Use Norton8 to fix your bad Disk

For hard disks with "HDD Controller Error", most of them are caused by damage to the files on the hard disk Master Boot Record (MBR) for some reason. MBR is located in the 0 head/0 cylinder/1 fan area and is generated when fdisk.exe partitions hard disks. If the MBR is damaged, the microcomputer will prompt the HDD Controller Error. In fact, the file on the zero track is damaged. At this time, the Formatting cannot solve the problem and must be handled using special software. First, run the Scandisk command to check the C drive after the system disk is started on disk.
 
If the zero track is not damaged, use Norton8.0 to repair the file on the track. The specific practice is: Find a computer with the same built-in hard disk and the hard disk to be repaired model and with Norton8.0 software installed, connect the hard disk to the hard disk power cord, but the hard disk signal line is not connected, the jumper remains unchanged.

① Run the Disk Edit command after the instance is started. The CONFIGURATION item is selected from the menu Tools and the Read Only item is canceled;

② Select the Driver from the drop-down menu O-biect, set the Hard Disk type to Physical Disk, and click OK;

③ Select the Partition Table item from the Ob-ject menu, unplug the signal line on the intact hard disk, connect it to the hard disk to be repaired, and click OK;

④ Select Hard Disk1 and click OK. Then, in the Write Ob-ject to Physical Sectors dialog box, set Cylinder, Side, and Sector to 0, 0, and 1, and click OK. Select Yes when the Warning dialog box appears. Exit the Norton software to restore the Master Boot information of the hard disk. After the reboot, the hard disk returns to normal, and the files in the original hard disk will not be lost.

If the hard disk with zero track damage is still processed with the Norton8.0 software in the above steps, only in step 3, set Cylinder, Side, and Sector to 1, 0, and 1, and click OK. Select Yes when the Warning dialog box appears. Exit the Norton software and restart the computer. In the BIOS settings hard disk Automatic Detection column, we can see that the CYLS value is reduced by one. If the original CYLS is 2112, it is changed to 2111. It indicates that the original hard disk partition table starts from the 0-cylinder of the C disk and starts from the 1-cylinder. Save the BIOS settings and exit. After partitioning and formatting, the hard disk returns to normal. If there are other hard disks, "HDD Controller Error" is displayed during self-check ". The above method is invalid and can only be decommissioned.
