Recovering Lost Data from Hard Drives

Clarifying the difference between repair and recovery of hard drives

Many people confuse data recovery with hard drive repair. Perhaps this is because hard drive recovery is a term often used to refer to recovering damaged and deleted files from hard drives. With a brand new super sized hard drive costing well under one hundred dollars it would be foolish to attempt a repair of an older drive. Therefore the objective of data recovery is simply that, to recover any needed files from a crashed or broken drive.

For almost twenty years the area of data recovery was the sole province of service labs. These labs, which are still needed today, are set up with ISO certified clean rooms. Only in these sterile conditions can complicated computer hard disks be disassembled. The purpose for taking these hard drives apart is to find access the data stored on their magnetic platters. Once the data is recovered to a new working drive the computer can be repaired and reloaded.

In truth with computer speed and data storage become obsolete so quickly these days the greater likelihood is that we need data recovery services so as to be able to load our precious file archives onto a new working PC when our older model eventually dies on us.

What causes failure in even the most durable hard drives?

The hard drives built over the last five years are incredibly sturdy. They seldom incur mechanical failures unless subjected to severe abuse such as being dropped or overheated. As most PCs are temperature monitored, seldom does a hard drive control board overheat. So why then do these tough new hard drives breakdown? Actually, they don’t; modern hard drives are built to an almost unbelievable standard of toughness. Many digital storage devices are now solid-state with no moving parts, making it almost impossible for them to fail. Still, we ask why do they stop working and why do we end up staring at a bright blue Windows error screen?

These hard drive failures are the result of what is called a logic crash. To put this as simply as possible, the numbers used to create actions, text and images inside your desktop or laptop computer no longer add up. The files needed to start up your computer have been corrupted by an interrupted start up, a virus or any number of causes. And now all of your computer records are locked away inside a PC that refuses to load Windows (or Linux, Or Mac OS).

Even small computer errors can require data recovery assistance

Of course you don’t have to have a completely crashed hard drive to need data recovery help. Your PC can be functioning perfectly and you still might have lost valuable emails, images or business files. Entire programs can be lost accidentally. This type of file loss is usually attributed to human error. We can all to easily click on delete instead of save, or delete folders holding hidden folders. We discover our error after it is too late and or files are fully deleted. Another cause of files being deleted is computer error. With all of the huge amounts of data our computer handles it is no surprise that an occasional file is lost when access is attempted.

There are dozens of ways in which files can be lost on your computer. And barring the now increasingly rare instance of a physical crash, you are likely faced with a logic crash causing your PCs problems.

The solution to non-functional PCs with no hardware damage

So if we don’t have a broken hard drive, but our files are lost or our PC won’t start up, what do we need to do? What is required is powerful third party data recovery software. Data recovery software is designed to enter a hard drive whether the PC it is on is starting up or not and recover lost data. With these programs one can recover data from any type of computer hard drive or digital storage media.

Primarily our need for data recovery help centers around file recovery. We seldom need to recover applications such as a Windows operating system as these can be reloaded from disk onto our replacement PC. But the pictures from your last vacation or your business records are far more difficult to replace, as are emails stored from over five years correspondence. Programs to recover deleted files are actually quite specialized. It almost seems as if each type of file lost requires a unique program to recover it. Fortunately this is not the case as we can divide data recovery into a few simple applications.

Even simple data recovery requires a program exactly matched to your needs

The first data recovery application is basic file undelete. For this we need data recovery software that supports our operating system. Basically this will likely be Windows, Mac or Linux. A quality program to recover Mac or Windows files will usually cost less than one hundred dollars. This program will recover 90% of our lost files.

Email recovery can sometimes be accomplished with a general-purpose program but is far more successful when we use a targeted program. The reason for this is that most email recovery takes place within the Microsoft Outlook email client. This is the most popular program for sending and receiving email ever created. Hence one uses a tool designed specifically to recover outlook email.

Using a specialized tool is the best way to ensure file recovery success

This same idea of one tool for each job follows suit with digital photo recovery. Camera files bearing extensions and structure proprietary to Nikon or Canon digital cameras cannot be restored with a program to recover deleted photos that cannot see them. This same approach applies to data recovery problems as simplistic as iPod recovery or as sophisticated as raid recovery.

RAID data recovery is hard drive recovery taken to its most complex level. RAID systems are a series of hard disks connected and coordinated so as to be faster and more reliable than a conventional single drive.
Whether you wish to undelete Vista files in a document folder or rescue a song deleted from your iPod you can do so with a specialized data recovery program.
