The MBR on Seagate hard drive is damaged

"Hi, I have a Seagate external hard drive. It was working fine until yesterday I removed its USB from the computer without selecting 'safely remove hardware and eject media' option. When I plugged it back, the computer cannot detect it anymore. Then I ran a scan with the HDD regenerator and it told me that the MBR is damaged. So do you guys know a reliable Seagate MBR repair tool that can help repair the device? Thanks."
