Computer show no harddisk disc disk empty zero memory when starts what i do to recover my data from harddisk?
Try removing the disk from the computer and plugging it into another computer. If that doesn't work the disk may have experienced a "head crash", meaning that the platter is damaged. There are companies that can recover some of the data on your disk but the price is high. They disassemble the disk and replace the failed components. It generally works long enough to extract the data, but the data had better be worth it because it's expensive.
