What REally happens when your data is deleted:
When your Data is deleted it will not completly deleted from your hard drove.The way to proove it is when you copy data within your hard drives it will took so much time rather than deleting it.But why you may ask,that the copying will move the data and create some where else and removing has to delet byte by byte.you are wrong.when you delete a data it will not be deleted from your hard disk completedly,instead it will be deleted just from the assignment table which is a IC in your hard system and you know the IC is Electronical part of a system and hasmore speed than a mechanical system that Hard disks have and that is why when you move your data or even deleting them will take so much less time to be completed.

The Chanse of REstoring Data
For restoring data if you unexpectedly faced the deltetion of them or there where in a Hard Drive that was formated,there is still a chanse of restoring them if you haven’t worked to much after their deleion to overwrite the data.

is there any hope?
there are some softwares that will resoter these data from the Disks directly.

What does these software do?:
these softwares will ignore the reading of the tabel assignment of your hard disk and instead will scan the whole surface of your hard disk from the byte zero to the end, after that they will create their own assignment table virtually in the operating system you are having these software installed on and save table.after that they will read the table that contains all of the information of where every data that are currently in the hard.Then you can easyly access those and restore them

Example of these softwares:I do not want to tell you bunch of these software that do the restoration because i have worked with all of them and had the best results with one of them that is GetDataBack that is wonderfully greate and will restore all of your data easyly and is is also so much light.you can restore data from a Hard Disk if data is deleted on it or a drive has been formated even you can restore data from Fdisk and deleted drives
