Hard drive controller is the circuit, which acts as an interface between CPU and hard disk, floppy disk and other kinds of hard drive. But, there are times when a hard drive controller fails, due to which you may receive some error codes. These codes may also appear if there is any hardware failure. When a hard drive controller fails or damages, the hard drive becomes inaccessible and the system becomes unbootable, this may further create serious data loss situations. In such situations, the only thing that comes to your mind is to restore the data from an updated backup file. But, in case you have not maintained any backup, then you need to use specialized hard drive recovery services to recover your hard drive data.

A hard drive controller may fail due to power outage or failure, overheating, wear and tear, etc. When it fails, you encounter some error codes. Few error codes that you encounter after hard disk controller failure are:

01H: 'Bad Command.'

03H: 'Disk write protected (floppy)'.

04H:'Request sector not found'.

20H: 'Controller failure'.

40H: 'Seek failure'.

80H: 'Disk Timeout (failed to respond)'.

BBh: 'Undefined error'.

CCh: 'Write fault'.

When you encounter any of the above mentioned error codes, all your data present in the hard drive becomes inaccessible. In these circumstances, understanding the criticality of data, you would want to recover your data. Now, when you re-install the operating system and if the process continues without any problems or errors, then you need to use a high-quality data recovery software to recover your data from the formatted hard drive. But, in case of hardware failure or hard drive controller failure, the need for hard drive recovery service arises. These services are offered by data recovery companies. These companies employ the experience of highly qualified and talented data recovery specialists to ensure complete and error-free recovery of your data. These experts repair and replace the damaged parts of the hard drive under the safe environment of Clean Rooms to ensure comprehensive disk recovery.

“Boot error Press F1 to retry.” Error in Windows

Computer users often encounter an error message while trying to boot the computer system. One such error message occurs when you try to start your computer, but it does not start as there is no operating system for it to load, due to which the boot process halts. This generally happens if the master boot record of the drive is corrupt. If the master boot record of the system is corrupt, then the only resolution would to be to format the hard drive. But, you will lose all your data from the hard drive after formatting. In such situations, a recent data backup can be used to restore your data. But, in case the backup is unavailable, then you can recover your data by using specialized hard disk Recovery services.

Consider a situation – Sometimes, when you try to start your Windows-based computer, you encounter the below mentioned error message:

“Boot error Press F1 to retry.”

After this error message flashes, the system goes through BIOS and the error message is displayed on the black screen.

Cause:

The above mentioned error message occurs because of the following reasons:

• When the hard disk is missing a master boot record or boot sector.

• When the system could not find or access the boot device.

• When no partitions are active in your hard drive.

• When the master boot record is corrupted.

Resolution:

Try to workaround the issue by following the steps below:

• Check the controller connection of your hard drive to make sure it is working.

• If the control connection is working properly, then there is a definite possibility that the problem may be caused due to MBR (Master Boot Record) corruption. In such situations, the issue can only be resolved by formatting the hard drive, repartitioning it and re-installing the operating system.

This makes the situation even worse as you will lose all your data after formatting the hard drive. In these circumstances, to recover your hard drive data completely, you will need to call hard disk recovery technicians. These are highly qualified and talented experts who powerfully extract the data from the hard drive using high-intense mechanisms. In case of physical damage, these experts provide comprehensive disk recovery by repairing and replacing the damaged part of the hard disk, whereas in case of logical data loss, high-quality software are used to recover your data.

How Data Recovery Methods Combat Data Loss Situations

In a computer system, either desktop or laptop, hard drive is the secondary memory that stores all of your valuable and significant data. The hard drive consists of circular magnetic platters and their respective read/write heads to read and write data. Disk platters are divided into tracks and sectors to actually store data and effectively manage it. However, the hard drive is a reliable storage media, it might crash because of technical, logical or environmental issues. Such behaviors result into critical data loss circumstances and need data recovery to be handled.

Hard drive crash or failure is an extremely dreaded condition that results into data loss. At this point, you are unable to read data from and write data to the hard drive. Generally a computer hard drive consists of some system resources that are used to boot the system and manage data on the hard drive. They include MBR (Master Boot Record), file system, file system table and so forth.

