If you formatted the drive, you can try THIS, but you WILL need a different drive to recover the data to. DO NOT TRY to recover to the same disk.

Thanks for the suggestion. But my problem is i'm using Linux now.
I was able to recover 3 out 4 partitions with testdisk software. But 3partitions are only 500gb data. That one big partition has 500gb data. Any Linux supported software?
If you are using linux, and if you can mount the partition with your file manager, you should be able to sort through your data and recover to a separate disc.

I recovered 3 partitions(500gb) using testdisk and for the remaining 1partition(500gb) using photorec to recover maybe 20k files. Don't know what to do with those unnamed files. This is all without mounting.
