The other day I had a near miss coming around the semi-blind hairpin turn on the road I live on and wanted to get a better look at the crazy neighbor kid who's been driving like a manic around here lately. But when I got home and checked the file it wasn't there. It was then I discovered a bunch of other seemingly random missing files. So, I engaged in a round of standard Mobius troubleshooting procedures (for any dash cam really) such as installing a new memory card and testing the old one with H2testw, checking the cable and its connections, the power supply, etc., but nothing obvious turned up.
Then when I re-examined all the files on the memory card which had accumulated over a period of several days I finally realized the various missing files where all the last file before shut-down. Don't know why I missed that initially but it could only mean one thing....the super-capacitor had failed.
A quick swap with a spare super-capacitor module I had on hand and I was back in business.
I currently have four Mobius cameras that have super-capacitors installed, a few of which have been in daily service for many years and none of them have ever failed before. This is a first. Of course, any component can fail eventually.
Edit: Just the fact you can plug a new super-capacitor into the PCB and be on your way as if nothing had ever happened is one of the reasons I prize Mobius cams so much.
