In summary, before you begin the task of data recovery consider whether you are in need of laptop data recovery or recovery of files from the standard desktop computer. And if you are trying to recover deleted files on a desktop computer, does that computer use the older FAT file system or the newer NTFS? NTFS recovery is far more prevalent. A further qualifier relative to hardware is that you must determine whether you are searching for a few files or if you need to recover and save an entire hard drive. When you need to recover deleted partition files, the software you choose must be of vastly higher quality. Partition recovery takes longer and hence requires the fastest program available.
Are you simply hoping to find a few deleted files on a USB flash drive? USB data recovery is perhaps is the simplest of all file recovery. When attempting to recover lost data on your internal hard drive you may be merely trying to retrieve files that you inadvertently deleted from the Windows recycle bin. Recycle bin recovery is somewhat difficult in that the software you choose for the task should be built with this specific sorting feature in place.
In essence, the entire object of data recovery is to undelete files. And though the term undelete is in some ways a complete misnomer, it still serves us well in the world of data and disk recovery.
One final area extremely pertinent to data recovery is its opposite effect. That is not the need to recover deleted files, but the need to make sure that once a file is deleted it is removed from our computer’s hard drive or other digital storage in such a manner that it can never be again accessed. There are programs created specifically to erase data. These are a byproduct of a reverse engineering of data recovery software. Often referred to as a data eraser or disk wipe program, this software overwrites the space allocated to a deleted file numerous times with scrambled information. So, even though this program might be considered a file eraser the process of erasing data from digital storage is nonexistent. The better and more common name applied to the process and the software is that of a file shredder. Powerful file shredding software tears down the original stored data to its fundamental machine code then rewrites that information on to the space allocated as empty and deletes files many times in a random pattern. This ensures that no person or machine can ever open the information again.
