The memory is divided in 128 blocks of 64 kb each. A block starts with a 76 bytes block header, which holds information about the block. The rest of the block contains data sectors and sector headers. Each data sector has a 27 bytes wide header...

The flash file systems on USB memory sticks are usually relatively simple mechanisms that only translate the Logical Block Number used in high level file systems to a low level physical address and do not support wear levelling. In the file...

FILE SYSTEM ANALYSIS
Data acquisition results in one or more binary files containing linear bitwise copies of flash memory data. Before any volume analysis and succeed ing file system analysis can take place, the sectors of data as used by the...

The most easy and non-invasive way to read flash data is by using a simple hardware interface and software that
copies all flash memory data from the target system to another system for further analysis. Unfortunately there’s no general method...
