I have a dual boot Ubuntu/Windows system. I added a 1TB hard disk to my system, formatted it with the NTFS file system and partitioned it into 2 nominal 500 GB drives. I have been using it for months with no problems.
Then, yesterday, I thought I was formatting a removable hard disc with the FAT file system but found to my horror I had formatted one of the partritions. This partition contains/ed all my photos AND it is my backup location. So my backups have gone too.

Is there any hope?
