How is Data Recovery on a Deleted File Possible?

PACKARD BELL IMEDIA 2215:

I have a Packard Bell iMedia 2215 which I have been using as a video and movie player for my TV. This is the only way that I can view some data, such as music or videos which I have downloaded from the internet. I am now having problems connecting the iMedia system up to the TV. There was no blow-out, or any other kind of accident, but I can’t access the computer when it is connected to the TV. As I am not able to use the audio and media files on the computer without the TV, as I installed a system specifically for the television transfer which removed the ability to use Quick Player or iTunes, I am now not able to see the data on my screen at all. I need help in recovering the data so that I can view these pieces of data, and use the TV to view it.

PACKARD BELL IMEDIA 3053:

I bought a computer, a Packard Bell iMedia 3053. This was a refurbished product, and so everything had been set to factory restore when I purchased it. The problem now is that I have saved some data onto the computer, and then the PC has crashed. I was not able to burn the factory default disk as the system would not let me, and so I don’t have any way to get back to the factory restore without risking the loss of the data I have just created. I can’t lose this data, as it is important work for my company, but I don’t know how to save it before I recover the factory restore that was originally set on the computer. I don’t want to lose the data, and I also have some critical data on the system that I cannot replace and that I would love to save.

How is Data Recovery on a Deleted File Possible?

How is this possible? We tend to think that when we delete a file on our computer it is gone forever, but this is where the physical world and the virtual world do not match up. Operating systems have always been rather lazy about data deletion – if you delete a file they don’t actually remove the data from the drive, but instead simply forget that it was there. The link to the data is removed and is now reported as free space, ready for a new file to be dropped there when the space is needed.
This may seem bizarre, but it works perfectly well, and in fact makes the computer run significantly faster, as read and write operations do not really need to check every sector of a disk each time. It also means that our hard drives will last longer, as there are less read and write operations required to perform these basic day to day tasks.

It’s also true that in the vast majority of cases, this method of leaving the old files on the disk is a blessing in disguise. Most of us are not up to nefarious activities, and our hard drives are not privy to state secrets, so there is not too much to worry about having these remnants of old files lurking on the disk. In fact, when it comes to data recovery and hard drive repair, it is of great importance, as we are able to access those old files and retrieve them if there is a terrible problem with the hard drive.

Each drive has a road map if you will which points to where all the files on the drive start and stop (incidentally files can be split into many different fragments across a disk, and sometimes even across a number of disks), which works great for speed, but if this map becomes corrupted then we are left with no way to find the files that we need on the drive. This can be resolved through hard disk data recovery – either in the form of a software solution or a hardware solution.
A professional hard drive repair company will be able to recover these files for you, and usually not at an exorbitant price. They can start with the lowest cost methods of recovering the data, and if the problem turns out to be a more testy physical hardware error, give you options as to how to recover that data if it is really important to you.
