I just upgraded from a 2 gb SanDisk Extreme III CF card to a 4 gb SanDisk Ultra II. I formatted the card in the MT. I have a good amount of shows coming up and wanted to test the strength of my battery while recording at 16/44 vs. 24/48. When I hit the record button, I get a message on the screen that says "Media full", even though there is nothing on the card and it was just formatted in the MT. With another push or 2 of the record button, it records without issue.
I let it record until the battery died, then re-charged it overnight. I re-formatted the card, hit record, and got the same error message. Has anyone come across this before? Should I be concerned?
For those that are interested, I was able to record for a whopping 2:46:51 @ 24/48 (with no phantom power) and a stunning 3:24:54 @ 16/44, again without phantom power.

Kind of takes away the stealthiness of the unit when you need to carry around a backup USB battery pack....
