I unlocked the drive with hd unlock but I when I use magic boot disk>config, I get an error message. Tried a third partly disk repair utility and I get an error message that the firmware is corrupted on the drive. Checked with Hd unlock and it confirms the drive is unlocked. Any suggestions would be appreciated

Thanks

Make sure the hdd is on the first IDE and is the master drive. after you start mhdd, look for your drive listed and type the number next to the drive to configure it. Then type config

Thank you very much for your advise the drive is sorted now
