still keep the spirit I will try to demonstrate how to carve a data, you can download the file here ( to learn ) If the file is opened, an error occurs such as  

Unallocated Space

Image
we often hear the word unallocated space . for that I will discuss this time . Unallocated space is the available disk space and are not allocated to any volume . Type of volume you can create on the unallocated space depends on the type of disk . On a basic disk , you can use the unallocated space to

Basically the term is used for a particular set of 2- byte identifier at the beginning of the file , each sequence can be regarded as undecoded binary numbers, for it is a feature of a unique file format distinguishes it could be used for identification .

Slack Space

Slack space is a form of internal fragmentation , which is wasted space on your hard disk . When a file is written to disk it is stored in the " beginning" of the cluster . A cluster is defined as a set of logically contiguous sectors and the smallest amount of disk space that can be allocated to store the file . Rarely equal or match between the available space in the cluster and the number of bytes in the file . The remaining bytes in the cluster is not used , then the name of the slack space .

Filesystem Structure

To limit the size of the table , the disk space allocated to files in hardware sector groups are adjacent , so-called developing cluster. When disk drive , the maximum number of clusters also

I 'll try to explain about Master Boot Record. What is a Master Boot Record? Master Boot Record ( MBR ) is a type of boot sector is located on a Computer. It consists of a sequence of 512 bytes are located in the first sector of data storage devices like hard disks . MBR is usually placed on a storage device designed for use with IBM PC compatible with the system.
