In reply to The Lemming:
Well, I had a go with Drill Down after reading a lot of reviews. I downloaded the Free Trial and it said that there was 50-60Gb of images that could be recovered but the free trial would only let me recover 500mb of information.
So I bit the bullet and bought a licence for £83.
I got £83 worth of RAW files which were completely blank. To say that I was disappointed would be an understatement.
I then tried the suggestion of PhotoRec. Its still got half an hour to go and so far it has found all my RAW images from the Air Show of the Red Arrows.
Yes I should have tried the free software first however I thought that the Paid for Software would have worked perfectly and I would have been happy to hand over the cash.
But as it is, the Paid for software did not produce the goods and I paid £83 to learn a valuable lesson.
Try the free stuff first, with the proviso that it may cause further damage to your data storage.
You pay's your money and you takes your choice.
Bottom line PhotoRec was able to find my fairly new RAW file format photos and I am once a gain a happy bunny.
