@ Axilrod: So it is the card that is at fault here in that it should be reformatted before each shoot? Are there specific cards less prone to these type of failures?
I'm just starting to do videos and I'd like to avoid these problems. Thanks.
I have 10 Sandisk Extreme 16GB and 32GB cards and have been very happy with them overall. I've recorded 80 bands since August and these were 3 camera setups so there were a lot of CF cards involved. Out of all those times I can only recall running into corrupt files once, maybe twice, and I never could figure out the cause. The strange thing was that the corrupt files were surrounded by files that were perfectly fine (for example band records 8 songs in a row, 4th and 5th are corrupt while others play fine), I'm still not sure what caused that exactly. The only thing I can think of is maybe being swapped between cameras, copied, and emptied over and over caused the card to have trouble overwriting data (since it's still there even after you delete it or format the card). So I can't say for sure what caused your corrupt files, but yes it's generally good practice to format your cards after you get the data copied.
The only other time I have had to pay to recover files was when someone accidentally formatted a card that hadn't been copied over yet. The companies recovering the stuff are making a killing, they send you a "custom repair kit" for $99, but most likely they just have a few different repair kits that they send depending on the situation and then act like they have some genius making you your own personal recovery app.
Overall the Sandisk cards are very, very reliable and I believe the only reason I have run into issues with them is volume and frequency, I just shoot so damn much on so many different cameras that I was bound to run into issues eventually.
