TC-17 Acquire a partially hidden GPT Partition Test Case TC-17 Acquire a partially hidden GPT Partition (Helix3 Pro 2009 R3) Test & Case Summary: Acquire a partially hidden GPT Partition Notes: Hard drive partitioned as GPT disk. 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 Source Device: 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 ALOG- 01 ALOG- 02 ALOG- 03 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 Source Hashes: MD5: 795830763fb69dbc4a08d99c010f967a SHA1: 177b71e876a8595edd1dafbf221b5af4178afecd 247
