I just had a card die on me as I pressed 'Import' in Aperture 3.1. The thumbnails had shown up in the import dialogue and I had selcted the images I needed, hit import and then the beachball appeared and then a message telling me the card had been improperly ejected. No images had been copied over.
The card from then onwards refused to mount on the desktop. Same on a Windows machine.
I tried the RescuePro software that comes with Sandisk cards (I was importing from a Sandisk Extreme III 8Gb, 18 months old) and PhotoRescue and a couple of other progrmas that I can't remember the name of.
The recovery programs could see the card, but when I tried to see if I could recover anything my whole system would crash (Mac OS gray screen of death - hold down power button to reboot etc). This also happened a couple of times even when I'd only just plugged the card into the reader and wasn't trying to access it!
Anyway, I've bitten the bullet and sent it off to these people:

It's expensive, my insurance doesn't cover electronic loss of data, and the client wasn't keen on a reshoot (and nor was I because it was a fair distance away and I got lucky with the light in this dreary English autumn).
Fingers crossed.
Shacklebolt, I know your initital thread post was from 4 years ago but did you have any success recovering your files?
