Scary Thought...

Here's a scary thought... you've been shooting footage for 30-40 minutes on your SDHC card and suddenly you get a CHECK CARD warning. You check the card, it records again just fine and you assume it was a temporary blip. But what if, when you're ingesting that footage in to your system, you discover the clip is unreadable or completely missing? The HMC150 does not have a redundant system for recording media - you have one card slot and thus one card that can record media at any given point. Of course many cameras are this way, and if you're still recording tape there's always a risk of the tape breaking, but with tapeless media it just seems all the more scary.

There's a long and eye-opening thread about a handful of people who are seeing these kinds of problems with one particular brand of cards - Transcend. There seem to be twice that many that have replied to say they own the same brand and size of card and have had zero problems. It's worth checking out.
