Gradius, I know you must be a busy guy but would you consider performing this fix for me? I'm just not willing to risk all the data on my drive if I screw it up. I think I have the BSY error as my hard drive is powering up, everything sounds fine, but BIOS can't see anything. If you would consider it, please email me at email@example.com. Thank you for your posts here, I know you have helped countless people that the manufacturer has written off.
