Alright guys, I'm in real trouble here. I accidentally erased my main hard-drive with all my stuff on it. Worse than that, I only partially erased it, as I shut off the computer when I realised what I was doing. Worse again, the hard-drive was encrypted, which makes potential data recovery even more tricky. But it is paramount for me to retrieve as much data from the hard-drive as possible. It is a 1 TB Western Digital 'My Passport' External hard-drive. It contains important files of great sentimental value collected over the past 13 years on it. I have some partial backups from before 2009, and a 6 GB backup from 2015 with just some low file-size essentials, but that's it. If I have to pay €1000, I will to restore access to the contents in the hard-drive. I intended on formatting a flash-drive, but got confused with about ten drives and partitions available to me in Disk Utility. I selected the 1 TB My Passport hard-drive and clicked 'Erase'. A few seconds passed, as it was mounting the drive for erasure, and I realised what was happening, I shut off the computer hoping no damage occurred. Turning on the computer, the hard-drive is now inaccessible. The partition is now greyed out in Disk Utility. I have tried several Data Recovery programs with no success. I don't know what to do. 13 years of files are on that hard-drive. I'm fairly sure they are still on there, I just can't gain access to them. Please help.
