Maybe you didn’t notice some little writting errors in the pictures you took.
I had errors.
A writting problem for sure. I can’t tell what are protocols to write without errors on a CF CARD, and how it depends on its quality.
All I can say is that there were quite a few faulty cards with OT MKIIs…
I had between 2 and 4 errors like this after 7 years with OT MKI, using 16GB Kingston card, which ended full, and 1 errors with my new 64GB Sandisk Extreme.
Once I had everything fucked up, but I’m pretty sure I turned off OT while loading or writting. The card was full (16GB Kingston).
Anyway, backup !
