This is the best $100 I ever spent. I've been busy the last few weeks ripping CDs, embedding artwork and sorting things out in a 1TB plus Apple lossless library, before I put all my stuff in storage and travel for a while. Its been a complete disaster. I wanted to put a SSD and a 1TB drive in a MBP thinking iTunes was only 920GB when in reality it is closer to 1TB due to the way iTunes addresses the 1024 bit in a meg thing. I moved everything to a seagate goflex 2TB FW800, thinking I'll boot into that and continue working and then image it over to a 2 x 1TB RAID 0 in the MBP. A week ago I killed my back up drive (plugged in the wrong power adapter) and I thought then how unlucky would I have to be to kill my main as well in the next . The other day we had a major electrical storm and I switched everything off, not realising that I'd postponed a restart after a software update a few days earlier. I'd corrupted the main drive and after trying a few things made it worse, without having made a back up because i was waiting to buy a new drive. I was heartbroken thinking I'd need to use a old 3 week back-up and lose all that work. Tech Tool Pro has helped me out heaps of time in the past, but it was too far gone for it. I googled for data recovery and found a few threads around the place recommending Data Rescue 3. I downloaded the demo and DR3 did a scan of the drive and showed a graph representing read speeds. The data recovery allowed me to pinpoint the music folder and then direct the recovered files via target disc mode to a Mac Pro. You'll have to excuse my dodgy way of doing things while the wait for Thunderbolt proper continues. It took 10 hours to recover the 1.04TB. I hope starting this thread doesn't make me seem like a shill, but I am so impressed by this software and ever so grateful for getting my files back.
