There are times when your heart skips a beat, when you see your spouse for the first time, when you graduate from the university, when you get your dream job, but specially when your computer won’t start. This is one of the most terrifying moments in a working person’s life. I’m here to give you a little bit of information on what data recovery is. Remember that when in doubt don’t try to do it yourself but call your local Small Business IT Support Business to assist you.
Data recovery is the process of getting your information out of a device that won’t work anymore. This can be internal or external hard drives, USB flash drives, or if you are really old school storage tapes. The problem can be caused because of a physical, or logical malfunction with your hardware.
A physical malfunction can be caused by dropping the device while it is operating or any other damage to the hardware itself. One must common problem is head crash damage. This type of damage is done inside your hard drive by the reading head. This head is usually traveling just above the disk itself (it’s actually called a platter) on a thin film of air produced by the platter spinning. Modern hard drives can make the platter spin at 120 kilometers per hour, so if this head touches the platter imagine the damage it can do. Well, let me tell you, the damage is extensive. When a laptop is dropped while the hard drive is working this type of damage can occur. If you have this type of damage I recommend you contact your local Small Business IT Support because the physical damage to the device makes it necessary to open the hard drive preferably in a sterile environment.
The second type of damage is Logical damage. This type of damage is done to your hard drive file structure or software. There are many causes for this type of failure, the most common is a virus infection, human error or file corruption. Logical damage can cause your computer BIOS (think of it as the administrator of your computer) not to recognize your hard drive.
The most basic way to recover your data if the damage to it was not physical is to copy your information to another disk. Well, this is unintuitive but not difficult, first you’ll need to create a Live CD or DVD. Since your computer won’t start, this means there is a problem with the hard drive (in many cases) so, the use of a Live CD or DVD will allow you to boot your computer with out having to use the information in your damage Hard Drive. So, planning ahead you’ll need to download a Live CD creator like Bart PE. It will guide you through the creation process.
The best avenue to prevent data recovery, short of calling local Small Business IT Support is prevention. Learn how to make different partitions, these are like separating your hard drive in halves. You have your operating system in one and your important files in the other. So, in case of hard drive crash, your files will always be perfectly safe. Just load in your Live CD and presto, files recovered.