When a hard drive crashes, your system generally refuses to boot and give you some error message. The ideal way to prevent further data loss in such situations is to immediately turn your system off and do not attempt any recovery procedure, until you discover the cause of data loss. The recovery solutions are varying according the cause and type of data loss. Data loss situations and recovery solutions can be categorized into following two sections:

• Logical data loss and recovery: Such data loss occurs due to damage to the logical components of hard drive. It occurs in case of file system corruption, hard drive formatting, virus contamination, accidental deletion, operating system malfunction, application errors and many alike.
  Recovery in all these situation is possible through data recovery software. The applications use efficient scanning mechanisms to methodically scan whole drive and recover all of the lost data from it. The data recovery software are completely safe and easy to use.

• Physical loss and recovery: Physical data loss situations occur when damage to hard drive internals like read/write head, actuator arm, spindle motor, disk platters, PCB (Printed Circuit Board), disk controller and so forth.
  data recovery professionals will help you in these cases to retrieve your lost data. The experts have rich experience to effectively handle all types of hard drive failure situations. They use advanced tools and techniques for absolute and assured recovery.

Data Recovery Applications Over Recovery Service

However, the data loss situations are quite stressing, there is a good news for you that you can recover lost data in most of the cases using Data Recovery solutions through reliable tools.

There are some measures that you can take yourself to increase the possibilities of successful recovery, which include the followings:

• Regularly use Disk or Volume De-fragmenter to De-fragment the hard drive. It is an application, which arrange the files continuously and increase system performance. Extensive fragmentation on the hard drive may damage the file system and cause severe data loss situations.

• Always perform a system backup or create system restore point (only in Windows), before you go for a major hardware or software upgrade. In case if anything goes wrong, you can easily restore your system to previous working state.

• Never try to fix a physically damaged hard drive on your own, Opening the drive in general environment may damage its sensitive platters and can lead to irretrievable data loss.

• If the drive is experiencing logical failure, you should not run any disk repair utility (like ChkDsk in Windows, Disk Utility in Mac, VRepair in Novel and fsck in Linux and UNIX). It may overwrite the lost data and overwritten data can not be recovered even by a data recovery software.

In order to effectively handle physical data loss situations, you need to take assistance from data recovery professionals. The deliver personalized recovery service to repair the damaged hard drive and then retrieve all of the data from it. Whole recovery process is performed in safe environment of Clean Rooms and thus no further damage will occur.

Logical data loss situations are comparatively easy to handle. You can perform recovery on your own using data recovery software. The applications carry out extensive scan of your hard drive and retrieve all of the data from it. They are completely safe and easy to use.

What Constitutes Hard Drive Damage and Require Data Recovery?

It is a bitter truth that no data storage media lasts forever. This is inevitable that your computer hard drive or other removable storage media would fail or crash at some point of time. Even if the hard drive does not fail before its warranty is up, a number of hardware get damaged because some internal components become damaged. A hard drive failure results into serious data loss in most of the cases and require Data Recovery to retrieve lost, missing and inaccessible data from crashed or failed hard drive.

Companies, which manufacture the data storage equipments would provide you something that is known as MTBF (Mean Time Between Failure) number in the disk instruction manual or box of the hard drive. The calculate this figure by carrying out a test on the drive. After test, they determine how much damage the drive could undergoes. Then from the output of this process, the consider how long your hard drive before too damaged to use.

Unluckily, the hard drive manufactures could not see the future and take the factors like head crash, power surges, hard drive formatting, virus infection, file system corruption and accidental drop down into account. Thus, you should consider that the MTBF is not completely accurate. However, you could use the S.M.A.R.T (Self-Monitoring, Analysis and Reporting Technology) to regularly check health of your hard drive.

The S.M.A.R.T status of hard drive provides accurate information about the hard drive speed, temperature and all other factors. It gives you warning messages if the current values of hard drive exceeds threshold values. In such cases, you should immediately stop using the hard drive to prevent hard drive failure and need of data recovery services.

The S.M.A.R.T features is not able to detect the logical errors in hard drive. They are generally indicated by messages. When logical failure and data loss occurs, the best possible solution is to go for data recovery software. They perform extensive scan of the hard drive and carry out absolute recovery. The data recovery software are completely safe and easy to use.

If you come across hard drive physical failure and data loss, you should never try to perform any recovery on your own. Recovery professionals can help you in such circumstances to get your data back. They perform successful recovery in safe and sterile surroundings of Clean Rooms using advanced tools and techniques.
