Testdisk cannot find my partition, 1tb of data at risk

#1 Post by Danny247 » 04 Apr 2013, 01:57

Hey everyone, I've done some searching around and haven't been able to find a solution. I've scanned my hard disk multiple times with "testdisk", and it always comes up with the same result of not being able to find my partition. I don't know what might have caused this, but one day I just turned on my computer and Windows 7 showed my drive as "RAW" fileformat and as 100% disk space free. I really need to recover my data, it's everything that I've worked on for the past 7 years! If someone can help my analyze the logs that were created from testdisk below, it would really be appreciated. Thanks!
