If you have a Nikon digital camera that camera will initially store onto its memory card all of your digital photographs in the NKS format. Similarly Canon digital cameras use an exclusive format as do popular Minolta and Olympus upper level digital cameras. These file structures are known as RAW files. Your camera saves the most complete form of your digital image in its particular RAW file format directly onto your camera’s internal storage or memory card. From there the digital information is processed and changed into more conventional formats for storage on your computer’s internal hard drive. These formats use file extensions such as JPG.

After a successful transfer has been made the normal procedure is to delete the RAW files from memory cards so that you may load another grouping of pictures. But should the transfer be unsuccessful due to an interrupted download or other problem you will need to use a third party program for memory card recovery. This software to recover memory card files is available from Remo Software.

There are two approaches one can take when attempting NTFS data recovery. The first is to simply purchase an NTFS recovery program that is built expressly and solely for that purpose. Indeed if one is attempting to recover lost or damaged files from a computer’s internal hard disk drive that has been formatted using the NTFS system this can be an extremely cost effective file recovery technique.

However a wiser course of action will probably be to buy a more generally based Windows data recovery software suite that allows for not only NTFS recovery but also recovery of files from hard drives using the older FAT system and recovery of any Windows operating system based files on attached peripheral devices. Very often these devices such as memory cards and USB flash drives are formatted in the older FAT system. The confusion results in that we can accidentally reformat an externally connected device in the new system and then have to attempt data recovery based on the newer file structure.

It’s funny how we use phrases that are common to us and transfer them to times and technologies that are new. Take for example the idea of an eraser. For most of this brings to mind an image of either a giant pink eraser removing pencil work or a chalkboard eraser sweeping across the green board removing yellow chalk words. How do these images equate to using a file eraser to permanently remove files from your computer’s digital storage? Actually they don’t when we erase files we do not remove anything.

In order to erase digital information embedded onto your computer’s hard disk drive you must overwrite that information many times with new data. If one were to attempt to do this manually it would be almost impossible as the data used for overwriting must be a completely scrambled gibberish code and the number of times the data must be overwritten is several dozen. The time required to manually erase files could take weeks. Yet a simple file eraser such as those sold by Remo Software can permanently remove one file or all of your files from your computer’s hard drive in just minutes.

A better grade partition recovery software utility must have two very important features. One is the ability to quickly scan large volumes of digital information. This feature is determined by the specific memory access algorithm used. The second important feature a deleted partition recovery program must possess is the ability to skip over bad sectors of a computer’s hard drive when they are encountered.

Surprisingly many data recovery programs do not have this ability and as a result of this simply stall or freeze if you will upon reaching a bad sector. It is bad enough when a data recovery program moves so slowly as to require hour upon hour to complete a scan of a modern 500 GB plus sized hard drive. When you believe that the file recovery tool is hard at work, and later discover it has been stalled for hours by a single bad sector you may be forced to acknowledge that the program you purchased is either obsolete or invalid to begin with.

Have you ever opened a Microsoft Word document file with a simpler program such as Wordpad? If you have, you would have noticed a file full of ASCII character gibberish. When I make this mistake I simply close the file and reopen it with Word so as to be able to read it. Many file types can only be opened and read successfully with the program they were designed for. An example of this would be Microsoft DBX files. DBX files are the file type used with the free Microsoft e-mail client Outlook Express. When we accidentally delete Outlook Express messages or our messages become corrupted we must use a program designed to recover Outlook DBX file information.

By comparison the larger Microsoft e-mail client Outlook stores all of its file information into one super file known as a PST. PST stands for personal storage. A program to recover Outlook PST information must be able to recreate the access tables to that file.

Programs used to recover Mac data will generally cost almost twice as much as those used on Windows PCs. The reason for this is simple. There are many low quality Windows data recovery programs on the marketplace that barely deliver on promises to recover your lost files. The nature of Mac recovery software is such that there is no middle ground. A program either works to recover Mac data or it does not. The entire process of recognizing during a scan the proprietary nature of Mac operating system files requires software built for only that task.

While there are hundreds of programs capable of recognizing common image and document files, corrupted Mac OS X files can only be recognized by software capable of distinguishing file structure on the unique Mac OS type/creator file system. These operating system files are used to store, open and present conventional file types placed within a Mac OS directory. Think of these proprietary Mac OS files as a special set of keys that only work on a special type of lock.

Computer hard drives are much more durable today than they were just 10 years ago. 10 years ago the control board on an average size computer internal hard drive was almost guaranteed to physically fail within the first five years of its use. This was due to improper cooling. Another problem with older computer hard drives was that the motors used had to turn a relatively heavy hard disk platter. It seems as if either the control board would overheat, the motor word burn out, or the high speed spinning platter would slip out of balance. These situations meant that your computer hard drive needed be shipped to a data recovery service laboratory so that they could rescue from it any stored files.

Today’s new tough computer hard drives seem capable of lasting for 10 years without any physical mishaps. We do however have situations where the software used to operate these drives is easily corrupted. Lately the major cause for this seems to be computer viruses. Whatever the cause, the resultant need is for data recovery. To recover data from a modern computer hard drive that has crashed merely requires that we use a program designed expressly for that purpose. These programs quickly scan through even the largest computer hard drives and return from a scan a complete list of all existing and deleted files on said hard drive.
