Harddrive Data Recovery | Basics of Data Recovery

Hard Drive Recovery or repair is almost a misnomer. Once a hard drive begins to fail nothing can stop it. There are, however, options that may save your data's life.

Common Causes/Symptoms of Data Loss in HDD Drives

• Computer won't boot
• Inaccessible drives and partitions
• Applications that are unable to run or load data
• Corrupt files/data
• Bad sectors
Virus Attack
• Hard disk drive component failure
Hard Drive Crash
• Fire or water damage
• Media surface contamination and damage
• Accidental reformatting of partitions
• Accidentally deleted files

Data Recovery Techniques

Basic questions which needs to be answered before recovery process

1. What is the data which needs to be recovered?
2. What type of hard drive is it?
3. How much data is on the hard drive?
4. What happened when the drive failed?
5. How fast do you need the data?

Recovering critical data is a specialized process that requires the right software, hardware and advanced techniques. In many failure-related cases, the chances of recovering data from a damaged hard drive range from 90-100%. If the electronic system is the only thing affected, then the drive can often be reused after the electronic control panel has been replaced. If, on the other hand, the defect is of a mechanical nature, then recovery will be a bit more difficult, which can be taken care at any Data Recovery Companies lab.

If it is problem related to the file system, which has caused inaccessibility of the data then it can be recovered using Data Recovery Software, an independent review has been posted on my website which lists the best in the field and helps you to identify the correct solution.

Hard Drive Recovery Tips

The first and most firm rule of thumb for preventing a loss of your data is to do complete and regular Hard Drive Backups! This is also the rule that most people do not bother to follow. Today, with a multitude of options for backing up your hard drive there really is no excuse for not doing so. Cheap and affordable USB hard drives can act as redundant storage for your computer, making copies of your entire hard disc drive with the push of a button. A flash drive itself can be used as a backup medium for smaller amounts of personal files as well.

On a regular basis every computer owner should run the Scandisk utility that is included with your Windows installation. Right click on your hard drive's icon, select Properties, select the Tools tab, and click on Error Checking. This utility scans your hard drive for areas that have corrupted information. Such sectors of bad data are often a prelude to a looming hard drive failure. If bad sectors are found you should immediately back up your data and consider replacing the drive in the future.

If your hard disc drive has shown the final warning signs of failure and will not allow your computer to boot you have very few options.

• If possible, backup your most important data immediately.
• Disregard your program files and other software as it can be reinstalled from your original discs.
• Save the data that cannot be replaced first.

If the computer has stopped working or refuses to boot up turn the computer off, unplug it, open it up, and carefully remove the hard disc drive from the case. Place the hard drive in a zippered freezer bag, seal it tightly while pressing out as much air as possible, and THROW IT IN THE FREEZER.

Leave the hard drive in the freezer for 24 hours. In the meantime, go to a working computer and download a shareware copy of Hard Drive Mechanic and install the software onto a blank floppy disk.

The next day, reinstall the hard drive as quickly as possible, boot the computer from the floppy disk you copied the Hard Drive Mechanic to, and start it up. With luck, the drive may continue to work long enough for you to backup your files, but the Hard Drive Mechanic software is there to help you should there be no other option left.

Computer Data Recovery Safety Tips

If your system has "crashed" and you can no longer access the operating system or see the drive in the BIOS, then shut the system down immediately and do not run any further power through the drive by attempting reboots. This is considered a physical problem with the drive and is an extremely sensitive issue. If the head stack inside your drive has been damaged, you may cause further additional damage to the platter/s of the drive, upon which your data is stored.

If you have deleted a file or files or accidentally formatted your drive, then the most important thing to remember is to NOT write or install ANY new information onto that drive. Deleting files simply removes the locating tag of the file, but the file is still intact on the drive. If you add new data to the drive, you may over-write your lost data; losing it forever. Using advanced software or contacting Data Recovery Expert can re-assemble the binary code and restore your files.

