I have trashed a 4 gig and a 2 gig CF card using my Microtrack - apparently it formats the cards using a backup FAT, which appears to be non-standard. Soo...cards formatted without a backup FAT get trashed when you turn your MT on then off. I'm not sure if this issue is related to what you're experiencing or not, but the adcvice to reformat frequently is a good one (and always initially format a new card in the MT).

Good luck to us all!

How do you mean that formatting without a backup FAT is non-standard? When you format in Windows it creates a backup FAT so that seems to be the standard to me.
