Help with recovery

hey guys, i had the drive removed from the caddy, was stupidly connected to windows, now connected to a ubuntu box with sata. I have tried most of the commands, finding a step by step on here is hard. drive starts to decrypt, generates a 1.2GB file and then errors: "error running decrypt: open /media/tech/Data/~TechBackups/#33029/decrypted.img: file exists
