I tried GetDataBack, but it was not successful.
I found the Seagate Recovery software online, its a free demo, so I have run a detailed search which took about 10 hours.
It has found folders/files which could be the ones I need, but they all have a red cross through them. I have found it impossible to find a manual online to see what anything actually means, but on the Seatgate FAQ section it says something to the effect 'a red cross means it was possibly deleted but it may/should be recoverable'
Anyone familiar with the Seagate Recovery software or is there another alternative.
Now I could send it to a lab, but I am worried they will not be able to recover and charge me anyway.
