Why and How to use data recovery
Have you ever had someone get on your computer and start pushing keys on your keyboard, causing your computer to freeze up or shut down? Sometimes friends of your offspring do this while you are away at work, or out on the patio having a beer. Occasionally files are deliberately deleted by a vindictive spouse, or significant other, or by an over competitive co-worker. And there is always encroachment upon your system by Trojan Horses, and other “Malware”. You may also own computers that are used by employees, and occasionally abused by them.
If your computer gets to the point where your hard drive needs to be formatted, and the operating system needs to be replaced, or if you need to get deleted files back where they belong, or ******** unauthorized or illegal usage of a hard drive, there is a way to recover the data that would ordinarily be lost in such situations.
You can only use Data Recovery software to recover data from a partition that your operating system and the software do not reside upon. If the data is on your primary partition, you have to have another operating system configured as the master drive with the recovery software, and the one you want to recover data from configured as a slave. Then you can just go into the drive you are having problems with, and recover all of the data to another place, or find specific items that have been deleted, and put them where they can be found, and then reinstall them where they belong.
Undelete software understands the internal workings of the system used to store files on a disk (the file system) and uses this knowledge to locate the disk space that was occupied by a deleted file. Because another file may have used some or all of this disk space, there is no guarantee that a deleted file can be recovered. But if the space hasn't been re-used right away, there is a very good chance that you will succeed. People who use data recovery software are often amazed to find that it recovers files that were deleted months or even years ago. The best undelete programs give you an indication of the chances of recovering a file intact, and even provide file viewers so you can check the *******s before recovery.
