through FFRT and see what happens.

Hi Mike,

I think you did try this on another file for me a few months ago. Anyway here is my most recent corrupted activity from Sunday. I appreciate you looking.

Kind Regards,

Steve

hi Steve,

FFRT reported that the .fit file you attached was 100% corrupt. When I looked at the file in Wordpad, I could see two of the song titles that are loaded on your device....and that is highly unusual. I can only suggest deleting any music that is on the device and see if there is an improvement.

cheers

Thanks, for checking Mike :)

Just to update I have had response from Garmin support they have suggested : -

My first recommendation would be to perform a disk check:

On the Forerunner: go to settings > system > USB mode and set this to Garmin.

Then:

Connect your Forerunner to the computer
Open 'This PC'
Right click on the watch and select properties
Select the tools tab
Under error checking, select check

This should resolve any issues with corruption.

However, following these steps Windows 10 still see's the watch as a device and not a drive, therefore no tools menu appears :-

Going into the device and looking at the Media and primary drives yields the same result :-

They then went onto to outline how to install garmin express and how to delete the corrupted files manually, which I already have done on quite a few occasions followed by at least 4 hard resets of the watch only to get the same problem re-occur within a few activities time.

Just another update, I've had another reply from Garmin, this time they asked

Our next step would be to chkdsk for drive issues: Check a Garmin mass storage device for errors

I'm not entirely sure if they read e-mails, slightly different this time but fundamentally the same thing, I've already previously told them the device is not mounted by Windows 10 as a drive even with the watch set to "garmin" in "usb settings".

Windows still sees it as media device so will not assign a drive letter to it. So how possibly could I run CHKDSK?? This is starting to get a little frustrating :mad:

Just to update my watch has now been sent back for a replacement under warranty.
