Select quarantine next time. By ignoring it, it’s still there every time you start up, thus the re-scan with error. Quarantine will move the bad media into a “quarantine” folder in the media folder. You can delete that folder whenever you wish.
As the file is corrupt and being ignored, you would have seen it offline already. Chances are it is just a render and not missed.
I’d like to add a comment on this post and many others. Give us a little info: software version, operating system, hardware, type of storage, etc… You may not think it relevant to your problem, but perhaps it is. And in the larger scheme patterns may emerge of certain problems on specific configurations. No one of us on the Cow can have a hundred test systems but by the fact that we all share information allows us to gain insight into setups we don’t have access to. Further, a post for help that contains very little data can turn into a guessing game. If I want to play a game, I’ll invite some friends over and have them bring a 6 pack and a pizza. That is, if you cant be bothered to offer a detailed description of the problem and the situation it occurs in, why should I bother crafting a reasoned, descriptive answer. Paul, sorry to pick on you. Your post certainly isn’t among the worst. Those questions I don’t bother responding to at all.
