Having just spent some time slightly panicking over the weekend trying to work out why an Ingest of two cards was throwing up so many errors, can I put in a request for the Ingest window. I had two cards to Ingest, the first one started fine and then about half way through every frame failed, and the message in the Ingest Tasks window simply said "Error copying:..." The second card failed completely, every frame saying "Error Copying...". After considering all sorts of terrible situations and the loss of the whole shoot, I finally realised that my destination archive drive (not the same as my Mac's boot drive) was full (my own fault – EOS 5DII raw files are big!).
This made me think that it would be useful if the error message PM gives in the Ingest Tasks window could give some reason why the Ingest had failed. Just a simple "Insufficient Free Space" would do. Or could the Ingest window itself compare the amount of data on the Card with the amount of free space on the destination drive and not allow the Ingest to even start if there is not enough space?
