Q?   What causes data loss?

A.   There are many factors that contribute to data loss. Natural disaster, computer virus, data corruption, computer crime or human errors are examples that may result in the data loss. Typically, one of more of the following symptoms may appear:

       BIOS could not detect the hard disk drive

       “Operating system not found” error

       Power surges result in “no disk drive found” error

       Strange clicking or grinding noises from hard disk drive

       No normal spinning action from disk drives

       Missing folders or files without reasons

       Accidental deletion, format or fdisk

       Natural disasters due to fire, water, crash

       Files and folders can not be accessed and more…

 

   

Q?  How does data recovery happen?

A.  If you’ve determined that your drive has a mechanical problem, you may have some difficulties to overcome. The drive might be fixable and your data recoverable, but it might require a professional repair, which can cost hundreds or even thousands of euros. The main reason for this is that work on the internals of a hard drive have to be done in a “clean room” environment. Any piece of dust on the platters can ruin the drive.

 

You could attempt a mechanical repair on your own, but you’ll need to find exact replacement parts from the exact model and version of the drive. This can be a huge challenge all by itself (even for professional data recovery experts). You might be able to replace a dead circuit board yourself, but spindle motors and read/write actuators are very difficult to deal with. Also note that opening your hard drive’s case will void its warranty. If you do decide to go this route, remember to never touch the platters themselves. The oils from your fingertips are enough to ruin the drive.

 

A problem with a corrupt file structure or disk index is solved with special software. There are some utilities, such as fdisk, built into most operating systems that can be used for this purpose, but you have to be very careful. Changing the partitions in the drive or formatting it might solve the problem, but you’ll lose all your data. Another option is to use a specialized recovery utility such as Disk Warrior to repair the problem while keeping as much of your data as possible. Some corrupted files may not be recoverable.

FAQs – Frequently Asked Questions

Q?   What is the success rate of data recovery?

A.   The success rate varies based on the type of data recovery.

For example, if you deleted your data or had a virus delete your data, the success rate is very, very high.  If you erased your operating system or formatted your machine, the success rate is very high.  If your hard drive has errors, a technician will speak to you specifically about your service.  The success rate can be very, very high to poor.  If your machine was on a cruise ship, that sank 10 years ago, but 1st caught fire and melted your laptop, the success rate is very, very poor.

 

Also know that some services do not require data recovery if their data is “lost”.  Many times we have seen data displaced because another company reinstalled an operating system but did not move the data back, and with viruses, which will hide your data.

 

Once a technician assesses your machine, they can better discuss how data recovery may or may not help recover your data.
