Note: Total visible sectors are 202,400.
Assertions: AFR-01 The tool accesses the digital source with a supported access interface
AFR-02 The tool acquires a digital source
AFR-03 The tool operates in an execution environment
AFR-04 The tool creates an image file of the digital source
AFR-05 The tool acquires all the visible data sectors from the digital source
AFR-06 The tool acquires all the hidden data sectors from the digital source

AFR-07 All data sectors acquired from the digital source are acquired accurately.
AIC-01
The data represented by an image file is the same as the data acquired by the
tool
AIC-02 The tool creates an image file according to the file format the user specified.
AIC-05
If multi-file image creation and the image file size is selected, the tool creates
a multi-file image except that one file may be smaller
AIC-06
If the image file integrity check is selected, the tool shall report to the user the
image file has not been changed if the image file has not been changed.
AIC-07
If the image file integrity check is selected, the tool shall report to the user the
AIC-08

image file has been changed if the image file has been changed.
If the image file integrity check is selected, the tool shall report to the user the
image file has been changed and the involved location if the image file has
been changed.
If the tool logs any information regarding to the acquisition, the information is
accurately logged in the log file.
The tool display correct information about the acquisition to the user. The
information about the acquisition at least including following: device, start
sector, end sector, type and number of errors encountered, and start time and
end time of acquisition.
The tool display correct information regarding to the acquisition to the user
and the information displayed is consistent with the log file if the log file
function is supported
AHS-01 The tool reports to the user if any hidden sectors are found
AHS-02
AHS-03
The tool reports to the user that digital source may contain hidden sector but
undetected if the tool is unable to determine whether hidden sectors are
present due to incompatible execution environment
The tool reports to the user that hidden sectors will not be acquired if the tool
is unable to acquire hidden sectors due to incompatible execution
environment
