I've had this happen in the form of corrupt project files (FL Studio). There's no recovering those, unless a back-up file is securely stored.Eh the worst ive had was fukkin floppy discs being corrupted back in the mpc 2000 days....
I know my boy kicked his power cord under his desk once, he was making a beat for like 3-4 hours, shyt was immaculate then nothing.
