Great to have you here Jeff.
My question is, if the RAW file is corrupt, how can it be corrupt only part of the time? Meaning, they are flawed in LR at first, but then I restart the computer and I can recover them.
I just did the card test over 4 cards. I didn't pull the cards from the camera until they were finished writing. I loaded them to HD all the same (Delkin FW reader into front FW jack in Power Mac). No other apps were running at the time. There ended up being 4 "corrupted" images out of 158 shot over 3 cards. Each of the corruptions is unique in design (sometimes it's 10% of the image, sometimes it's 70%) One thing that IS similar is that the flaw always comes from the lower right part of the image (as seen in the sample).
Anyway, as usual, when I restarted the computer, I was able to recover the images. They will now open without the flaw. Strangely this time however, even though the thumbnail and large develop image looks good when the thumbnail is highlighted, if I switch to another image, the flaw reappears in the previous thumbnail! Then when I click back to that thumbnail the flaw disappears and so on.
