I was working in Final Cut Pro on a very important project (like there's any other kind) and to my horror discovered I had inadvertently deleted 30 or 40 master clips.
In a panic I looked on the Apple website and found the link to Prosoft. I downloaded Data Rescue II and to my great relief found it not only effective, but easy to use. I didn't retrieve all the files but managed to recover around 80 per cent. I... was... THRILLED.
Data Rescue II is everything you claim it to be. At $99, it would be a bargain at twice the price.
