Recover Data Files, Unerase Files

If you accidentally deleted the file
Step 1
Double-click on the Recycle Bin in Windows or the Trash on a Mac to see if the file is still there.
Step 2
If you find the file, drag it to the desktop. To return the file to its original location in Windows, click on the file and select Restore from the drop-down menu.
Step 3
If the file is no longer in the Recycle Bin or the Trash, look for a backup. If your PC is on a network that has regular backups, check with the system administrator to see if it’s possible to retrieve a saved copy of the file.
Step 4
Try using a commercial file-recovery utility that scans the disk for recognizable data (you can buy one for less than $100). When you delete a file, the operating system probably won’t erase the actual bits from the disk until it needs them for something else; therefore, you may be able to recover some data.
Step 5
If you decide to use a file-recovery utility, don’t install it on the same disk that you’re hoping to retrieve the file from, or you might overwrite the data you’re trying to recover. Launch the software from a CD-ROM or a floppy disk. And if you download it directly from the Internet, don’t download it onto the disk from which you deleted the file.
If your hard disk crashed
Step 1
Try to repair the disk first with the disk-repair utility that came with your operating system. Both Microsoft and Apple supply such programs.
Step 2
If that doesn’t work, try a commercial disk-repair utility, although success with these is somewhat limited if you didn’t install the software before you experienced the crash.
Step 3
If a disk appears to be irreparable and if the data is valuable enough, you can send the entire disk to a specialty drive-recovery service that will disassemble it and retrieve as much data as possible. Expect to pay at least a couple hundred dollars, though (payable even when they don’t recover anything). Is backing up regularly starting to sound like a good idea?

Follow the simple instruction to recover your data from formatted hard disk…
Step 1 Understand that formatting the hard drive does not remove the data from your computer. As long as nothing else is written over the top of the data, it is still available and can be recovered. It is simply invisible, so to speak. You should, however, make an attempt to recover the data as soon as possible, to help prevent the space from being used by another file or program.
Step 2 Evaluate the options that are available to you from a data recovery software. There are a large number of software products available that will recover the data from a formatted hard drive. “Uneraser” is one of the most popular, but there are many available with prices ranging from free to expensive. Doing an online search for “hard drive recovery” or “data recovery software” will give you a large number of options to choose from.
Step 3 Download and install the software that you selected in the previous step. If you selected a software package that costs money, you will need to pay before you can download the program. Otherwise, follow the product instructions for how to install the recovery software onto your computer. This is normally an automated process that requires little interaction from the user, if any at all.
Step 4 Open the software and follow the on-screen instructions to recover the data from your hard drive. At this point it is basically up to the software to do all of the work. As long as no other files, including the data recovery software you just downloaded, have rewritten the hard drive space, you should be able to recover what was previously there.

Without expensive software you can’t!
