Now let's talk about the recovery process. Often when someone erases a file that they really need to get back, the first thing they do is install a data recovery utility. Bad idea! Remember, the deleted file still exists on your hard drive, but the operating system has flagged the space occupied by the file as being available. This means that if files are written to the hard disk (such as occurs when you install a recovery utility); there's a good chance that the file that you are trying to recover could be permanently overwritten. Installing a data recovery utility isn't the only thing that can cause a deleted file to be permanently lost. Normal user of a PC results in frequent file I/O operations. Many of which have the potential to make deleted files non recoverable. To recover lost data, the first thing that you should do is to turn off the computer and remove the hard drive. Next, take a spare hard drive (maybe an old one that's too small for day-to-day use), install it into your computer, and install Windows. Don't install anti-virus software (unless a viral infection caused the data loss); doing so may interfere with data recovery. Once you have Windows running using the spare drive, install your data recovery utility. Now shut the PC down and install the drive that contains the data that you are trying to recover. Next install another blank hard drive of equal size. Boot the system and then do a sector-by-sector copy (not a file copy) from the drive containing your deleted data to the empty drive. When the copy process completes, shut down the computer and remove the drive that contains the original copy of your deleted data. You're now ready to begin the data recovery process. We strongly recommend you use EASEUS Disk Copy to back up the data by sectors-to-sectors copying. Why do we recommend copying the drive prior to attempting a recovery? First, you never want to attempt a recovery on your PCs original drive. If you work directly with this drive, then there are no second chances if you make a mistake. If you are working with a copy though, and you make a mistake, you can always make another copy. The other reason why you should work off of a copy is this: If hard disk corruption is the cause of the data loss, there's a good chance the corruption will spread. As such, you must minimize your use of the corrupt drive to avoid further data loss. The coming articles in this guide will demonstrate some actual data recovery techniques. Of course, you can also use the some software to restore the data, such as EASEUS Data Recovery Wizard 4.0.1. It will do a quick work to restore data which just was deleted. Now, the recovery software is more and more powerful, safe, exact, fast and easy-to-use, such as EASEUS Data Recovery Wizard 4.0.1. You just need to click the "Deleted File Recovery" button.
