    Bad sectors can not be repaired. What software actually does is to salvage as much data as posible from that sector on the disk and move it to another free sector. The damaged sector is then recorded in the file alocation table( FAT) as a "bad sector" so that your operating system (Windows, Unix, etc.) knows not to save data there. The best thing you can do is expect the harddisk to crash soon so backup all your data now!

    It Depend if it is logically damage or physically damage, you cannot repair a Physically damaged hard disk. You can use a hard disk utilities to diagnose or maybe repair your hard disk.

    (choose your hard disk manufacturer)

    I hope it helps! Good luck!

    Lo último que compre fue un hard disk externo, siempre han sido de calidad los productos que he comprado en los sitios web pero esta compra ha pasado mis expectativos, un transporte muy rápido y un producto excelente de buena marca a un precio sin igual, seguramente la mejor compra.
