Can't overwrite FAT32 boot sector

#1 Post by lchan79 »

Hi all,

Boot sector of my external USB HDD suddenly crashed.
I tried to recover it by TestDisk but it failed.

Code: Select all

copy backup boot sector over boot sector
file_pwrite(6,3,buffer,63(0/1/1)) write err Input/Output error
Write error: Can't overwrite FAT32 boot sector

fat32_boot_sector
 1 * FAT32 LBA                0   1  1 121599 254 63 1953503937
file_pread(6,16,buffer,63(0/1/1)) ReadFile Data error (cyclic redundancy check).


file_pread(6,1,buffer,63(0/1/1)) ReadFile Data error (cyclic redundancy check).
It seems the boot sector is damaged.
Does the boot sector become a bad sector?

Thanks.

Best Regards,
Lok
