I have a external hard drive about 680 gb and it have nothing on it. After i use fat32 formatter i started to get CRC error then my other paration started to get this error too and i did cmd , couldn't do it because its readonly , raw file and crc error when i try to do it. I use kill a disk and the error i get is sector can't be read. With the crc error everywhere , i can't format it in anyway. Any way to fix this? I need this to be able to store or my file.
