Data recovery in NTFS and FAT file system
FAT and NTFS file system are used to recover data which is deleted from the desktop and recycle bin. FATS and NTFS are the two methods of saving the file storage record information.
Oh Jesus, what to do now, my son has deleted my important data from the desktop and recycle bin of my computer, now how can I garner my information, it was too important, oh GOD please help me, I am getting nervous breakdown, how can I get rid from this hassle, my 10 year old son has done something terrible, he has deleted my important documents, I tried a lot to restore them, but failed every time I tried, is there any way to restore them, can any one help me out?
Hey, I am here to help you out, this article is gonna help you understand how to restore data that has been deleted from the desktop and recycle bin, just go on reading this, you will get your solution.
Normally data is stored on the hard disk of computer system. On disk there is some space assigned for basic disk system operations and then the rest of the space is used to store files and data. There is also a space where the records of physical location, properties of data and programs files on the disk are maintained. FATS and NTFS are the two methods of saving the file storage record information.
File allocation tables (FAT): It is a database system which contains an entry for each cluster on the disk. Each file on a FAT system has a “directory entry”, which stores the name of a file, the location of its starting cluster, and the size of the file. OS uses this information to get the first storage cluster of a file. It uses file allocation table to identify the remaining clusters that are used to store the file.
New technology file system (NTFS): it is a proprietary file system, where all the data is stored in the form of files instead of fixed file structures in the FAT system. Each file in an NTFS has one or more 1KB file records stored in the Master File Table (MFT). The file records are composed of attributes, which are accessed using a filename: attribute syntax. A directory in an NTFS is simply an index of filenames and some related data, stored as a 4KB index buffer in the MFT. They take the form of B+ trees, indexed alphabetically by the name of the file to enable fast searches.
When a file is deleted the Operating System marks the file name in the MFT with a special character that signifies to the computer that the file has been deleted. The computer now looks at the clusters occupied by that file as being empty and therefore available space to store a new file. The operating system does not go and wipe the contents of these clusters. The files are still there, but OS doesn’t know it.
So when a data is deleted from the desktop or the recycle bin, it is possible to store it with the help of FAT and NTFS file system, but, you have to be sure that the data is undamaged and not encrypted. Cluster remapping and transaction logging techniques are used to recover data in NTFS file system.
There come lots of third part tools which do this work of recovery from the NTFS and FAT files system. You can visit site www.impcsupport.com , it provides windows support, technical support, software’s, protection tools and so on.
