Hi everyone, i am in Australia, and i just bought a G1W-CB which i am very happy with, given it was only $105au which included a 32gb Kingston micro card plus the mirror clamp (which does not fit my actual mirror)
I bought it from a sydney based supplier in Ebay, so i had it posted to me in just 3 days, BUT i was getting this last file corruption on 2 different cards after i turned the ignition off.
Some told me that my cards were compatible to record the videos, and were ok if you turn the recording off manually using the button, but not compatible when the recording stops after the ignition was turned off.
Anyway, i knew it had to be some other issue as both the cards i tried were supposed to be compatible according to the seller (given they included the Kingston card) and why would 2 totally different cards give the same error, but otherwise work with all the other functions.
Anyway, the seller sent me an email with the Firmware update process as described on the first page of this Thread, and it has fixed the problem, i now have 2014.0813.11 on the camera.