If your partition has become corrupted, the most important thing to remember is NOT to attempt a re-install of your operating system or add new data to the drive. Again, contact Data Recovery Expert to use specialized software and techniques to repair the partition and/or extract your data.

If you have deleted a partition, do not attempt to restore it by formatting the drive as this will only result in the addition of an empty partition. It will not recover your data.

If you experience a single file corruption, be sure not to attempt creating a new file with the same name as this will partially over-write the file and will greatly decrease our ability to recover fully.

Though computers are widely used not many people know what to do in the event of a computer breakdown. How you handle your data recovery process will determine whether information is salvaged or permanently lost. This procedure should ONLY be attempted by a Data Recovery Specialist.

Note: IF YOUR SYSTEM HARD DRIVE EMITS UNUSUAL NOISES (CLICKING, GRINDING OR METAL SCRAPING), TURN IT OFF IMMEDIATELY! This symptom typically indicates a head crash that can destroy your data. Hard drives spin with extreme speed; therefore, wide damage can occur in a short period of time. Contact Data Recovery Specialists immediately, as this situation demands professional recovery.

Virus Protection : How to remove Virus from USB Drives

One of the ways by which a virus can infect your PC is through USB/Pen drives. Common viruses such as ’Ravmon’ , ‘New Folder.exe’, ‘Orkut is banned’ etc are spreading through USB drives. Most anti virus programs are unable to virus clean up and even if they do, in most cases they are unable to delete viruses, only quarantine it. Here are the things which you can do for virus protection of your USB Drive.

Whenever you plug a USB drive in your system, a window will appear similar to the one shown below

Virus Protections Trick

Don’t click on Ok , just choose ‘Cancel’. Open the Command Prompt by typing ‘cmd‘ in the run box. In the command prompt type the drive letter: and press enter . Now type dir /w/a and press enter.
This will display a list of the files in the pen drive. Check whether the following files are there or not

• Autorun.inf
• Ravmon.exe
• New Folder.exe
• svchost.exe
• Heap41a
• or any other exe file which may be suspicious.

If any of the above files are there, then probably the USB drive is infected. In command prompt type attrib -r -a -s -h *.* and press enter. This will remove the Read Only, Archive, System and hidden file attribute from all the files. Now just delete the files using the command del filename. example del Ravmon.exe. Delete all the files that are suspicious. To be on a safer side, just scan the USB drive with an anti virus program to check whether virus clean up is complete or not. Now remove the drive and plug it again. In most of the cases, the real culprit turns out to be the “Autorun.inf” file which mostly gets executed when someone clicks Ok in the dialog window which appears above. Thus the infections can spread

Security Tip

Disable the Autoplay feature of USB drives. If you disable the Autoplay feature of USB drives, then there are lesser chances of the virus spreading. A tool which can perform such a function is Tweak UI. Download it from here install it.

Run the program. Now you can disable the Autoplay feature of the removable drives as shown above. By following the above steps, you can keep your USB virus protected.
Update: Tweak UI is a freeware software you can download it here:

Increase Hard Disk speed in Windows

If you like to increase, optimize your Hard Disk IO - readwrite speed without buying expensive software utilities to do that job or changing the HD, just follow next steps. With doing these steps you will increase Hard disk speed (depends of manufacture and specification, but its worth to try). The most speed improvement is visible with IDE drives; however there are reports that this tweak also does good for SCSI disks.

In any case, it won't harm your system, so try it yourself and let me know what you find!


1. Run SYSEDIT.EXE from the start & then Run command.

2. Expand the system.ini file window.

3. Scroll down almost to the end of the file untill you find a line called [386enh].

4. Press Enter to make one blank line, and in that line type

5. Irq14=4096 (note This line IS CASE SENSITIVE)

6. Click on the File menu, then choose Save.

7. Close SYSEDIT and reboot your computer.

8. Restart windows!

The speed improvement will be noticed just after the system reboots, any system info. software can be used to check the improvement.
