If you have deleted an important file and you don’t have a backup, DON’T PANIC! Call Data Support immediately and ask about our data recovery service. The longer you leave it, the harder it will be to get the file back.
Do not continue to use the machine where the file was stored. If you are not in a position to contact Data Support immediately, turn off the machine that the file was stored on.
In most cases, Data Support can recover deleted files even if they have been deleted from your hard drive completely.
How To Recover Deleted Files
Here’s some background technical info on how Data Support recovers deleted files.
When you delete files in Windows, they go into the recycling bin. When you delete files from the recycling bin, they are deleted from the hard drive… but are they? Well, yes and no. Your hard drive is (for the purpose of this explaination) split into two sections, a small table containing information about the files stored and a section for the actual files themselves.
When you delete a file from the recycling bin, rather than deleting the file, the hard drive simply updates the table to say that the file doesn’t exist any more and that the space it occupies is free to be used again. Data Support is able to search your hard drive for files that have been marked as deleted and recover those files, provided that they haven’t already been overwriten.
Sometimes the location where the file was on the hard drive has already been overwriten. This can happen because the user has been creating new files or Windows has been moving files around. This is why Data Support recommends turning off the machine that the file was stored on if you can’t get hold of us immediately.
So what happens if the file is already overwriten? Well, don’t panic, it’s still possible to get the file back, albeit a lot harder. When you write a file to a hard drive (excluding solid state disks), as the metal disks spin a “head” passes a tiny magnetic field over parts to store the data to be read as 1′s and 0′s. Because this process is an analogue operation, the area of the disk that is written to is not always exactly the same. It is possible to detect a small amount of magnetic field at the edge of the readable sectors of the hard drive and therefore recreate the file that has been overwriten. This is called Data forensics and is much more costly and less accurate, so it’s best to contact Data Support as soon as possible once you know that your file has been deleted.
