Author: Integrated into a disk drive, a disk controller is a circuit, which is built onto the motherboard. It enables the CPU to communicate with the hard disk. At times, when the hard disk controller fails, you may not be able to access the saved data and encounter a few error messages. This may result in data loss. In such cases, a valid data backup can provide you with great support to restore your data. But, if you have not maintained any backup or the backup fails to restore the data, then the need of Data Recovery arises.
For instance – while formatting the hard drive during re-installation of the operating system, you encounter any one of the following error messages:
01H which describes ‘Bad Command’
04H which describes ‘Request Sector Not found’
20H which describes ‘Controller Has Failed’
FFH which describes ‘Sense Operation Failed’
80H which describes ‘Drive Failed to Respond’
10H which describes ‘Bad EEC on Disk Read’
CCH which describes ‘Write Fault’
When you encounter any one of the above error message, the data stored in your hard drive becomes inaccessible
Cause:
The main cause of the above error messages are:
Hard drive controller failure.
Hardware failure.
Resolution:
To resolve these issues, try to perform a clean re-install of the operating system. When you re-install the operating system, if the process continues without any error then you can use a data recovery software to recover data from the formatted hard drive.
However, if the problem persists, then you need to seek help from a reputed Data Recovery company. These companies provide professional Hard Drive Recovery Services to recover your lost data from physically damaged hard drive. These companies employ the experience of highly qualified technicians to provide you with accurate and comprehensive Data Recovery Services. These technicians apply intense methods to powerfully extract the data from the damaged hard drive.

When a well-configured computer system fails to recognize the installed hard drive, it generally indicates its failure. A hard disk can fail due to many reasons, counting stress developed while normal operations and exposure to certain external factors (like fire, water, magnetic waves, sharp impacts etc.). To recover lost data in all such cases, you require sending failed hard drive to Data Recovery service center.
BIOS recognizes the hard drive only when it is properly connected, configured and all its components are functioning properly. “Hard disk (s) fail” error message generates because of hard disk failure. But sometimes, BIOS give this error with some additional number codes, which are summarized below:
“Hard Disk (s) fail (08)”: This error message generates as a result of sector test failure.
“Hard Disk (s) fail (10)”: BIOS returns this error message when it can’t recalibrate the hard disk.
“Hard Disk (s) fail (20)”: It indicates that hard disk could not be initialized.
“Hard Disk (s) fail (40)”: This error signifies error with hard disk controller.
“Hard Disk (s) fail (80)”: This error indicates hard disk settings issues.
Solution
Possible solutions are:
While Hard disk failure with error code ‘(08)’, you need to replace the hard disk and restore data from backup. Sector test fails because of physical bad sectors.
To solve rest error codes, you can try these steps:
Check if hard disk is properly connected to the system. Verify that interface and power cables are connected and are in good condition. Also ensure that jumpers are appropriately set.
Make sure that CMOS setup for hard disk is correct.
If problem persists, hard disk might have gone failed. While error code ‘(40)’, issue could be related to hard disk controller. In such cases, complete hard drive recovery software can be expected. However, hard disk may also fail due to mechanical component (s) damage. You need to pack the failed hard drive in shock-proof material (as per Data Recovery experts’ suggestions) and send it to recovery center. This service is available for extracting lost information through technical and safe procedures and surroundings of Clean Rooms.
Stellar Information Systems Limited exists as the foremost providers of hard drive recovery service.

The hard disk failure is a common physical failure issue. It is largely caused due to the disk controller failure. This is the circuit which acts as the intermediate between CPU and hard disk. The error messages “Hard Disk Controller Failure” or “HDD Controller Failure”, “Inaccessible Boot Disk”, hard disk not detected in the BIOS etc. may indicate its failure.
However, the same behavior may also be seen if the hard drive is not setup or connected properly or if hard drive cable is malfunctioning. If the hard drive is not booting up at all use a bootable CD or floppy to repair it. For efficient hard drive recovery solution:
• Check if the hard drive is connected properly or not. We need to check all the connectors coming from the power supply to avoid any future issues as well like spark. We need to ensure that the power cable and the interface cable are firmly connected to the drive. Also, the interface cable is firmly connected to the motherboard or interface card.
• Make sure that the hard drive jumpers are properly set, if it is a new SATA, EIDE or IDE device. We need to check for the BIOS setup and see if the hard drive is getting detected.
• A bad cable can be another reason. The connecting cable can go bad and ultimately may result into the above mentioned symptoms.
• If all the mentioned recommendations have been applied and the issue still remains the same, it is quite probable that motherboard or the interface card has gone bad. We need to get it replaced, if under warranty or else serviced.
• The most unfortunate reason could be the controller card failure. If the hard disk is new and doesn’t contain important data, we need to get it replaced. However, if data is a concern, consult hard drive recovery service for retrieving the data.

After loading the Windows, the DVD/CD-ROM drives work properly, but we can not see the drives in “My Computer” (System can not recognize the drives.). When try to run the drives, it shows up a notice “Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code39).” Before solving this error, check the drives connection correctly, then follow the steps below:
Delete Device Manager. Most people will firstly think of Windows “Find New Hardware” when drives missed, but it does not always work out. To fix the problem: open “My Computer”’ “Control Panel” ’“System”’“Device Manager”’ “HDC(Hard Disk Controller) ”, then click “Delete”. Follow the note to reboot computer. After rebooting, the computer will find the Primary IDE Controller and Secondary IDE Controller again and install the drivers. Restart the computer again while the installation is completed. In this, we can get back our CD/DVD-ROM Drives.
The other way is by editing the registry to return the missed CD/DVD-ROM drives (Code 39 error.). Obviously, it is too risky to edit the registry if you are not familiar with it. To fix the error from the registry, carry out the following steps:
Exit and close all applications currently running on your PC.
Step1. Click Start > Run and type in Regedit, press Enter.
Step2. Look for the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\ {4D36E965-E325-11CE-BFC1-08002BE10318}
Delete any of the following registry entries under this key directory:
LowerFilters
LowerFilters.bak
UpperFilters
UpperFilters.bak
Step3. Reboot your PC and open My Computer to check that the CD-ROM drive is visible.
Also, have a look at the Device Manager to see if the yellow exclamation mark and the error code 39 are gone.
